             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 quarter ended June 30, 2001 and 2000 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 accounting principles generally accepted in the
United States of America.

The year-end condensed balance sheet data was derived from audited financial
statements, but does not include all disclosures required by accounting
principles generally accepted in the United States of America.  These
financial statements should be read in conjunction with the audited
consolidated financial statements of Supertex, Inc. for the fiscal year ended
March 31, 2001, 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 accounting
principles generally accepted in the United States of America 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 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).

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 adopted SFAS
No. 133 effective April 1, 2001.  The adoption of SFAS 133 did not have a
material impact on the Company's financial position or results of operations.

In July 2001, the Financial Accounting Standards Board (FASB) issued FASB
Statements Nos. 141 and 142 (FAS 141 and FAS 142), "Business Combinations"
and "Goodwill and Other Intangible Assets."  FAS 141 replaces APB 16 and
eliminates pooling-of-interests accounting prospectively.  It also provides
guidance on purchase accounting related to the recognition of intangible
assets and accounting for negative goodwill.  FAS 142 changes the accounting
for goodwill from an amortization method to an impairment-only approach.
Under FAS 142, goodwill will be tested annually and whenever events or
circumstances occur indicating that goodwill might be impaired.  FAS 141 and
FAS 142 are effective for all business combinations completed after June 30,
2001.  Upon adoption of FAS 142, amortization of goodwill recorded for
business combinations consummated prior to July 1, 2001 will cease, and
intangible assets acquired prior to July 1, 2001 that do not meet the
criteria for recognition under FAS 141 will be reclassified to goodwill.
Companies are required to adopt FAS 142 for fiscal years beginning after
December 15, 2001, but early adoption is permitted.  The Company will adopt
FAS 142 on April 1, 2002, the beginning of fiscal 2002.  In connection with
the adoption of FAS 142, the Company will be required to perform a
transitional goodwill impairment assessment.  The Company has not yet
determined the impact these standards will have on its results of operations
and financial position.

Cautionary Statement Regarding Forward Looking Statements This 10-Q 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. An
example of such a statement in this 10-Q is that the Company anticipates
available funds and expected cash generated from operations to be sufficient
to meet cash and working capital requirements through at least the next
twelve months. This statement is only a prediction, is not a guaranty of
future performance, and is 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 from those expressed or
forecasted in the forward-looking statements.  These risks and uncertainties
include those described in "Risk Factors" under Item 7, "Management's
Discussion and Analysis of Financial Condition and Results of Operation" in
our Annual Report of Form 10-K for the fiscal year ended March 31, 2001.
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.

Overview

Supertex designs, develops, manufactures, and markets high voltage analog and
mixed signal integrated circuits utilizing state-of-the-art high voltage
DMOS, HVCMOS and HVBiCMOS analog and mixed signal technologies.  We supply
standard and custom interface products primarily for use in the
telecommunications, imaging, and medical electronics markets.  We also
provide wafer foundry services for the manufacture of integrated circuits for
customers using customer-owned designs and mask toolings.

Results of Operations

Net Sales  Net sales for the quarter ended June 30, 2001 were $15,081,000, a
32% decrease compared to $22,303,000 for the same quarter last year.  Sales
for the first quarter was adversely affected by the decline in the
telecommunications infrastructure spending and general economic slowdown with
weakness in all the markets we serve.  Our customers reduced their demands
for our component products as they face slower customer orders and rising
inventory levels.

As percentage of total sales for the quarter ended June 30, 2001, sales to
customers in the medical electronics, imaging, and telecommunications markets
represented 37%, 28%, and 22% of total sales, respectively, compared to 35%,
29% and 23% of total sales for the quarter ended June 30, 2000.  Sales to
customers in other markets remained unchanged at 13% of total sales.

Approximately 28% of the Company's net sales for this quarter were derived
from international customers as compared to 39% of the same quarter last
year.  The decrease in international sales resulted from decreased shipments
to our customers in Asia and Europe primarily due to the sharp decline of
orders from contract manufacturers in Asia and the lack of telecommunications
infrastructure spending.

Gross Profit  As a percent of sales, the Company's gross profit for the
quarter ended June 30, 2001 was 39%, compared with 40% for the same period of
the last fiscal year.   Rigorous cost reduction measures allowed the Company
to quickly lower manufacturing expenditures to adjust to a much lower sales
level thereby retaining the gross profit percentage to sales.

Research and Development  Research and development (R&D) expense increased
35% to $3,270,000 for the quarter ended June 30, 2001 as compared to
$2,430,000 for the same quarter of the prior fiscal year.  The increase in
R&D expense in absolute dollars is primarily due to the Company's continued
development efforts in new integrated circuits (ICs) to drive the optical
micro-electro-mechanical systems (MEMS) and in network power interface
circuits to drive photonic and gigabit Ethernet modules and voice over
Internet Protocol (VoIP) telephone systems.   The increase in R&D expenses
in the quarter ended June 30, 2001 included labor costs for additional
headcount, rent, purchases of mask toolings, and data processing costs to
support new product development activities in our design centers.

