	     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1
------
In the opinion of management, the unaudited financial statements
for the nine months ended December 31, 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 third quarter ended December 31,
1997 increased 28% to $13,857,000 from $10,850,000 of the same
quarter last year.  Nine months net sales of $39,782,000
increased 10% from the same period last year of $36,230,000. 
Continued strength in our customers' markets contributed to this
increase in sales.  During the nine months ended December 31,
1997, approximately 53% of Supertex's shipments were to
international customers.

Gross Margin: Gross margin for the third quarter and nine months
ended December 31, 1997 were both 46% compared with 43% for the
same quarter and 47% for the nine months period of the prior
year.  The slight decrease in gross margin for the nine month
period is a result of the change in product mix toward less
mature products which caused the company to incur higher
engineering support costs.

Research and Development: As percentage of net sales, third
quarter R&D decreased slightly to 11% from 12% of the same
quarter last year.  For the nine month period, such expenses
remained constant at 11% when compared to the same period of
last year.  However, dollar expenditures increased 10% to
$1,464,000 for the three months ($4,265,000 for nine months)
ended December 31, 1997 from $1,326,000 for three months
($3,860,000 for nine months) of last year primarily due to
increase in payroll despite reduction in outside services. 

Selling, General and Administrative: Selling, general and
administrative expenses for the third quarter and nine months
ended December 31, 1997 were both 13% of net sales, compared
with 14% for the same quarter and 13% for the nine months period
of the prior year.  Fixed costs remained fairly constant from
year to year in this category, with sales commission increasing
in line with increased sales.

Interest and Other Income: Interest and other income for the
third quarter of the current year was $432,000, a 17% increase
from $369,000 for the same period last year.  For the nine
months ended December 31, 1997, interest and other income
increased 7% from the corresponding period of the prior year. 
The increases in interest income for the quarter and nine month
period are associated with the Company's higher cash balances. 
See Liquidity and Capital Resources below.

Provision for Income Taxes: The Company's effective tax rate for
the nine months ended December 31, 1997 was 34%, an increase
from 32% for the same period of last year.

Liquidity and Capital Resources: On December 31, 1997, the
Company had $29,766,000 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 and inventories.  Net cash used in investing
activities as of third quarter of fiscal year 1998 is $5,792,000
which consisted mainly of purchases of short-term investments
and capital equipment purchases.  Net cash used in the
repurchase of common stock was $419,000 which was partially
offset by proceeds from stock option exercises amounting to
$333,000.

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 was able to reduce the original budget for
capacity expansion during fiscal year 1998 by better planning
and unexpected availability of good surplus capital equipment at
less than the original budgeted amount. 

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 
<PAGE>

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.
