            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 quarters ended September 30, 2001 and 2000 include all
adjustments (consisting of normal recurring adjustments) necessary for fair
presentation of the consolidated financial condition, results of operations,
and cash flows 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 Financial Accounting
Standards Board (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, 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 expects
to adopt FAS 142 effective April 1, 2002.  The Company has determined that the
adoption of FAS 142 will not have a material impact on its results of
operations and financial position.

In June 2001, the FASB issued FASB Statement No. 143 (FAS 143), "Accounting
for Asset Retirement Obligations".  FAS 143 requires that the fair value of a
liability for an asset retirement obligation be realized in the period which
it is incurred if a reasonable estimate of fair value can be made.  Companies
are required to adopt FAS 143 for fiscal years beginning after June 15, 2002,
but early adoption is encouraged.  The Company has not yet determined the
impact this standard will have on its financial position and results of
operations, although it does not anticipate that the adoption of this standard
will have a material impact on the Company's financial position or results of
operations.

In August 2001, the FASB issued FASB Statement No. 144 (FAS 144). "Accounting
for the Impairment or Disposal of Long-lived Assets". FAS 144 supercedes FASB
Statement No. 121, Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of, and the accounting and reporting
provisions of APB Opinion No. 30, Reporting the Results of Operations --
Reporting the Effects of Disposal of a Segment of a Business, and
Extraordinary, Unusual and Infrequently Occurring Events and Transactions, for
the disposal of a segment of a business (as previously defined in that
Opinion).  This Statement also amends ARB No. 51, Consolidated Financial
Statements, to eliminate the exception to consolidation for a subsidiary for
which control is likely to be temporary.  Companies are required to adopt FAS
144 for fiscal years beginning after December 15, 2001, and interim periods
within those fiscal years, but early adoption is encouraged.  The Company has
not yet determined the impact this standard will have on its financial
position and results of operations, although it does not anticipate that the
adoption of this standard will have a material impact on the Company's
financial position or results of operations.

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 September 30, 2001 were
$14,243,000, a 37% decrease compared to $22,512,000 for the same quarter last
year.  Net sales for the six months ended September 30, 2001 were $29,324,000,
a 35% decrease compared to $44,815,000 for the same period of the prior fiscal
year. Sales for the second quarter were adversely affected by the decline in
the telecommunications infrastructure spending and general economic slowdown
with weakness in all the markets we serve.  Many of our customers reduced
their demands for our component products as they face slower customer orders
and rising inventory levels.

As a percentage of total sales for the quarter ended September 30, 2001, sales
to customers in the medical electronics, imaging, and telecommunications
markets represented 38%, 30%, and 22% of total sales, respectively, compared
to 38%, 26% and 25% of total sales for the quarter ended September 30, 2000.
Sales to customers in other markets for the quarter ended September 30, 2001
was 10% of total sales, compared to 11% of the same period of last fiscal
year.

Approximately 27% of the Company's net sales for the quarter ended
September 30, 2001 and 28% for the six-month period ended September 30, 2001
were derived from international customers as compared to 41% and 40% of the
same periods of 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 was 40% for
the three-month  and six-month periods ended September 30, 2001 compared with
42% and 41% for the respective periods in the prior 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 8%
to $2,706,000 for the quarter ended September 30, 2001 as compared to
$2,512,000 for the same quarter of the prior fiscal year.  For the six months
ended September 30, 2001, research and development increased 21% to $5,976,000
from $4,942,000 for the same period last year.  The increase in R&D expense in
absolute dollars as well as in percentage of sales 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 three and six-month periods ended September 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
expense (SG&A) was $1,905,000 or 13% of net sales for the quarter ended
September 30, 2001 as compared with $2,920,000 or 13% of net sales in the
same quarter of the prior fiscal year.  For the six months ended
September 30, 2001, selling, general and administrative expense was
$3,721,000 or 13% of net sales compared to $5,200,000 or 12% for the same
period of the prior fiscal year. In absolute dollars, SG&A expenditures for
the three-month period decreased by 35% when compared to the same period in
the prior fiscal year primarily due to a reduction in sales commissions of
$184,000 attributed to a declining sales, a drop in provision for bad debts of
$296,000 and a decrease in labor costs and related benefits of $420,000 due to
a reduction in headcount.  For the six-month period, the reduction in SG&A
dollar expenditures when compared to the same period in the prior fiscal year
was due to a reduction in sales commissions of $340,000, a reduction in the
provision for bad debts of $606,000, and a decrease in labor costs and
related benefits of $322,000 due to a reduction in headcount.

Income from Operations  Income from operations was $1,127,000, or 8% of net
sales for the quarter ended September 30, 2001 compared to $4,062,000, or 18%
of net sales for the quarter ended September 30, 2000. For the six months
ended September 30, 2001, income from operations was $1,931,000 or 7% of net
sales, compared to $8,266,000 or 18% of net sales for the same period of the
prior fiscal year.  The decrease in operating income as a percentage of sales
is attributable to the increase in research and development expense at a time
of declining sales.

Interest and Other Income  Interest and other income, net for the three-month
and six-month periods ended September 30, 2001, were $589,000 and $1,492,000,
respectively. For the three-month and six-month periods ended September 30,
2000, interest and other income were $1,246,000 and $1,737,000, respectively.
The decrease in other income compared with the same period of prior fiscal
year is primarily due to a decrease in proceeds from disposal of surplus
equipment and lower yields on cash deposit accounts.

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

Liquidity and Capital Resources  On September 30, 2001, the Company had
$48,504,000 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 $5,025,000 consisting principally of net income of
$2,259,000 and non-cash charges for depreciation and amortization of
$1,801,000. Factors affecting cash flow from operating activities include
(a) a decrease in accounts receivable of $857,000 with a corresponding
reduction in the provision for doubtful accounts and sales return of
$405,000 largely due to lower sales; (b) an increase in deferred revenue of
$604,000, of which $425,000 is derived from a technology licensing agreement;
and (c) a decrease in accounts payable and other accrued items of $1,435,000
due to a decrease in purchasing activities.


Net cash used in investing activities during the six-month period was
$1,097,000 of which $1,724,000 was used to purchase equipment for the wafer
fab and testing operations offset in part by $627,000 provided by the proceeds
from the sale of long-term investments in Galleon New Media Funds.

Net cash provided by financing activities for the six-month period was
$294,000 generated by proceeds from the issuance of common stock through the
exercise of employee stock options of $226,000, and by proceeds from the
issuance of common stock through the Employee Stock Purchase Plan of $384,000.
This amount was offset by our 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.

Item 2. - Quantitative and Qualitative Disclosures About Market Risk and
Interest Rate Risk.

Interest Rate Sensitivity  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.  As of September 30,2001, the Company maintained its funds primarily
in money market funds and it plans to continue to invest a significant portion
of its existing cash in interest bearing money market funds and other
short-term debt securities with maturities of less than a year.
