Supertex, Inc. is a publicly held mixed signal semiconductor manufacturer, focused in high performance analog and high voltage interface products for use in the medical, flat panel display, automotive, industrial electronics and telecommunications industries.

Our competitive and leadership position in these markets is focused on our efforts in designing new products with existing process technologies, while also developing new process technologies to be used in future products. Our direct and close customer involvement allows us to develop products and processes that have real market value and bring timely and cost effective solutions to meet the needs of our customers.

Since our inception in 1976, we have been a leader in developing advanced technologies that utilize high-performance Complementary Metal Oxide Semiconductors (CMOS) and Double-Diffused MOS (DMOS) processes. Twenty years ago we pioneered high voltage integrated circuitry with our proprietary HVCMOS® technology, a merging of the CMOS and DMOS process technologies onto one chip. Supertex HVCMOS chips have the “brains” and low power consumption of CMOS ICs and the high voltage output of DMOS FET transistors. These advanced HVCMOS ICs provide performance and cost benefits that give our customers a competitive edge in developing their products.
