Item 1.  Business

Supertex, Inc. ("Supertex" or the "Company") is a technology-based
producer of high voltage analog and mixed signal semiconductor
components.  It designs, develops, manufactures, and markets
integrated circuits utilizing state-of-the-art high voltage DMOS,
HVCMOS and HVBiCMOS analog and mixed signal technologies.  With
respect to its DMOS transistor products, the Company has maintained
an established position in key products for telecommunication and
automatic test equipment industries.  Supertex has been an industry
leader in high voltage integrated circuits (HVCMOS AND HVBiCMOS),
which take advantage of the best features of CMOS, bipolar, and DMOS
technologies and integrate them into the same chip.  They are used
by the flat panel display, printer, medical ultrasound imaging,
telephone, telecommunications and instrumentation industries.

The Company markets its products through direct sales personnel,
independent sales representatives and distributors in the United
States and abroad, primarily to electronic equipment manufacturers.

The Company was incorporated in California in October 1975 and
conducted an initial public offering of its Common Stock in December
1983.  Its executive offices are located at 1235 Bordeaux Drive,
Sunnyvale, California 94089, and its principal manufacturing
facilities are located at 1225/1231 Bordeaux Drive, Sunnyvale,
California 94089 and at 71 Vista Montana, San Jose, California
95134.  Supertex also maintains four direct field offices located
in: (1) New York; (2) Texas; (3) The United Kingdom; and (4)
Germany.  The telephone number of its headquarters is (408) 744-
0100.  The Company's mailing address is 1235 Bordeaux Drive, P.O.Box
3607, Sunnyvale, California 94088-3607.

Products

Supertex offers semiconductor products that interface between the
low voltage computer logic signal world and the high voltage
requirements of the real analog world.  Most of our products use
mixed signal technologies.  We supply standard and custom interface
products primarily for the following three market groups:

  The Telecommunications Group consists of interface products used
  in telephone handsets, solid state relays, modems, fax, ISDN,
  networking, PABX, and PCMCIA cards, as well as diagnostic,
  curbside, set-top and central office equipment.  In addition,
  they are used in military radio frequency and microwave
  communication applications.
  The Imaging Group consists of interface products for Flat Panel
  Displays and Non-impact Printers and Plotters. The flat panel
  display product family is sold to customers using Electro-
  Luminescent (EL), Plasma, Vacuum Fluorescent, Plasma- addressed
  LCD, Ferro-electric LCD, and Field Emission Display (FED)
  technologies. There is also a family of products for driving EL
  panels to back-light displays in  hand-held instruments, such as
  cellular phones, PDAs, pagers, HPCs, and meters. The printer
  product family is used in ink-jet and electrostatic types of
  printers and plotters, which are mostly high end products, with
  full color capability, high resolution and high speed output.
  The Medical Electronics Group consists of products primarily for
  ultrasound diagnostic imaging equipment as well as selected
  portable instrumentation applications.

Supertex has been a leading provider of products to these specific
markets, therefore we have been able to work very closely with key
customers to define new products by determining future market needs.
Such close collaboration has produced a wide range of leading edge
new products for Supertex and has allowed our customers to quickly
develop new and more advanced products for their markets.

In the DMOS transistor product line, Supertex focuses on certain
niches such as very low threshold and low leakage devices which are
most suitable for telecommunication, automatic test equipment, and
hand-held applications where these features justify a premium.  The
DMOS transistor products also serve as predecessors

<PAGE>

to a fully integrated solution such as high voltage integrated circuits.

Research and Development

Supertex incurred expenses of $8,468,000, $7,195,000, and $5,582,000
on research and development activities during fiscal years 2000,
1999, and 1998, respectively.  Research and development activities
in fiscal 2000 continued at the rate of over thirty new product
projects per year.

We believe that our position as a leading supplier in our targeted
markets can only be maintained through continuous investments in
research and development.  We focus our efforts on designing new
products with existing process technologies while also developing
new process technologies to be used for future products.   We
continuously strive to effectively monitor and control our research
and development programs  in order to obtain better performance and
greater technological achievements at lower costs.

Manufacturing

Manufacturing operations include wafer fabrication, limited assembly
and packaging, product testing, and quality control.

We subcontract most of our standard component packaging and limited
testing to independent assemblers, principally in Thailand,
Malaysia, the Philippines, and Taiwan.  A specialized assembly area
is also maintained at our manufacturing facilities to package
engineering prototypes, to ensure high priority deliveries, and to
assemble high reliability circuits required in military and other
high reliability applications.  After assembly, packaged units are
shipped back to our facility or to testing subcontractors for final
product testing.  Quality control is performed at our headquarters
before shipment to customers.  Although our off-shore assembly and
test subcontractors have not experienced any serious work stoppages,
the political situation in these countries could be volatile.  Any
prolonged work stoppage or other inability to assemble products
would have a material adverse impact on our operating results
although we have qualified assemblers in different countries to
reduce risk.  Furthermore, economic risks, such as changes in tariff
or freight rates or interruptions in air transportation, could
adversely affect our operating results.

