Item 1.  Business

Supertex, Inc. ("Supertex" or the "Company") is a
technology-based, niche-oriented, producer of specialized
semiconductor components.  It designs, develops, manufactures,
and markets proprietary products utilizing state-of-the-art
DMOS, HVCMOS and HVBiCMOS technologies.  With respect to DMOS,
the Company has maintained an established position in key
products for commercial, industrial and military uses,
principally in small signal power MOSFETS.  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 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.  Supertex also maintains
three direct field offices located in: (1) Tallman, New York;
(2) Des Plaines, Illinois; and (3) South Wales, United Kingdom. 
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 facilitate the
interface between the low voltage computer logic signal world
and the high voltage requirements of the real world.  It
supplies standard and custom interface products for the
following three market groups:

(1) Telecommunications Group consists of interface products used 
in telephone handsets, solid state relays, modems, fax, ISDN,
networking, PABX, 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.

(2) 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 backlight displays of handheld instruments,
such as cellular phones, pagers, and meters. The printer product
family is used in ink-jet and electrostatic types of printers
and plotters which are mostly high end with full color high
resolution and high speed.

(3) Medical Electronics Group consists of products primarily for
ultrasound diagnostic imaging equipment as well as selected
portable instrumentation applications.

Because Supertex is a leading provider of products to these
specific markets, Supertex has 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 allowed its
customers to develop more quickly new and more advanced products
for their markets.

In the DMOS discrete transistor and array product line, Supertex
focuses on certain niches such as very low threshold devices
which are most suitable for telecommunication and hand held
applications where power costs are at a premium.

<PAGE>
Research and Development

Supertex expended approximately $5,306,000, $5,647,000, and
$4,427,000 on research and development activities during fiscal
years 1997, 1996, and 1995, respectively.  Research and
development activities continue at the rate of over thirty new
product projects per year.

Supertex believes that its position as a leading supplier in its
targeted markets can only be maintained through continuous
investments in research and development.  Supertex focuses its
efforts on designing new products with existing process
technologies while also developing new process technologies to
be used for future new products.  The effective  monitoring and
control of the Company's research and development programs have
actually resulted in better performance and greater
technological achievements.

Manufacturing

Manufacturing operations include wafer fabrication, limited
assembly and packaging, product testing, and quality control. 
The Company's wafer fabrication facilities are continually
upgraded to keep pace with technological developments, to
enhance environmental controls, and to improve technical
capabilities. To support growth, the Company anticipates
significant capital expenditures for equipment additions and
upgrades and for facility expansion in the near future.  In
addition, through a licensing agreement, Texas Instruments has
allocated a certain amount of its wafer capacity to Supertex to
supplement the Company's production needs. 

Supertex subcontracts most of its standard component packaging
to independent assemblers, principally in Thailand, Taiwan,
Malaysia, and the Philippines.  The Company tests all products
before shipment to customers.  The Company has experienced
increases in packaging and assembly costs in the past due to
fluctuations in the valuation of foreign currencies and
recognizes that future fluctuations could have a material
adverse impact on gross margins.  To date, however, the Company
has not experienced any materially adverse effects from these
fluctuations.  A specialized assembly area is maintained at the
Company's manufacturing facilities to package engineering
prototypes, to ensure high priority deliveries, and to assemble
high reliability circuits required in military and high
reliability applications.  Although the Company's off-shore
assembly subcontractors have not experienced any serious work
stoppage, the political situation in these countries could be
volatile.  Any prolonged work stoppage or other inability of the
Company to assemble products would have a material adverse
impact on the Company's operating results although the Company
has 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 the Company's operating results.

The availability of silicon wafers has improved considerably in
the past year.  Supertex, with several suppliers, has the wafer
supply capability to continue its operations. .  The Company has
also made arrangements with its major wafer supplier to
guarantee a continuous supply.  This agreement expires in July
2000.   Assembly packages and other raw materials used by the
Company in the manufacture of its products are obtainable from
several suppliers.  Such types of materials had been in short
supply in the past, but recently these materials appear to be
subject to competitive pricing pressure.  However, any future
shortage of supply would have a material adverse effect on the
operating  results of the Company.  As is typical in the
semiconductor industry, the Company must allow lead time in
ordering certain materials and services and often commits to
volume purchases to obtain favorable pricing concessions and
resource allocations.

