History and Development of Vishay Semiconductor

Vishay Semiconductor's history can be traced back to 1962, when it was founded by Dr. Felix Zandman. Dr. Zandman was an outstanding scientist and entrepreneur who, with his deep understanding of resistor technology, founded Vishay Intertechnology, the predecessor of Vishay. In the early days, the company focused on developing high-precision thin-film resistors, which quickly gained market recognition for their excellent stability and reliability.

Over time, Vishay has continued to expand its product line and technological capabilities through a series of strategic mergers and acquisitions. For example, in 1985, Vishay acquired Draloric Electronics GmbH in Germany, which significantly improved the company's competitiveness in discrete semiconductors such as diodes and transistors. In addition, Vishay has also successively acquired a number of well-known electronic component manufacturers, including Siliconix, BE Semiconductor Industries and BCcomponents, further consolidating its leadership in the industry.

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