As a result of our acquisition on February 1, 1999 of the six inch
wafer fabrication (fab) facility in San Jose, California from Orbit
Semiconductor, a subsidiary of the DII Group, we believe that we are
well-positioned to fulfill our wafer manufacturing capacity needs
for the near future.  Since the acquisition, we have ramped up the
production volume of the new fab consisting of foundry wafers and
correspondingly ramped down the production volume of our old fab.
Our current goal is to complete the conversion before the end of the
FY2001 at which time we may sell the equipment in the old fab and
sublet the space.

The availability of blank silicon wafers has improved considerably
in the past years.  Assembly packages and other raw materials we use
in the manufacturing of our products are obtainable from several
suppliers.  Some of these materials were in short supply in prior
years, but recently the supply of these materials appears to be
plentiful and subject to competitive pricing pressure.  However, any
future shortage of supply would have a material adverse effect on
our operating results.  As is typical in the semiconductor industry,
we must allow for lead times in ordering certain materials and
services and often commit to volume purchases to obtain favorable
pricing concessions and resource allocations.


Environmental Laws

Government regulations impose various environmental controls on the
waste treatment and discharge of certain chemicals and gases after
their use in semiconductor processing.   We believe that our
activities comply with present environmental regulations.  However,
increasing attention has been focused on the environmental impact of
semiconductor manufacturing operations.  While we have not
experienced any material adverse effects on our business or
financial results from our compliance with environmental regulations
and installation of pollution control equipment, there can be no
assurance that changes in such regulations will not necessitate our
acquisition of costly equipment or other requirements in the future.
We work closely with pollution

<PAGE>

experts from federal, state, and local agencies, especially from the
cities of Sunnyvale and San Jose, California, to ensure that we are
in compliance with present requirements.

Sales

We market our standard and custom products in the United States and
abroad through our direct sales and marketing personnel in our
headquarters, as well as through independent sales representatives
and distributors supported by our field sales managers out of our
sales offices in New York, Texas, the United Kingdom, and Germany.

Export sales are made primarily through independent distributors to
customers in Western Europe and the Far East, and represented 36%,
51%, and 53% of net sales in fiscal years 2000, 1999, and 1998,
respectively.  Exports to the Far East are largely to customers in
Japan.  Export sales are denominated only in U.S. dollars.  Although
export sales are subject to certain governmental commodity controls
and restrictions for national security purposes, we have not had any
material adverse effects on our business or financial results
because of these limitations.

In fiscal 2000, two customers Microtek and Dii Semiconductor
accounted for 12% and 11% of net sales respectively.  Sales to
Microtek made up 16% and 19% of net sales for fiscal 1999 and 1998,
respectively.  We have no long-term production agreement with
Microtek.  Normal terms and conditions of sale apply, which include
a 60-day notice of cancellation and charges for work-in-process for
cancellations of less than 60 days from shipment.  Outstanding
accounts receivable from Microtek and Dii Semiconductor accounted
for 10% and 17% of gross accounts receivable as of March 31, 2000,
respectively. While we maintain a good relationship with Microtek,
Inc. and Dii Semiconductor, a breakdown in that relationship could
materially and adversely affect our business and financial results.

Inventories are stated at the lower of cost (determined on a first-
in, first-out basis) or market value.  Our inventories include high
technology parts and components that are specialized in nature or
subject to rapid technological obsolescence.  While we endeavor to
minimize the required inventory on hand and consider technological
obsolescence when estimating amounts required such estimates may be
inaccurate and are subject to change.

Revenue from direct sales to end-user customers is recognized upon
shipment of products.  Sales to distributors are made primarily
under arrangements allowing limited price protection and the right
of stock rotation on merchandise unsold by the distributors.
Because of this uncertainty associated with pricing concessions and
possible returns, we defer recognition of such sales and the related
costs of sales until the merchandise is sold by distributors to
their end-user customers.  Material miscalculation in amounts
reported by distributors could have a materially adverse effect on
our business and financial results.

Backlog

Our backlog at March 31, 2000 was approximately $25,938,000,
compared with $17,139,000 and $15,339,000 at March 31, 1999 and
1998, respectively.  1We expect that all of the current backlog will
be shipped in fiscal 2001.  Customers may cancel or reschedule
orders without significant penalty, and the price of products may be
adjusted between the time the purchase order is booked into backlog
and the time the product is shipped to the customer.  For those
reasons, we believe that backlog is not meaningful in predicting our
actual net revenue for any future period.

Competition

Because of our market niches, market statistics are not generally
available for many of our products.  Competition in general among
manufacturers of semiconductor components and discrete transistors
is intense.  Many of our domestic and foreign competitors have
larger facilities, financial, technical, and personnel resources,
and more diverse product lines.  Factors such as product prices,
product performance, diversity of product lines, delivery
capabilities, and the ability to adapt to rapid technological change
to develop new and improved products are the principal methods of
competition in the industry.  We believe we are a leader in

<PAGE>

important segments of our product families where we have a
technological and/or cost advantage and that we are generally
competitive with respect to these factors.

