         NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                            (unaudited)

Note 1 - Basis of Presentation

In the opinion of management, the unaudited condensed consolidated financial
statements for the three and nine months ended December 31 , 2000 and 1999
include all adjustments (consisting of normal recurring adjustments)
necessary for fair presentation of financial condition and results of
operations for those periods in accordance with generally accepted
accounting principles.

The year-end condensed balance sheet data was derived from audited financial
statements, but does not include all disclosures required by generally
accepted accounting principles.  These financial statements should be read
in conjunction with the audited financial statements of Supertex, Inc. for
the fiscal year ended March 31, 2000, which were included in the Annual
Report on Form 10-K (File Number 0-12718).

Interim results are not necessarily indicative of results for the full
fiscal year.  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 as well as the reported amounts of revenue
and expenses during the reporting period. Actual results could differ from
those estimates, and such differences may be material to the financial
statements.

Note 2 - Inventories

Inventories consisted of (in thousands):

Note 3 - 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.  A reconciliation of the numerator and denominator of basic and
diluted earnings per share is provided as follows (in thousands, except per
share amounts).

Note 5 - 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
FIN 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 have a material impact on the
company's financial position or results of operations.

In December, 1999, SAB 101 was issued which summarizes the SEC's views in
applying generally accepted accounting principles to revenue recognition in
financial statements. In June, 2000 SAB 101B was issued to delay the
implementation of SAB 101 until the fourth quarter of fiscal year 2001. The
Company is currently evaluating the impact SAB 101 will have on its
financial position and results of operations.

Results of Operations

Net Sales  Net sales for the quarter ended December 31, 2000 were $20,209,000,
a 14% increase compared to $17,709,000 for the same quarter last year.  Net
sales for the nine months ended December 31, 2000 were $65,025,000, a 28%
increase compared to $50,743,000 for the same period of the prior fiscal
year. The increase in sales for the quarter and year-to-date period are
primarily due to increased unit sales volume of both core and foundry
products.

As percentage of total sales for the quarter ended December 31, 2000 and
1999, sales to customers in the medical electronics and telecommunications
markets represented 37% and 28% of total sales, respectively.  Sales to
customers in the imaging market was 24% in 2000 compared with 23% in 1999.
Sales to all other markets represented 11% in 2000 and 12% in 1999,
respectively.

As percentage of total sales for the nine months ended December 31, 2000,
sales to customers in the medical electronics market represented 36% of our
business as compared with 35% for the same period in 1999.  Sales to
customers in the telecommunications market was 27% in 2000 compared with 29%
in 1999.  Sales to customers in the imaging market was 25% in 2000 compared
with 23% in 1999.  Sales to all other markets represented 12% in 2000
compared with 13% in 1999. On a dollar basis, sales of our medical
electronics products increased 31% to $23,314,000 for the nine months ended
December 31, 2000, sales of our telecommunication products increased 19% to
$17,570,000, and sales of our imaging products increased 39% to $16,472,000.

Approximately 38% of the Company's net sales for this quarter and 40% for
the nine-month period ended December 31, 2000, were derived from
international customers as compared to 39% and 36% for the respective
periods in the prior year.  Although dollar sales to international customers
increased from quarter to quarter, the percentage of international sales to
total sales is slightly lower primarily due to lower demand in Japan.  For
the nine-month period, the increase in percentage of international sales is
primarily due to the increased sales volume in both Europe and Asia

Gross Profit  As a percent of sales, the Company's gross margin for the
three-month and nine-month periods ended December 31, 2000 were 42% and 41%
respectively, compared with 38% and 36% for the same periods of the last
fiscal year. The improvement in gross margin is primarily due to higher
production volume in our new six-inch fab operation, allowing us to benefit
from economies of scale.

