Vishay Telefunken

Vishay Semiconductors includes the former Vishay Telefunken product lines, the former General Semiconductor product lines, the infrared component product lines acquired from Infineon Technologies, and selected product lines acquired from International Rectifier (excluding planar high-voltage MOSFETs).

The Vishay Semiconductors product portfolio includes rectifiers, fast-recovery diodes, high-power diodes and thyristors, small-signal diodes, Zener and suppressor diodes, RF transistors, optoelectronics, power modules (a combination of power diodes, thyristors, MOSFETs, and IGBTs), and automotive modules and assemblies.

Vishay is the world’s number one manufacturer of rectifiers, glass diodes, and infrared components.

Telefunken was founded in the 1920s by German companies Siemens and AEG. Its name is a combination of the prefix “tele” and the German word meaning “spark” or “transmission.” Telefunken’s original focus on high-frequency electrical transmissions for radio eventually led it to become an important supplier to the broadcasting and television industry.