Patents and Licenses

We hold numerous United States patents which will expire between
2000 to 2018 and we have applications for additional patents
pending.  Although we believe that our patents may have value, there
can be no assurance that our patents or any additional patents that
may be obtained in the future will provide meaningful protection
from competition. We believe that our success depends primarily on
the experience, creative skills, technical expertise, and marketing
ability of our personnel rather than on the ownership of patents.
Patents may, however, be useful for cross-license purposes and have
served the Company well in the past.

Supertex is not aware that any of its products infringe on any valid
patent or other proprietary rights of third parties but it cannot be
certain that they do not do so.  If infringement is alleged, there
can be no assurance that the necessary licenses could be obtained,
or if obtained, would be on terms or conditions that would not have
a material adverse effect on the Company.

Employees

At March 31, 2000, we had 399 full time employees.  Many of our
employees are highly skilled, and our continued growth and success
will depend in part on our ability to attract and retain such
employees.  At times, we as well as other semiconductor
manufacturers experience difficulty in hiring and retaining
sufficient numbers of skilled personnel.

We believe that the compensation, benefits, and incentives offered
to our employees are competitive with those generally offered
throughout the semiconductor industry.  There are no collective
bargaining agreements between us and our employees, and there has
been no work stoppage due to labor difficulties.  The Company
considers its employee relations to be good.

Item 7.  Management's Discussion and Analysis of Financial Condition
and Results of Operations


Cautionary Statement Regarding Forward Looking Statements This
Annual Report on Form 10-K includes forward-looking statements.
These forward-looking statements are not historical facts, and are
based on current expectations, estimates, and projections about our
industry, our beliefs, our assumptions, and our goals and
objectives.  Words such as "anticipates", "expects", "intends",
"plans", "believes", "seeks", and "estimates ", and variations of
these words and similar expressions, are intended to identify
forward-looking statements.  Examples of the kinds of forward-
looking statements in this report include statements regarding the
following:  (1) we believe we are a market leader, (2) our new fab
will fulfil our wafer manufacturing capacity needs, (3) current
backlog will be shipped in fiscal 2001, and  (4) our patents may
have value and may be useful for cross-licensing.   These statements
are only predictions, are not guarantees, of future performance, and
are subject to risks, uncertainties, and other factors, some of
which are beyond our control and are difficult to predict, and could
cause actual results to differ materially form those expressed or
forecasted in the forward-looking statements.  These risks and
uncertainties include those described below in "Risk Factors" and
elsewhere in this report.  Except as required by law, we undertake
no obligation to update any forward-looking statement, whether as a
result of new information, future events, or otherwise.

Risk Factors  Semiconductor companies as a group are subject to many
similar risks.  These include the risks that (1) the demand for
semiconductors decreases as the industry has historically been very
cyclical,  (2) there are shortages of raw materials and/or fab
capacity, (3) there are changes in underlying circuitor process
technology or fab technology, or (4) there is litigation regarding
third party patents.  Other factors that could affect our future
results include whether we can generate new bookings from both new
and current products; general economic conditions, both in the
United States and foreign markets, and economic conditions specific
to the semiconductor industry; risks associated with customer
concentration; our ability to introduce new products, to enhance
existing products, and to meet the continually changing requirements
of our customers;

<PAGE>

whether we can manufacture efficiently and control costs; and our
ability to maintain and enhance relationships with our assembly and
test subcontractors and independent distributors and sales
representatives.   In addition, we are subject to the below-described
risks which are specific to us and our business:

  -    We have focused our product offerings primarily on niche
       markets which leverage our capabilities and which we believe we can
       dominate.  We attempt to choose markets which are sizable enough to
       be worth pursuing but which are not large enough to attract fierce
       competition.  These markets could grow enough to attract increased
       competition or else competitors could enter due to happenstance or
       down-turns elsewhere.  In addition, these niches might be more
       susceptible to shrinkage than more diverse markets, due to their
       concentration on a few product offerings.
  -    We are dependent upon one fab which we own and operate,
       assuming successful conversion from our four-inch to our six-inch
       fab.  We would be susceptible were this fab to be unable to meet our
       needs, for example, were this fab to become obsolete due to process
       technology changes, or to be damaged, for example by fire or
       earthquake.  We could encounter difficulties in operating our fab,
       such as contaminants in the air or defects in equipment, which could
       affect yields and production.
  -    We have several competitors which are substantially larger and
       could bring to bear substantially more resources in our niche
       markets.  We have been able to maintain high margins in part because
       of our dominance of most of our niche markets.  Increased
       competition could cause our margins to decrease.
  -    Our outstanding stock is owned more than 25% by Henry Pao,
       President, CEO, and a director, and his father and brother.  They
       have no agreement among themselves to act together with respect to
       the Company or their stockholdings. Were they to act in concert,
       they would be our largest shareholder and would have an ability to
       elect one or more directors, to direct management, and to delay or
       prevent a change in control.
  -    We sell a substantial amount of our products internationally.
       Problems with foreign economies or wars, or changes in the exchange
       rate, could adversely affect our foreign sales.
  -    We depend upon two customers for approximately 23% of our
       sales, even though one is our primary distributor in Japan and the
       other is a foundry customer.  Customers can typically cancel or
       reschedule orders without penalty so decreased demand for our
       products could translate into decreased sales very rapidly.
  -    We are very dependent upon continued innovation of our
       engineers.  The competition for engineers with relevant experience
       is extremely intense in the Silicon Valley, where most of our
       engineers are located.  We must compete in terms of salary,
       benefits, and working conditions with many start-ups which can offer
       more equity. We have started an IC Design Center in Hong Kong where
       competition is not as intense.
  -    We are dependent upon several key persons for management and
       engineering expertise.  Their loss would be detrimental to us.