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

<PAGE>
especially from the City of Sunnyvale, California, to ascertain 
that the Company is in compliance with present requirements.

Sales

Supertex markets its standard and custom products in the United
States and abroad through the Company's direct sales and
marketing personnel and through independent sales 
representatives and distributors supported by the Company's
field sales managers out of the Company's sales offices in
Illinois, New York, and the United Kingdom.  

Export sales are made primarily through independent distributors
to customers in Western Europe and the Far East, and represented
51%, 44%, and 50% of net sales in fiscal years 1997, 1996, and
1995, 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, the Company has not had any material adverse
effects on its business or financial results because of these
limitations.  

In fiscal 1997, one customer, a distributor, accounted for
approximately 18% of net sales.  In fiscal 1996, two customers
accounted for 15% and 12% of net sales.  In fiscal 1995, the
second customer discussed in the preceding sentence, accounted
for approximately 16% of net sales.  There is no long-term
production agreement with these customers.  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.

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 or 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.

Direct sales to customers are recognized upon shipment of
product.  Sales to distributors are made primarily under
arrangements allowing price protection and the right of stock
rotation on merchandise unsold by the distributors.  Because of
the uncertainty associated with pricing concessions and future
returns, the Company defers recognition of such sales and the
related costs of sales until the merchandise is sold by
distributors to end users.

Backlog

The Company's backlog at March 31, 1997, was approximately
$15,168,000 compared with $17,942,000 and $11,729,000 at March
31, 1996 and 1995, respectively.  Due to general industry
slowdown and high inventory, customers are demanding much
shorter lead times, resulting in smaller backlog.  The Company
expects that all of this backlog will be shipped in fiscal 1998.
 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, the
Company believes that backlog is not meaningful in predicting
the Company's actual net revenue for any future period.

Competition

Because of the Company's product niche orientation, market
statistics generally are not available for many of its products.
Competition in general among manufacturers of semiconductor
components and discrete transistors is intense.  Many of the
Company's domestic and foreign competitors have greater
facilities, financial, technical, and personnel resources, and
more diverse product lines.  Such factors as product prices,
product performance, diversity of product lines, delivery
capabilities, and the ability to adapt to rapid technological
change and develop new and improved products are the principal
methods of competition in the 

<PAGE>
industry.  The Company believes it is a leader in important 
segments of its product families where it has a technological 
and/or cost advantage and that it is generally competitive with 
respect to these factors.

Patents and Licenses

The Company holds numerous United States patents expiring from
1997 to 2009 and has applications for additional patents
pending.  Although the Company believes that its patents may
have value, there can be no assurance that the Company's
patents, or any additional patents that may be obtained in the
future, will provide meaningful protection from competition. The
Company believes that its success depends primarily on the
experience, creative skills, technical expertise, and marketing
ability of its personnel rather than on the ownership of
patents.  Patents may, however, be useful for cross license
purposes.

Supertex is not aware that any of its products infringe on
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, 1997, the Company had 316 full time employees. 
Many of the Company's employees are highly skilled, and the
Company's continued growth and success will depend in part on
its ability to attract and retain such employees, who are
generally in great demand.  At times, the Company as well as
other semiconductor manufacturers experience difficulty in
hiring and retaining sufficient numbers of skilled personnel.

The Company believes that the compensation, benefits, and
incentives offered to its employees are competitive with those
generally offered throughout the semiconductor industry.  There
are no collective bargaining agreements between the Company and
its 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

Certain Factors

This report contains forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933 and Section
21 E of the Securities Exchange Act of 1934.  Actual results
could differ materially from those projected in the
forward-looking statements as a result of the risk factors set
forth below and elsewhere in this report.  The industry in which
the Company competes is characterized by extreme rapid changes
in technology and frequent new product introductions.  The
Company believes that its long-term growth will depend largely
on its ability to continue to enhance existing products and to
introduce new products and features that meet the continually
changing requirements of customers.  While the Company has
invested heavily in new products and processes, there can be no
assurance that it can continue to introduce new products and
features on a timely basis or that certain of its products and
processes will not be rendered noncompetitive or obsolete by its
competitors.