Research and Development  Research and development (R&D) expense increased
93% to $3,054,000 for the quarter ended December 31, 2000 as compared to
$1,583,000 for the same quarter of the prior year. For the nine months ended
December 31, 2000, R&D expense increased 30% to $7,996,000 from $6,143,000
for the same period last year, with most of the increase occurring during
this past quarter. The increase in R&D expense for the three-month and
nine-month periods this year as compared to last year was due to an
increases in payroll expense resulting from additional headcount, and in
new product development efforts, as well as the transfer of our products
from four-inch to six-inch fab. Our customers have continued to worked with
us in our development efforts in the new integrated circuits (ICs) to drive
the optical micro-electro-mechanical systems (MEMS) and in the network power
interface circuits to drive photonic and gigabit Ethernet modules and voice
over Internet Protocol (VoIP) telephone systems.

Selling, General and Administrative  Selling, general and administrative
expense was $2,568,000 or 13% of net sales for the quarter ended December
31, 2000 as compared with $1,939,000 or 11% of net sales in the same quarter
of the prior year.  For the nine months ended December 31, 2000, selling,
general and administrative expense was $7,768,000 or 12% of net sales
compared to $5,044,000 or 10% for the same period last year.  The dollar
increases in selling, general and administrative expense for the three-month
period were primarily due to salary adjustments of $227,000, consulting fees
of $127,000, and commissions of $100,000.  The dollar increases for the
nine-month period were due to salary adjustments of $877,000, bad debt
expense of $518,000 and sales commissions of $600,000, consulting fees of
$175,000, depreciation of $155,000 and data processing expenses for software
implementation of $154,000.

Interest and Other Income  Interest and other income, net for the three and
nine month periods ended December 31, 2000 was $512,000 and $2,250,000,
respectively.  For the three and nine month periods ended December 31, 1999,
interest and other income, net was $526,000 and $1,177,000, respectively.
The increase for the nine-month period was due to a $776,000 gain from
disposal of assets including retired equipment from the four-inch
fabrication plant and a $544,000 increase in interest income attributed to
larger average cash and investment balances.

Provision for Income Taxes  The Company's effective tax rate for the three
and nine months ending December 31, 2000 was 34% compared to 33%  for the
same periods of the last fiscal year.

Overview of Change in Financial Condition  Total assets increased to
$98,491,000 as of December 31, 2000, up from $86,623,000 at the end of last
fiscal year ended March 31, 2000.  The increase is due  primarily to
favorable operating results during the first nine months of the fiscal year.

Liquidity and Capital Resources  On December 31, 2000, the Company had
$41,304,000 in cash, cash equivalents, and short-term investments, compared
with $34,176,000 on March 31, 2000.  This increase is due primarily to
positive cash flow from operating activities of $11,682,000 consisting
principally of net income of $8,780,000.

Positive factors contributing to cash flow from operating activities are as
follows:
*    There was decrease in inventory of $865,000 primarily caused by the
increase in net sales.
*    There was an increase in income taxes payable of  $1,157,000 due to a
higher amount of income subject to tax and a higher tax rate.
*    There was an increase in trade accounts payable and accrued expenses
of $520,000 resulting from normal operating activities.
*    There was an increase in deferred revenue from a licensing agreement
of $400,000.

Meanwhile, negative factors affecting operating cash flow were as follows:
*    There was increase in accounts receivable of $3,661,000 primarily
caused by the increase in net sales.
*    There was an increase in prepaid expenses and other assets of
$1,317,000 relating primarily to a prepaid software maintenance contract
of $705,000; an increase in non-trade receivables from sale of surplus
four-inch equipment of $381,000; and increased accrued interest income of
$110,000.

Net cash used in investing activities during the nine-month period was
$16,725,000 of which $11,048,000 was used for short-term investments,
$4,888,000 was used to purchase property and equipment offset by proceeds
from disposal of surplus equipment of $961,000, and $1,750,000 was used to
purchase long-term investments in LightConnect, Inc. and OEpic Inc.

Net cash provided by financing activities during the nine-month period was
$1,123,000 all of which was generated from stock option exercises.

The Company anticipates that available funds and expected cash to be
generated from operations will be sufficient to meet cash and working
capital requirements through at least the next twelve months.