Results of Operations

Fiscal 2000 VS Fiscal 1999

Net Sales:  The Company had net sales of $70,838,000 in fiscal 2000,
an increase of $20,117,000 or 39.7% from the previous fiscal year.
The increase in the current year's net sales is primarily due to the
addition of the foundry business resulting from the acquisition of
the submicron wafer fabrication facility (fab) on February 1, 1999.
This foundry business represented 32.3% of the total increase over
fiscal 1999 net sales. The remaining 7.4% of the increase over
fiscal 1999 net sales is due to increased sales of core products.

In fiscal 2000, approximately 36% of the Company's net sales were
derived from customers outside the United States, primarily in
Western Europe and the Far East (51% in fiscal 1999).  The decrease
in percentage of international sales is primarily due to the
acquisition and growth of the foundry business which has only U.S.
customers.  International sales represented 50% and 55% of net core
business sales in fiscal 2000 and 1999, respectively. All of the
Company's sales to international customers were denominated in U.S.
currencies.  There was no currency exchange exposure.

Gross Margin:  The Company's gross margin as a percentage of net
sales was 36.5% and 43.1%, in fiscal 2000 and 1999, respectively.
Gross margin for the current fiscal year was adversely affected by
the Company incurring additional overhead expenses as a result of
operating two fabs, including the depreciation of the capitalized
assets and the amortization of other assets associated with the new
fab.  Gross margin during fiscal 2000 was also affected by lower
margins associated with the foundry business resulting from the
acquisition of the Company's new fab.

Research and Development:  Research and development expenses, which
include payroll and benefits, processing costs and process transfer
costs, were 11.9% and 14.2% of net sales in fiscal 2000 and 1999,
respectively.  Dollar expenditures for research and development were
$8,468,000 and $7,195,000 for fiscal 2000 and 1999, respectively.
While the dollar expenditure for fiscal 2000 is higher than the
prior fiscal year, the growth in net sales caused the percentage of
research and development expense to net sales to decline. The
increase in research and development expenses is due to a non-
recurring payment of $1,350,000 to Orbit Semiconductor, Inc. under a
process development agreement to accelerate the process transfer of
Supertex's core products to the six-inch fab from the old four-inch
fab.

Selling, General and Administrative: Selling, general and
administrative expenses, which include commissions,

<PAGE>

payroll and benefits, were 9.9% and 13.6% of net sales in fiscal
2000 and 1999, respectively.  In fiscal 2000, the selling, general and
administrative expenses was $6,980,000 compared to $6,860,000 for
fiscal 1999.  While the selling, general and administrative expenses
remained relatively the same as the previous year, the increase in
net sales amount caused the percentage of selling, general and
administrative expenses as a percent of net sales to decrease 3.7%.

Interest Income:  Interest income, which consists primarily of
interest income from the Company's cash, cash equivalents and short-
term investments, was $1,978,000 in fiscal 2000 as compared with
$1,981,000 in fiscal 1999. The decrease in interest income was
caused by the decrease in cash available for investment due to the
purchase of the new fab.

Other Income:  Other Income of $257,000 for fiscal 2000 consists
primarily of gain on disposal of surplus equipment and sublease
expenses net of sublease income.  The increase in this category for
the fiscal 2000 when compared to fiscal 1999 was primarily due to
the gain on disposal of surplus equipment.

Provision for Income Taxes:  Income taxes for fiscal 2000 and 1999
were at 33.0% and 25.3%, respectively, of income before provision
for income taxes. The current fiscal year's tax provision is 33%
compared to a lower tax provision for fiscal 1999.  Higher tax
credits and additional expenses from the acquisition of the six-inch
fab caused fiscal 1999 tax rate to be significantly lower.

Fiscal 1999 VS Fiscal 1998

Net Sales:  The Company had net sales of $50,721,000 in fiscal 1999,
a decrease of $1,985,000 or 3.8% from the previous fiscal year.  The
decline in fiscal 1999 net sales reflects weakness in demand and
price pressure during the first three fiscal quarters primarily as a
result of the Asian economic crisis.

In fiscal 1999, approximately 51% of the Company's net sales were
derived from customers outside the United States, primarily in
Western Europe and the Far East (53% in fiscal 1998).  All of the
Company's sales to international customers were denominated in U.S.
currencies.  There was no currency exchange exposure; however,
during the first three quarters of fiscal 1999 when the US dollar
strengthened beyond expectation, many international customers
requested and received some modest price concessions.