The following discussion should be read in conjunction with the
"Consolidated Financial Statements," "Notes to Consolidated
Financial Statements" and "Selected Consolidated Financial Data"
included elsewhere in this Form 10-K.

Results of Operations

NET SALES.  The Company had net sales of $48,935,000 in fiscal
1997, an increase of $6,133,000 or 14% from the previous fiscal
year.  Fiscal 1996 net sales improved from fiscal 1995 by
$10,996,000 or 35%.  The Company's sales growth has been
generated principally by new product introductions in the
Company's targeted markets of medical ultrasound imaging,
telecommunications, and flat panel displays.

In fiscal 1997, approximately 51% of the Company's net sales
were derived from customers outside the United States, primarily
in Western Europe and the Far East (44% in fiscal 1996 and 50%
in fiscal 1995).  All of the Company's sales  to international
customers were denominated in U.S. currencies.  There was no
currency exchange exposure; however toward the end of the fiscal
1997 when the US dollar strengthened, many customers requested
and received price concessions.

GROSS MARGIN.  The Company's gross margin as a percentage of net
sales was 46.7%, 48.4%, and 49.3% in fiscal 1997, 1996, and
1995, respectively.  In fiscal 1997, production ramp up of newer
products, which have yet to benefit from production learning
curve efficiencies, contributed to the lower gross margins.  As
the Company gains production experience in these newer products,
gross margins are expected to improve.

RESEARCH AND DEVELOPMENT.  Research and development expenses were
10.8%, 13.2%, and 13.9% of net sales in fiscal 1997, 1996, and
1995, respectively.  The percentage decreases from year to year
were due to sales volume increases and tighter cost controls,
offset by increases in the number of projects in the last three
years.  The Company expects that research and development
projects will continue to increase during fiscal 1998.

SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and
administrative expenses were 12.7%, 13.3%, and 16.7% of net
sales in fiscal 1997, 1996, and 1995, respectively.  The
percentage decrease for each year was due to sales volume
increases, offset by actual dollar expense increases due to
increases in payroll and its related benefits, sales
commissions, and incentive compensation for certain sales
personnel.

INTEREST INCOME.  Interest income, which consists of interest
income from the Company's cash, cash equivalents and short-term
investments, was $1,430,000 as compared with $1,099,000 in
fiscal 1996 and $867,000 in fiscal 1995  primarily due to the
higher amount of funds available for investment. 

PROVISION FOR INCOME TAXES.  Income taxes for fiscal 1997, 1996,
and 1995 were at 32%, 31% and 27%, respectively, of income
before provision for income taxes.  The effective income tax
rate is expected to increase in fiscal 1998.

RECENT ACCOUNTING PRONOUNCEMENTS.  In February 1997, the
Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings Per Share"
(SFAS 128), which specifies the 

<PAGE>
computation, presentation and disclosure requirements for 
earnings per share.  SFAS 128 supersedes Accounting Principles 
Board Opinion No. 15 and is effective for financial statements 
issued for periods ending after December 15, 1997.  SFAS 128 
requires restatement of all prior-period earnings per share data 
presented after the effective date.  SFAS 128 will not have a 
material impact on the Company's financial position, results of 
operations or cash flows.

FINANCIAL CONDITION

OVERVIEW.  Total assets grew to $56,408,000 at the end of fiscal
1997, up from $45,428,000 at the end of fiscal 1996.  The
increase is due to favorable operating results for the year.

LIQUIDITY AND CAPITAL RESOURCES.  The Company's primary source of
funds for fiscal 1997, 1996, and 1995 has been the net cash
generated from operating activities of $8,524,000, $7,737,000,
and $3,767,000, respectively.  Net cash provided by operating
activities in fiscal 1997 of $8,524,000 consisted principally of
net income of $8,720,000 plus depreciation and amortization of
$2,163,000, provision for doubtful accounts and sales returns
$2,054,000 and an increase in accounts payable and accrued
expenses and deferred revenue of $1,284,000 and $344,000,
respectively, partially offset by increases in accounts
receivable and inventories of $3,641,000 and $2,251,000,
respectively.

