About Vishay Intertechnology


Vishay Intertechnology was founded in 1962 by Dr. Felix Zandman, with a loan from his cousin Alfred P. Slaner. The Company was named after Dr. Zandman’s ancestral village in Lithuania, in memory of family members who perished in the Holocaust. The Company’s initial product portfolio consisted of foil resistors and foil resistance strain gages. In 1985, having grown from a start-up into the world’s leading manufacturer of these products, the Company began a series of strategic acquisitions to become a broad-line manufacturer of electronic components. Today, Vishay Intertechnology is one of the world’s largest manufacturers of discrete semiconductors and passive electronic components.


Vishay is very well positioned to provide components for macroeconomic growth drivers such as connectivity, mobility, and sustainability. Through its R&D, engineering, quality programs, and sales initiatives, it generates a steady stream of innovative components to enable designers to create new generations of end products.
In connectivity-related products such as tablets, smartphones, and wearables, Vishay components support power management, wireless connectivity, display interface, and touch screen controls; provide protection from the electrostatic discharge (ESD) that can cause component and system failure; and perform other functions. Vishay components are also found in wireless charging devices, mobile payment systems and other near-field communications systems, servers, network devices, base stations, solid-state drives, telematics systems, and other products and systems in our increasingly interconnected world. Vishay’s latest technologies and components support the development of 5G network technologies and play important roles in Internet of Things (IoT) devices.
In the area of mobility, Vishay components support a wide range of functions in electric power steering, including electromagnetic interference (EMI) filtering, quiescent current switch-off, three-phase motor switching, current sensing, and voltage division. Vishay components also are used in transmission control units, power management, boardnet stabilization and voltage conversion, exhaust systems, start-stop systems, climate controls, braking and safety, lighting, infotainment, proximity and gesture recognition, and more. In hybrid and fully electric vehicles, Vishay components are used in main inverters, high-voltage bus systems, energy recuperation, and charging systems. Advanced driver assistance systems are supported by optical sensors. They also support Car-to-X communications, high frequency transceivers, and radar devices. Power capacitors, inductors, and high power resistors are used in high speed trains, buses, aircraft, and ships, as well as intralogistics systems, in modern infrastructure.
In the area of sustainability, Vishay components support the new generation of factory automation – Industry 4.0 – to enable robots with position sensors and encoders, enable haptic response, increase the efficiency of motor drives, and enable automated transport systems in warehouses. Vishay components are also used in alternative energy products and systems, such as the main inverters, power filters, and pitch and system controls in wind turbines. Components in wind turbine systems include high power semiconductor modules, high voltage MOSFETs, power ICs, diodes and rectifiers, optical isolators, shunt resistors, crowbar resistors, inductors, and power capacitors. Vishay components are used in solar panels and inverters, and for on-panel power conversion. They are used in smart meters and smart grids, power transmission and distribution systems, power grid quality stabilization, oil and gas exploration equipment, energy harvesting, and more.

Vishay Intertechnology Products


Vishay 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’s semiconductors portfolio includes MOSFETs (low voltage, medium voltage, and high voltage), ICs (both power and analog), a wide range of diodes and rectifiers, and many different types of optoelectronic products.
Vishay’s optoelectronics portfolio includes infrared receivers used in consumer electronics for remote control and in industrial applications for light barriers; optocouplers and solid-state relays to galvanically isolate control circuitry found in industrial applications like motor control loop feedback, control of valves, and solenoids, and to drive IGBTs and MOSFETs; and infrared emitters for TV remote controls, CCTV cameras, smoke detectors, and other 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.
Diodes and Rectifiers
Diodes are used in a wide range of electronic systems to route, switch, and block radio frequency (RF) signals. Vishay Intertechnology diodes include all types of rectifiers; small signal switching, Zener and PIN diodes; and products for transient voltage suppression (TVS), electrostatic discharge (ESD) protection, and electromagnetic interference (EMI) filtering. Rectifiers convert alternating current (AC) into direct current (DC), a unidirectional current required for operation of many electronic systems. Vishay Intertechnology rectifiers, including patented TMBS® and FRED Pt® devices in low profile eSMP® packages, save space, reduce power losses, and improve efficiency in automotive, industrial, telecommunications, computing, and other applications. TVS product lines include PAR® devices that offer 185 °C junction temperature performance and are targeted at automotive applications. The Vishay diodes and rectifiers portfolio also includes power modules, which integrate multiple electronic components.
Vishay Siliconix MOSFETs and ICs enable more efficient use of power and space, enabling improved designs wherever they are used — in smartphones, cloud computing, automobiles, medical equipment, consumer electronics, and many other applications. The Vishay Siliconix portfolio includes discrete power MOSFETs, power conversion ICs, analog switches, and power management ICs across a large range of voltages and in many different package types. Together, they provide customers with the opportunity to optimize their designs with the right mix of integration, performance, and smaller form factors.
In the world of power semiconductors, advances in silicon and packaging technology are highly complementary, and Vishay Siliconix has been synonymous for decades with excellence in both. Since introducing the first TrenchFET® power MOSFET more than 20 years ago, Vishay Siliconix has produced generation after generation of best-in-class performance levels for discrete devices, as well as for power ICs that integrate multiple power management and control functions. Packaging innovations used in all Vishay Siliconix product lines have enabled ever higher levels of integration, power density, size optimization, and thermal capabilities that play a key role in the creation of more competitive, powerful, and efficient designs.