Gross Margin:  The Company's gross margin as a percentage of net
sales was 43.1% and 45.5% in fiscal 1999 and 1998, respectively.
The decline in gross margin in fiscal 1999 is the result of the
decline in net sales as discussed above and increased manufacturing
depreciation expense partly due to the acquisition of the six-inch
submicron wafer fabrication facility.

Research and Development:  Research and development expenses were
14.2% and 10.6% of net sales in fiscal 1999 and 1998, respectively.
The increase in research and development expenses for fiscal 1999 is
attributable primarily to the Process Development Agreement ("PDA")
that the Company has with Orbit Semiconductor which will allow
faster process transfer from the Company's four inch fabrication
processes to the Company's newly acquired six inch submicron wafer
fabrication facility.  The PDA extends up to the first quarter for
fiscal 2000.

Selling, General and Administrative: Selling, general and
administrative expenses were 13.6% and 12.8% of net sales in fiscal
1999 and 1998, respectively.  In fiscal 1999, the selling, general
and administrative expenses remained relatively the same as the
previous year but the decline in net sales amount caused the
percentage to increase less than 1%.

Write-off of In-process Technology:  The Company incurred a non-cash,
non-tax deductible charge to operations of $2.5 million for the
write-off of in-process technology related to the acquisition of
assets from Orbit Technology in February 1999, because the
technological feasibility of the in-process technology acquired had
not been established and there was no alternative future use.

Interest Income:  Interest income, which consists primarily of
interest income from the Company's cash, cash equivalents and short-
term investments, was $1,981,000 as compared with $1,666,000 in
fiscal 1998 due to the

<PAGE>

larger amount of funds available for investment.

Other Income (Expense):  Other Income (expense) of $130,000 for
fiscal 1999 consists primarily of royalties received from Texas
Instruments net of tax, sublease income net of sublease expenses,
and gain on disposal of retired equipment.  The decline in this
category for the fiscal year 1999 when compared to fiscal 1998 was
primarily due to additional sublease expenses incurred during the
fiscal year, mainly depreciation in nature, as a result of a new
sublease contract.

Provision for Income Taxes:  Income taxes for fiscal 1999 and 1998
were at 25.3% and 34.0%, respectively, of income before provision
for income taxes.  The lower tax provision for fiscal 1999 was due
to higher tax credits and additional expenses from the acquisition
of the six-inch facility

Financial Condition

Overview:  Total assets grew to $86,623,000 at the end of fiscal
2000, up from $74,589,000 at the end of fiscal 1999.  The increase
was due primarily to profit generated from operations during the
year.

Liquidity and Capital Resources:  The Company's primary source of
funds for fiscal 2000, 1999, and 1998 has been the net cash
generated from operating activities of $9,022,000, $10,274,000, and
$10,864,000, respectively.  Net cash provided by operating
activities in fiscal 2000 of $9,022,000 consisted principally of net
income of $8,475,000, plus depreciation and amortization of
$6,118,000, provision for doubtful accounts and sales returns of
$3,150,000, income taxes payable of  $1,186,000, and an increase in
accounts payable and accrued expenses of $2,455,000, partially
offset by decreases in accounts receivable, deferred income taxes
and inventories of $6,718,000, $1,017,000, and $3,295,000,
respectively.

Net cash used in investing activities in fiscal 2000 was
$15,265,000, which consisted of increase in short term investments
of $11,385,000 and the purchase of property and equipment of
$3,880,000.

Net cash provided by financing activities in fiscal 2000 was
$637,000, which consisted of proceeds from exercises of stock
options of $1,602,000 partially offset by repurchases of the
Company's common stock in the amount of $965,000.

As of March 31, 2000, the Company's working capital was $52,950,000,
which included approximately $34,176,000 in cash, cash equivalents
and short-term investments.

The Company anticipates that the available funds and cash expected
to be generated from operations will be sufficient to meet cash and
working capital requirements through the end of fiscal 2000.  The
Company expects to spend approximately $7,000,000 for capital
acquisitions during fiscal 2001.

Year 2000 Issues.

We reviewed and tested our internal programs and noted no issues
relating to Year 2000. We have not experienced any problems with our
computer systems being unable to recognize appropriate dates related
to Year 2000. We are also not aware of any material problems with
our customers or suppliers. Accordingly, we do not anticipate
incurring material expenses or experiencing any material operational
disruption as a result of Year 2000 issues.

Recent Accounting Pronouncements

In June 1998, the FASB issued Statement of Financial Accounting
Standards No. 133, ("SFAS No. 133"), "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes new
standards of accounting and reporting for derivative instruments and
hedging activities. SFAS No. 133 requires that all derivatives be
recognized at fair value in the statement of financial position and
that the corresponding gains or losses be reported either in the
statement of operations or as a component of comprehensive income,
depending on the type of hedging relationship that exists. SFAS No.
133 is effective for fiscal years beginning after June 15, 2000.
Earlier application is allowed as of the beginning of any quarter
beginning after issuance. The

<PAGE>

Company does not anticipate that the adoption of SFAS 133 will have
a material impact on its financial position or results of operations.