Net cash used in investing activities in fiscal 1997 was
$5,668,000 which consisted of a decrease in short term
investments of $1,784,000 and purchases of property and
equipment of $7,452,000, which included the costs of upgrading
the Company's fabrication facility during the fiscal year.

Net cash provided by financing activities in fiscal 1997 was
$202,000, which consisted of proceeds from exercises of stock
options partially offset by repurchases of the Company's common
stock.

As of March 31, 1997, the Company's working capital was
$36,734,000, which included approximately $23,663,000 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 1998.  The Company expects to spend approximately
$6,362,000 for capital acquisitions during fiscal year 1998.

The Board of Directors and Shareholders of Supertex, Inc.:

 We have audited the consolidated financial statements and the
financial statement schedule of Supertex, Inc. and subsidiary
listed in Item 14(a) of this Form 10-K.  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 in accordance with generally accepted
auditing standards.  Those standards 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.  An
audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that
our audits provide a reasonable basis for our opinion.

 In our opinion, the financial statements referred to above
present fairly, in all material respects, the consolidated
financial position of Supertex, Inc. and subsidiary as of March
31, 1997 and 1996, and the consolidated results of their
operations and their cash flows for each of the three years in
the period ended March 31, 1997 in conformity with generally
accepted accounting principles.  In addition, in our opinion,
the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken
as a whole, presents fairly, in all material respects, the
information required to be included therein.

	 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Nature of Business.  The Company designs, manufactures and
markets custom and standard semiconductor products.

Use of Estimates in Preparation of the Financial Statements.  The
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 sales are
concentrated in the high voltage semiconductor components
industry, which is highly competitive and rapidly changing. 
Significant technological changes in the industry, changes in
customer requirements or the emergence of competitor products
with new capabilities or technologies could affect the Company's
operating results adversely.  The Company currently buys
substantially all of its silicon wafers, an integral component
of its products, from one supplier.  Failure by this supplier to
satisfy the Company's requirements on a timely basis at
competitive prices could cause a delay in manufacturing and a
possible loss of revenues, which would affect operating results
adversely.

Principles of Consolidation.  The consolidated financial
statements include the accounts of the Company and its
wholly-owned subsidiary.  All significant intercompany accounts
and transactions have been eliminated.

Net Sales.  The Company has no revenue-producing operations
outside the United States.  In fiscal 1997, one customer, a
distributor, accounted for approximately 18% of net sales.  In
fiscal 1996, two customers accounted for 15% and 12% of net
sales.  In fiscal 1995, the second customer discussed in the
preceding sentence, accounted for approximately 16% of net
sales.  Export sales, which are made primarily to Western Europe
and the Far East, accounted for approximately 51%, 44%, and 50%
of net sales in fiscal 1997, 1996 and 1995, respectively.

Fiscal Period  The Company uses a 52-53 week fiscal year ending
the Saturday nearest March 31.  The Company's fiscal years in
the accompanying financial statements have been shown ending on
March 31.  Fiscal years 1997, 1996, and 1995 all comprise 52
weeks.

Cash and Cash Equivalents.  The Company considers all highly
liquid debt instruments purchased with an original maturity of
three months or less to be cash equivalents.  The carrying
amounts reported in the balance sheets of cash, cash equivalents
and short term investments approximate estimated fair value
because of the short maturity of the financial instruments.

Short Term Investments.   Short term investments, which are
classified as held to maturity, consist principally of bank
certificates of deposit that mature within one year and are
stated at cost, which approximates fair market value.

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 or 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.

    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

Recent Accounting Pronouncements.  In February 1997, the
Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings Per Share"
(SFAS 128), which specifies the computation, presentation and
disclosure requirements for earnings per share.  SFAS 128
supersedes Accounting Principles Board Opinion No. 15 and is
effective for financial statements issued for periods ending
after December 15, 1997.  SFAS 128 requires restatement of all
prior-period earnings per share data presented after the
effective date.  SFAS 128 will not have a material impact on the
Company's financial position, results of operations or cash
flows.

Property and Equipment.  Property and equipment are stated at
cost and generally depreciated using accelerated methods over
estimated useful lives of five to thirty-nine years.  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.

Long-Lived Assets.  Effective April 1, 1996, the Company adopted
Statement of  Financial Accounting Standards No. 121 (SFAS 121),
"Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of," which requires the Company
to review for impairment of 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.  The adoption of SFAS 121
did not impact the Company's financial condition or results of
operations.