Selling, General and Administrative  Selling, general and administrative
expenses (SG&A) were $1,816,000 or 12% of net sales for the quarter ended
June 30, 2001 as compared with $2,280,000 or 10% of net sales in the same
quarter of the prior year.  In absolute dollars, SGA expenditures for the
three-month period decreased by 20% when compared to the same period in
fiscal 2001 due to reduced sales commissions, and lower provision for bad
debts.  As a percentage of sales, SG&A expenses increased due to the lower
sales level.

Income from Operations  Income from operations was $804,000, or 5% of net
sales, for the quarter ended June 30, 2001 compared to $4,204,000, or 19% of
net sales for the quarter ended June 30, 2000. The decrease in operating
income as a percentage of sales was attributed to the increase in research
and development expenses at a time when sales declined and the fact that our
selling, general, and administrative expenses decreased at a slower rate than
the decline in sales.

Interest and Other Income  Interest and other income, net for the quarter
ended June 30, 2001, was $903,000 as compared to $491,000 of the same period
of prior fiscal year.  The increase was attributed to the gain from the
liquidation of a long-term investment of $127,000 and fees charged to
customers for returning products of $160,000.  Compared to the same period
last year, the interest income from short-term investments remained constant
as the slight increase in the average cash balance was offset by a decline in
interest rates.

Provision for Income Taxes The Company's effective tax rate for the three
months ending June 30, 2001 remained unchanged at 34%.

Liquidity and Capital Resources  On June 30, 2001, the Company had
$46,230,000 in cash and cash equivalents, compared with $44,282,000 on March
31, 2001.  This increase is due primarily to a positive cash flow from
operating activities of $1,273,000 consisting principally of net income of
$1,127,000 and non-cash charges for depreciation and amortization of
$899,000.

Net cash provided by operating activities for the quarter ended June 30, 2001
was positively impacted by an increase in income tax payable of $577,000 and
an increase in deferred revenue of $641,000.

Net cash provided by operating activities for the quarter ended June 30, 2001
was adversely impacted by an increase in accounts receivable of $667,000 and
a decrease in accounts payable and other accrued items of $1,827,000.

The Company's investment activities during the quarter ended June 30, 2001
generated cash of $442,000 as compared to $17,082,000 of cash used for
investment activities during the comparable period in the prior year.  Cash
generated by investment activities during the quarter ended June 30, 2001
resulted from the proceeds of the sale of long-term investments in Galleon
New Media Funds of $627,000, which was offset by purchases of equipment of
$185,000 primarily for wafer fab and testing operations.

The Company's financing activities during the quarter ended June 30, 2001
generated cash of $233,000 as compared to cash generated of $435,000 during
the comparable period in the prior year. Cash generated by financing
activities during the quarter ended June 30, 2001 was the result of $165,000
in proceeds from the issuance of common stock through the exercise of
employee stock options, and $384,000 in proceeds from the issuance of common
stock through the Employee Stock Purchase Plan.  This amount was offset by
the use of cash for the repurchase of 25,000 shares of common stock for
$316,000 as authorized by the Company's Stock Repurchase Program.

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.

Recent Accounting Pronoucements  In July 2001, the Financial Accounting
Standards Board (FASB) issued FASB Statements Nos. 141 and 142 (FAS 141 and
FAS 142), "Business Combinations" and "Goodwill and Other Intangible Assets."
FAS 141 replaces APB 16 and eliminates pooling-of-interests accounting
prospectively.  It also provides guidance on purchase accounting related to
the recognition of intangible assets and accounting for negative goodwill.
FAS 142 changes the accounting for goodwill from an amortization method to an
impairment-only approach.  Under FAS 142, goodwill will be tested annually
and whenever events or circumstances occur indicating that goodwill might be
impaired.  FAS 141 and FAS 142 are effective for all business combinations
completed after June 30, 2001.  Upon adoption of FAS 142, amortization of
goodwill recorded for business combinations consummated prior to July 1, 2001
will cease, and intangible assets acquired prior to July 1, 2001 that do not
meet the criteria for recognition under FAS 141 will be reclassified to
goodwill.  Companies are required to adopt FAS 142 for fiscal years beginning
after December 15, 2001, but early adoption is permitted.  The Company will
adopt FAS 142 on April 1, 2002, the beginning of fiscal 2002.  In connection
with the adoption of FAS 142, the Company will be required to perform a
transitional goodwill impairment assessment.  The Company has not yet
determined the impact these standards will have on its results of operations
and financial position.
