Product Overview


Vishay Intertechnology manufactures several kinds of discrete semiconductors. These typically perform a single function, such as switching, amplifying, rectifying, or transmitting electrical signals.

Vishay Intertechnology also manufactures selected ICs, which combine the functions of multiple components on a single chip,as well as modules, which include multiple components in a single package.Vishay Intertechnology’s semiconductors portfolio includes MOSFETs (low-voltage, medium-voltage, and high-voltage), ICs (both powerand analog), a wide range of diodes and rectifiers, and many different types of optoelectronic products.

Vishay Intertechnology’s optoelectronics portfolio includes infrared receivers used in consumer electronics for remote controland in industrial applications for long-range sensing of objects; optocouplers and solid-state relays to optically isolate high-voltage sources from low-voltage control circuitry found in industrial applications like motor control loop feedback, control of valves, and solenoids, and to drive high-voltage IGBTs and MOSFETS; and infrared emitters for TV remote controls, automotive adaptive cruise control and heads-up-displays, smoke detectors, and a host of industrial applications. The optoelectronics product portfolio also includes reflective and transmissive optical sensors to determine the presence or proximity of objects and for encoding applications; phototransistors and PIN photodiodes to detect visible and infrared light; LEDs for a variety of automotive and industrial lighting applications; and infrared transceivers for wireless data transfer.Vishay’s growing portfolio of digital output sensors, including ambient light, RGB, UV, and gesture control sensors, has been enhanced by the integration of in-house IC design capabilities.