Revenue Recognition.  Direct sales to customers are recognized
upon shipment of product.  Sales to distributors are made
primarily under arrangements allowing price protection and the
right of stock rotation on merchandise unsold by the
distributors.  Because of the uncertainty associated with
pricing concessions and future returns, the Company defers
recognition of such sales and the related costs of sales until
the merchandise is sold by distributors to end users.

Net Income per Share.  Net income per share is computed using the
weighted average number of common and common equivalent shares
outstanding.  Common equivalent shares consist of outstanding
stock options.

Concentration of Credit Risk.  The Company sells its
semiconductor products in North America, Europe and the Pacific
Rim to numerous customers.  The Company performs ongoing credit
evaluations of its customers and generally does not require
collateral.  Allowances for potential credit losses are
maintained and such losses historically have not been material. 
Substantially all of the Company's cash, cash equivalents and
short term investments are held at three major banks domiciled
in the United States.

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.  The realizability of deferred tax assets is based on
expectations about future taxable income.

Stock Compensation.  Effective April 1, 1996, the Company adopted
Statement of Financial Accounting Standards No. 123 (SFAS 123),
"Accounting  for Stock-based Compensation," which requires the
Company to value stock-based compensation and to either record
the value in the financial statements or to disclose the impact
of the value and its impact on net income and earnings per share
in the footnotes to the financial statements.  The Company
elected the disclosure alternative and continues to account for
stock-based compensation using the intrinsic value method
prescribed by Accounting Principles Board No. 25, "Accounting
for Stock Issued to Employees."  Accordingly, the adoption of
SFAS 123 did not impact the Company's financial condition or
results of operations.

All of the Company's revenue is taxable in the
United States.  The provision for income taxes differs from the
amount computed by applying the statutory federal income tax
rate to income before provision for income taxes as follows:

						 1997      1996      1995
						 ----      ----      ----
Statutory provision ...........................   35%       34%       34%

						 ----      ----      ----
						  32%       31%       27%
						 ====      ====      ====

Income taxes of $4,265,000, $3,155,000, and $2,266,000 were paid
during fiscal 1997, 1996, and 1995, respectively.

  Total deferred tax assets ........................... $ 1,834   $ 1,241
							  =====     =====

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.

5.      EMPLOYEE BENEFIT PLANS

Profit Sharing Plan  --  The Company has a discretionary profit
sharing plan for the benefit of eligible employees.  Related
expenses were $1,259,000, $1,040,000, and $652,000 in fiscal
1997, 1996, and 1995, 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 1997, 1996, and 1995, the Company's matching contributions
were $160,000, $221,000, and $138,000, 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 1,925,715 shares of the Company's common stock were
reserved for issuance under the 1991 Plan.  As of March 31,
1997, 183,790 options were exercisable at a weighted average
exercise price of $5.00.  As of March 31, 1996, 123,530 options
were exercisable at a weighted average exercise price of $3.97.
As of March 31, 1995, 47,120 options were exercisable at a
weighted average exercise price of $3.34.  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.

</TABLE>

Stock Compensation -- The Company has adopted the
disclosure-only provisions of SFAS 123. Accordingly, no
compensation cost has been recognized for the 1991 Stock Option
Plan.  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,
1997 and 1996 would have been reduced to the pro forma amounts
indicated below (in thousands except per share data):

						1997    1996
					       ------  ------
		 Net Income    As reported     $8,720  $7,391 

			       Pro forma       $8,002  $7,032 

	 Earnings per share    As reported     $ 0.70  $ 0.60 

			       Pro forma       $ 0.65  $ 0.58 


The weighted average fair value of options granted during
fiscal 1997 was $6.87 per share.  The weighted average fair

value of all options granted during fiscal 1996 was $4.46 per 
share.  All options were granted at the market price of the 
Company's common stock on the date of grant.  The proforma 
disclosures may not be representative of the effects on reported 
net income or earnings-per-share for future years because options 
vest over several years and additional awards generally are made 
each year.

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:

						       1997    1996 
						       ----    ----
	   Risk-free interest rate ..................  5.53%   5.53%