In March 2000, The Financial Accounting Standards Board  ("FASB")
issued FASB interpretation No. 44 "Accounting for Certain
Transactions Involving Stock Compensation an interpretation of APB
Opinion No. 25".  This interpretation has provisions that are
effective on staggered dates, some of which began after December 15,
1998 and others that become effective after June 30, 2000.  The
adoption of this interpretation did not, and is not expected to have
a material impact on the financial statements.

Item 7A.   Quantitative and Qualitative Disclosures About Market
Risk

The Company is exposed to financial market risks due primarily to
changes in interest rates. The Company does not use derivatives to
alter the interest characteristics of its investment securities. The
Company has no holdings of derivative or commodity instruments. The
fair value of the Company's investment portfolio or related income
would not be significantly impacted by changes in interest rates
since the investment maturities are short and the interest rates are
primarily fixed. The Company anticipates interest income on cash
balances for FY2001 to be approximately $1,750,000 at an estimated
average interest rate of 5%.

                  REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and
Shareholders of Supertex, Inc.


In our opinion, the consolidated financial statements listed in the
index appearing under Item 14(a)(2) present fairly, in all material
respects, the financial position of Supertex, Inc. and its
subsidiary at March 31, 2000 and March 31, 1999, and the results of
their operations and their cash flows for each of the three years
in the period ended March 31, 2000, in conformity with accounting
principles generally accepted in the United States. In addition, in
our opinion, the financial statement schedule listed in the index
appearing under Item 14(a)(3) presents fairly, in all material
respects, the information set forth therein when read in
conjunction with the related consolidated financial statements.
These financial statements and financial statement schedule are the
responsibility of the Company's management; our responsibility is
to express an opinion on these financial statements and financial
statement schedule based on our audits. We conducted our audits of
these statements in accordance with auditing standards generally
accepted in the United States, which require that we plan and
perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by
management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities
at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period.  Actual results
could differ from those estimates.

Certain Risks and Uncertainties:  The Company's business is
concentrated in the high voltage semiconductor components industry,
which is rapidly changing, highly competitive and subject to
competitive pricing pressures.  The Company's operating results may
experience substantial period-to-period fluctuations due to these
factors, including the cyclical nature of the semiconductor
industry, the changes in customer requirements, the timely
introduction of new products, the Company's ability to implement new
capabilities or technologies, its ability to manufacture
efficiently, its reliance on subcontractors and vendors, and the
general economic conditions.

Cash and Cash Equivalents:  The Company considers all highly liquid
debt and equity instruments purchased with an original maturity of
three months or less to be cash equivalents.

Financial Instruments:   Short term investments, which are classified
as available-for-sale, consist principally of commercial paper that
matures within one year and are stated at fair market value, which
approximates cost.  Unrealized holding gains and losses are
reflected at a net amount as a separate component of the
shareholders' equity until realized.  For the purpose of computing
realized gains and losses, cost is identified on a specific
identification basis.

Investments in equity securities that are not traded on public
markets are accounted for under the cost method of accounting.  The
company periodically evaluates the carrying value of such equity
investments and when a decline in the value is other than temporary,
the securities are reduced to their net realizable value.  The
Company's  Supplemental Employee Retirement Plan has investments in
equity securities that are not publicly traded.

Concentration of credit risk and foreign operations:  Financial
instruments which potentially subject the Company to concentrations
of credit risk consists principally of cash and cash equivalents and
accounts receivable.  The Company's accounts receivable are derived
from revenue and earned from customers located in the U.S. and
certain foreign countries and regions, including Europe and Japan.
Sales to foreign customers for the year ended December 31, 1998,
1999 and 2000, all of which were denominated in U.S. dollars,
accounted for 53%, 51% and 36% of net sales, respectively.  The
Company performs ongoing credit evaluations of its customers'
financial condition and requires no collateral from its customers.
The Company maintains an allowance for doubtful accounts receivable
based upon the expected collectibility of accounts receivable.

The Company sells its semiconductor products in North America,
Europe and the Pacific Rim to numerous customers.  Allowances for
potential credit losses are maintained and such losses historically
have not been

      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

material.  Substantially all of the Company's cash, cash equivalents
and short term investments are held at four major financial
institutions domiciled in the United States.

Significant Customers:  During the year ended March 31, 2000, two
customers, Microtek and Dii Semiconductor, represented 10% and 17%
of gross accounts receivables, and 12% and 11% of net sales,
respectively.  Microtek also accounted for approximately 16%, and
19% of net sales in fiscal 1999, and 1998, respectively.

Inventories:  Inventories are stated at the lower of cost (determined
on a first-in, first-out basis) or market value.  The Company's
inventories include high technology parts and components that are
specialized in nature and subject to rapid technological
obsolescence.  While the Company has programs to minimize the
required inventories on hand and considers technological
obsolescence when estimating amounts required to reduce recorded
amounts to market values, it is reasonably possible that such
estimates could change in the near term.

Property, Plant and Equipment:  Property and equipment are stated at
cost and generally depreciated using accelerated methods over
estimated useful lives of five years.  Building and building
improvements are recorded at cost and are depreciated on a straight-
line basis over the useful life of the building.  Leasehold
improvements are recorded at cost and are amortized on a straight-
line basis over the lesser of the related lease term or the
estimated useful life of the assets.  The Company reviews for
impairment of its long-lived assets whenever events or changes in
circumstances indicate that the carrying amount of an asset might
not be recoverable.  In certain situations, an impairment loss would
be recognized.

