Vishay Intertechnology Inc. designs, manufactures, and supplies discrete semiconductors and passive components. The company operates in five segments: MOSFETs, Diodes, Optoelectronic Components, Resistors & Inductors, and Capacitors. The MOSFETs segment offers low- and medium-voltage TrenchFET MOSFETs, high-voltage planar MOSFETs, high voltage Super Junction MOSFETs, power integrated circuits, and integrated function power devices. The Diodes segment provides rectifiers, small signal diodes, protection diodes, thyristors/silicon-controlled rectifiers, and power modules. The Optoelectronic Components segment offers infrared (IR) emitters and detectors, IR remote control receivers, optocouplers, solid-state relays, optical sensors, light-emitting diodes, seven-segment displays, and IR data transceiver modules. The Resistors & Inductors segment provides film, wirewound, power metal strip, variable, and non-linear resistors, as well as battery management shunts, chip fuses, networks/arrays, magnetics, and connectors. The Capacitors segment offers tantalum, ceramic, film, power, heavy-current, and aluminum capacitors. The company's semiconductor components are used for various functions, including power control, power conversion, power management, signal switching, signal routing, signal blocking, signal amplification, two-way data transfer, one-way remote control, and circuit isolation; and passive components are used to restrict current flow, suppress voltage increases, store and discharge energy, control alternating current and voltage, filter out unwanted electrical signals, and perform other functions. It serves industrial, computing, automotive, consumer, telecommunications, power supplies, military, aerospace, and medical markets. Vishay Intertechnology offers its products to the manufacturers primarily in the United States, Europe, and Asia. The company was founded in 1962 and is headquartered in Malvern, Pennsylvania.
