Supertex Updates Second Fiscal Quarter Guidance, and

Schedules Earnings Release and Conference Call

Sunnyvale, CA (October 15, 2010) - Supertex, Inc. (NASDAQ GS: SUPX) today announced that it expects second fiscal quarter revenue to be in the range of $22,000,000 to $22,500,000 after accounting for its inventories at distributors and major customer hubs. This represents a decline of 12% from the Company’s previous sales guidance for the second fiscal quarter of an 8% to 10% sequential increase, which translated into expected revenue of $25,000,000 to $25,500,000.  The shortfall was primarily in LED driver sales, which in part resulted from our customers instructing us to temporarily suspend shipments late in September due to a slowdown in their LED TV sales. Medical ultrasound business remained strong. The Company believes the decline in LED driver sales for LCD TV backlighting is temporary and will recover as LED TV sales rebound for the coming holiday season.

The Company plans to announce financial results for its second fiscal quarter ended October 2, 2010, after the market close on Tuesday, October 26, 2010. It will host a conference call at 2:30 p.m. PDT (5:30 p.m. EDT) on October 26, 2010, following the earnings release.  Dr. Henry C. Pao, President and Chief Executive Officer, will present an overview of the second fiscal quarter results, discuss current business conditions, and then respond to questions.

The call is available live for any interested party by dialing 800-862-9098 (domestic) or 785-424-1051 (toll, international) before the scheduled start time and requesting to be connected to the Supertex earnings call.  A recorded replay will be available immediately after the conference call ends by calling 800-283-4783 (domestic) and 402-220-0859 (toll, international) until November 26, 2010.