Intangible Assets:  Intangible assets were recorded in conjunction
with the Asset Purchase Agreement with Orbit Semiconductor.  Other
intangible assets consist of purchased technology and assembled
workforce, which are being amortized on a straight-line basis over
their estimated useful lives of two years and five years,
respectively.

The Company assesses the recoverability of intangible assets by
determining whether the amortization of the asset's net book value
over its remaining life can be recovered through projected
undiscounted future cash flows.  Intangible assets consist of the
following at March 31, 2000 and 1999 (in thousands):

Revenue Recognition:  Net sales are stated net of discounts and
allowances.  Revenue from direct sales to end-user customers is
recognized upon shipment of product.  Sales to distributors are made
primarily under arrangements allowing limited price protection and
the right of stock rotation on merchandise unsold by the
distributors.  Because of the uncertainty associated with pricing
concessions and possible returns, the Company defers recognition of
such sales and the related costs of sales until the merchandise is
sold by distributors to their end-user customers.

Net Income per Share:  Basic earnings per share ("EPS") is computed
as net income divided by the weighted average number of common
shares outstanding for the period.  Diluted EPS reflects the
potential dilution that could occur from common shares issuable
through stock options, warrants, and other convertible securities.
The following is a reconciliation of the numerator (net income) and
the denominator (number of shares) used in the basic and diluted EPS
calculations.

respectively, were outstanding but were not included in the
computation of diluted earnings per share because the option
exercise prices were greater than the average market price of the
common stock.

Income Taxes:  The Company utilizes the liability method to account
for income taxes where deferred tax assets or liabilities are
determined based on the temporary differences between the bases used
for financial versus tax reporting of assets and liabilities, using
tax laws and rates in effect for the year in which the differences
are expected to affect taxable income.

Advertising Costs:  We expensed advertising and promotional costs as
they are incurred.  Advertising costs for the last three fiscal
years were immaterial.

Fair Value of Financial Instruments:  Carrying amounts of certain of
the Company's financial instruments including cash, cash
equivalents, accounts receivable, and accounts payable approximate
fair value due to their short maturities.

Comprehensive Income:  In fiscal 1999, the Company adopted SFAS No.
130, "Reporting Comprehensive Income." SFAS No. 130 establishes
standards for disclosure and financial statement display for
reporting total comprehensive income and its individual components.
Comprehensive income, as defined, includes all changes in equity
during a period from non-owner sources.  The Company's comprehensive
income includes net income and unrealized gains and losses on
investments and is displayed in the statement of stockholders'
equity,

Recent Accounting Pronouncements:  In June 1998, the FASB issued
Statement of Financial Accounting Standards No. 133, ("SFAS No.
133"), "Accounting for Derivative Instruments and Hedging
Activities." SFAS No. 133 establishes new standards of accounting
and reporting for derivative instruments and hedging activities.
SFAS No. 133 requires that all derivatives be recognized at fair
value in the statement of financial position and that the
corresponding gains or losses be reported either in the statement of
operations or as a component of comprehensive income, depending on
the type of hedging relationship that exists. SFAS No. 133 is
effective for fiscal years beginning after June 15, 2000. Earlier
application is allowed as of the beginning of any quarter beginning
after issuance. The Company does not anticipate that the adoption of
SFAS 133 will have a material impact on its financial position or
results of operations.

In March 2000, The Financial Accounting Standards Board  ("FASB")
issued FASB interpretation No. 44 "Accounting for Certain
Transactions Involving Stock Compensation an interpretation of APB
Opinion No. 25".  This interpretation has provisions that are
effective on staggered dates, some of which began after December 15,

4. ACQUISITION OF FACILITY (in thousands):

In February 1999, the Company acquired certain assets related to the
six-inch fabrication facility of Orbit Semiconductor for a total
cash purchase price of approximately $10,000,000 including direct
costs incurred. The acquisition of assets has been accounted for as
a purchase and the results of operations have been included in the
consolidated statement of operations of the Company from the date of
acquisition. The purchase price was allocated to assets acquired
based on fair value determined by independent appraisers. The
allocation of the purchase price was as follows (in thousands):

Property and equipment          $ 5,277
Purchased technology              1,735
Assembled workforce                 482
In-process technology             2,506
                                -------
                                $10,000
                                =======

The amounts allocated to purchased technology and assembled
workforce were determined through known valuation techniques in the
high technology industry.  The value assigned to in-process
technology was determined by identifying development projects for
which technological feasibility had not been established and
estimating the expected cash flows from the projects once
commercially feasible.  These cash flows were discounted back to
their present value and a percentage of completion discount was
applied to the calculation. The percentage of completion for the in-
process projects ranged from 50% to 90% complete, resulting in
estimated cost to complete of $7,000,000. The technological
feasibility of the in-process technology had not been established
and had no alternative future use.  Accordingly, the entire $2.5
million has been charged to operations in the fourth quarter of
fiscal 1999.

