	    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1
------
In the opinion of management, the unaudited financial statements
for the six months ended September 30, 1997, 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, 1997, 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.

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.

In June 1997, the Financial Accounting Standards Board issued
Statement of  Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" (SFAS 130).  SFAS 130 establishes
standards for reporting and display of comprehensive income and
its components in a full set of general-purpose financial
statements.  Comprehensive income is defined as "the change in
equity of a business enterprise during a period from
transactions and other events and circumstances from nonowner
sources.  It includes all changes in equity during a period
except those resulting from investments by owners and
distributions to owners."  SFAS 130 is effective for fiscal
years beginning after December 15, 1997, and reclassification of
financial statements for earlier periods provided for
comparative purposes is required.  SFAS 130 is not expected to
have a material impact on the Company's financial position,
results of operations or cash flows.
<PAGE>

In June 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related
Information" (SFAS 131).  SFAS 131 establishes standards for the
way that public business enterprises report information about
operating segments in annual financial statements and requires
that those enterprises report selected information about
operating segments in interim financial reports issued to
shareholders.  SFAS 131 generally supersedes Statement of
Financial Accounting Standards No. 14, "Financial Reporting for
Segments of a Business Enterprise."  Under SFAS 131, operating
segments are components of an enterprise about which separate
financial information is available that is evaluated regularly
by the chief operating decision maker in deciding how to
allocate resources and in assessing performance.  Generally,
financial information is required to be reported on the basis
that it is used internally.  SFAS 131 is effective for financial
statements for periods beginning after December 15, 1997, and
restatement of comparative information for earlier years is
required.  However, SFAS 131 is not required to be applied to
interim financial statements in the initial year of application.
SFAS 131 will not have a material impact on the Company's
financial position, results of operations or cash flows.  

PART I - FINANCIAL INFORMATION

Item 2 - 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, as well as timely capacity
expansions.  While the Company has invested heavily in new
products, new processes and new capacities, there can be no
assurance that it can continue to introduce new products, new
processes and new capacities on a timely basis or that certain
of its products, processes and capacities will not be rendered
noncompetitive or obsolete by its competitors.

Results of Operations

Net Sales:  Net sales for the second quarter ended September 30,
1997 increased 5% to $13,613,000 from $12,920,000 of the same
quarter last year.  Six months net sales of $25,925,000
increased 2% from the same period last year of $25,381,000. 
Continued strength in our customers' markets contributed to this
increase in sales.  During the six months ended September 30,
1997, approximately 52% of Supertex's shipments were to
international customers.

Gross Margin:  Gross margin for the second quarter and six months
ended September 30, 1997 were 45% compared with 49% for the same
quarter and six months period of the prior year.  The decrease in
gross margin is a result of the change in product mix toward less
mature products which caused the Company to incur higher 
engineering support costs.  In order to meet its product demand, 
the Company is in the 
<PAGE>

process of completing its wafer fabrication facility upgrades, 
and additional maintenance and support costs were incurred.

Research and Development:  As a percentage of net sales, R&D
expenses increased to 10.5% and 10.8% of net sales for the 
quarter and six months ending September 30, 1997, respectively.  
This compares with R&D expense of 9.5% and 10% of net sales for 
the quarter and six months period of last year.  Dollar 
expenditures also increased to $1,425,000 for the three months 
($2,801,000 for six months) ended September 30, 1997 versus 
$1,223,000 for three months ($2,534,000 for six months) 
corresponding periods of last year.  The Company expects that
research and development expenses will increase during the
remainder of this fiscal year.

Selling, General and Administrative:  Selling, general and
administrative expenses for the second quarter and six months
ended September 30, 1997 and for the corresponding periods of the 
prior fiscal period were 12% of net sales.  Fixed costs remained 
fairly constant from year to year in this category, with sales 
commissions increases in line with increased sales.

Interest and Other Income:  Interest and other income for the
second quarter of the current year was $371,000, a 2% increase
from $365,000 for the same period last year.  For the six months
ended September 30, 1997, interest and other income also
increased 2% from the corresponding period of the prior year.

Provision for Income Taxes:  The Company's effective tax rate for
the six months ended September 30, 1997 was 34%, an increase
from 32% for the same period of last fiscal year.

Liquidity and Capital Resources:  On September 30, 1997, the
Company had $26,699,000 in cash, cash equivalents and short term
investments, compared with $23,633,000 on March 31, 1997.  This
increase is mostly due to positive cash flow from operating
activities consisting principally of net income and an increase
in liability accounts, and partially offset by an increase in
receivables.  Net cash used in investing activities as of second
quarter of fiscal year 1998 is $7,478,000 which consisted mainly
of purchases of short-term investments.  Net cash used in the
repurchase of stocks was $208,000 which was offset by proceeds
from stock option exercises of $205,000.

The Company anticipates that 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 year
1998.  The Company expects to spend approximately $6,827,000 for
capacity expansion during fiscal year 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 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.

In June 1997, the Financial Accounting Standards Board issued
Statement of  Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" (SFAS 130).  SFAS 130 establishes
standards 
<PAGE>

for reporting and display of comprehensive income and its 
components in a full set of general-purpose financial statements.  
Comprehensive income is defined as "the change in equity of a 
business enterprise during a period from transactions and other 
events and circumstances from nonowner sources.  It includes all 
changes in equity during a period except those resulting from 
investments by owners and distributions to owners."  SFAS 130 is 
effective for fiscal years beginning after December 15, 1997, and 
reclassification of financial statements for earlier periods 
provided for comparative purposes is required.  SFAS 130 is not 
expected to have a material impact on the Company's financial 
position, results of operations or cash flows.

In June 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related
Information" (SFAS 131).  SFAS 131 establishes standards for the
way that public business enterprises report information about
operating segments in annual financial statements and requires
that those enterprises report selected information about
operating segments in interim financial reports issued to
shareholders.  SFAS 131 generally supersedes Statement of
Financial Accounting Standards No. 14, "Financial Reporting for
Segments of a Business Enterprise."  Under SFAS 131, operating
segments are components of an enterprise about which separate
financial information is available that is evaluated regularly
by the chief operating decision maker in deciding how to
allocate resources and in assessing performance.  Generally,
financial information is required to be reported on the basis
that it is used internally.  SFAS 131 is effective for financial
statements for periods beginning after December 15, 1997, and
restatement of comparative information for earlier years is
required.  However, SFAS 131 is not required to be applied to
interim financial statements in the initial year of application.
SFAS 131 will not have a material impact on the Company's
financial position, results of operations or cash flows.
