The History and Development of Vishay Semiconductor

Vishay Semiconductor's history dates back to 1962, when it was founded by Dr. Felix Zandman. Dr. Zandman, a distinguished scientist and entrepreneur, leveraged his profound understanding of resistor technology to establish Vishay's predecessor, Vishay Intertechnology. In its early days, the company focused on developing high-precision thin-film resistors, which quickly gained market recognition for their superior stability and reliability.

Over time, Vishay has continuously expanded its product line and technological capabilities through a series of strategic acquisitions. For example, in 1985, Vishay acquired Draloric Electronics GmbH in Germany, which significantly enhanced the company's competitiveness in discrete semiconductors such as diodes and transistors. Furthermore, Vishay has acquired several well-known electronic component manufacturers, including Siliconix, BE Semiconductor Industries, and BCcomponents, further solidifying its leading position in the industry.

Today, Vishay Semiconductor has grown into a diversified company with over 20,000 products, covering discrete semiconductors, passive components, integrated modules, stress sensors, and other related fields. Vishay plays a vital role in both traditional electronics manufacturing and emerging high-tech industries.