Management has determined that no valuation allowance is required
because, although realization is not assured, the Company has
sufficient taxable income in carryback years to absorb items
deductible in the future for federal tax purposes and anticipates
that its estimated future taxable income will allow the deferred tax
asset for state tax purposes to be fully realized in future years.
The amount of the deferred tax asset that is realizable could be
reduced in the near term if actual results differ significantly from
estimates of future taxable income.

6.   EMPLOYEE BENEFIT PLANS

Profit Sharing Plan  -- The Company has a discretionary profit
sharing plan for the benefit of eligible employees.  Related
expenses were $1,152,000, $914,000, and $1,299,000 in fiscal 2000,
1999, and 1998, respectively.

Savings and Retirement Plan  -- The Supertex Savings and Retirement
Plan allows for employee savings intended to qualify under the
provisions of Section 401 of the Internal Revenue Code.  Employees
having at least three months of permanent service may make pretax
contributions of 1% to 20% of qualified compensation, with the
Company matching certain percentages of employee contributions, all
of which are 100% vested.  In fiscal years 2000, 1999 and 1998, the
Company's matching contributions were $254,000, $189,000, and
$180,000, respectively.

Stock Option Plan  --  The 1991 Stock Option Plan (the Option Plan)
provides for granting incentive stock options to employees, and non-
statutory stock options to employees and consultants.  Terms for
exercising options are determined by the Board of Directors, and
options expire at the earlier of the term provided in the Notice of
Grant or upon termination of employment or consulting relationship.

A total of 2,825,715 shares of the Company's common stock were
reserved for issuance under the 1991 Plan. Options granted under the
Plan are granted at the fair market value of the Company's common
stock on the date of grant and generally expire 7 years from the
date of grant or at termination of service, whichever occurs first.
The options generally are exercisable beginning one year from date
of grant and generally vest over a five-year period.

Activity under the Option Plan is as follows (in thousands, except

</TABLE>

The weighted average fair value of options granted during fiscal
2000, 1999, and 1998 was $7.50 per share, $5.89 per share, and $4.94
per share, respectively.  All options were granted at market price
of the Company's common stock on the date of grant.  The Company
made option grants prior to fiscal 1996, the effective disclosure
date of SFAS 123.  Therefore, the pro forma disclosures may not be
representative of the effects on reported net income or earnings-per-
share for future years.

The fair value of each option grant for the Option Plan is estimated
on the date of grant using the Black-Scholes multiple options
pricing model with the following weighted average assumptions by
year:

Had compensation cost for the Option Plan been determined based on
the fair value at the grant date for the awards consistent with the
provisions of SFAS 123, the Company's net income and net income per
share for the years ended March 31, 2000, 1999 and 1998 would have
been reduced to the pro forma amounts indicated below (in thousands
except per share data):

7.COMMITMENTS AND CONTINGENCIES

Operating Leases

The Company leases its four-inch manufacturing facility under an
operating lease that expires in 2001, from a corporation owned by
one of the Company's directors.  Under the lease, the Company is
responsible for maintenance costs, including real property taxes,
utilities and other costs.  As part of the acquisition of the
Orbit's six inch wafer fabrication operation, the Company assumed an
operating lease for a manufacturing facility.  The lease expires on
April 30, 2004 with two (2) options to extend the term of the lease,
each for a
period of five (5) years.  Monthly rent during the entire term is
$68,000  which is adjusted annually based on Bureau of Labor
Statistic's Consumer Price Index.  The Company is responsible for
maintenance costs, including real property taxes, utilities,
insurance and other costs. In addition, following the acquisition of
the six inch wafer fabrication facility, the Company assumed an
existing equipment operating lease from Orbit Semiconductor.  This
operating lease consists of four different lease schedules
representing four groups of equipment. Operating lease expenses were
approximately $773,000 and $129,000 in fiscal years 2000 and 1999,
respectively.  Future minimum lease payments under all operating
leases at March 31, 2000 are as follows (in thousands):

                              Fiscal Year
               2001    2002    2003    2004    2005    Total
               ----    ----    ----    ----    ----    -----
            $ 1,788 $ 1,038 $   816 $   816 $    68 $  4,526

Future sublease income under all operating leases at March 31, 2000
are as follows:

                              Fiscal Year
               2001    2002    2003    2004    2005    Total
               ----    ----    ----    ----    ----    -----
            $  600  $   403      --      --      -- $  1,003

Facilities rental expenses, net of facilities sublease, were
approximately $944,000, $462,000, and $ 315,000 (net of facilities
sublease income of $260,000, $49,000, and $49,000) in fiscal years
2000, 1999, and 1998, respectively.  Of the total rental expenses
paid, $388,000, $375,000, and $362,000 were paid to the Company's
director in fiscal 2000, 1999, and 1998 respectively.

In addition to the foregoing, from time to time the Company is
subject to possible claims or assessments from third parties arising
in the normal course of business.  Management has reviewed such
possible claims and assessments with legal counsel and believes that
it is unlikely that they will result in a material adverse impact on
the Company's financial position or results of operations.
