Growth Through Innovation and Acquisition

Vishay was founded in 1962 to manufacture and market foil resistors, an invention of physicist Dr. Felix Zandman, Chairman of the Board and founder. The Company began operations with foil resistors and strain gages as its initial product offerings. In 1985, having grown from a start-up into the world's leading manufacturer of these original products, Vishay began an ongoing series of strategic acquisitions to become a broad-line manufacturer of electronic components that provides "one-stop shop" service to customers. Today, Vishay is one of the world's largest manufacturers of discrete semiconductors and passive electronic components.

Vishay's acquisitions include such top names as Siliconix, Telefunken, the infrared component business of Infineon, General Semiconductor, Dale, Draloric, Sprague, Vitramon, and BCcomponents (the former passive components business of Philips Electronics and Beyschlag). These names and the products associated with them are integrated into one global company: Vishay.

Vishay components are used in virtually all types of electronic devices and equipment, in the industrial, computer, automotive, consumer, telecommunications, military, aerospace, and medical markets. Vishay's global footprint includes manufacturing facilities in China and other Asian countries, Israel, Europe, and the Americas, and sales offices around the world. Vishay sales offices in Asia are responsible for the generation of over one-third of total Vishay revenues.

"One-Stop Shop" Service

With Vishay's "one-stop shop" service, customers can send their bills of materials (BOMs) to Vishay and ask the Company to cross-reference Vishay products in all categories. This enables customers to order multiple components from one sourceVishay. In addition, Vishay's product sample service for design engineers provides free product samples worldwide. For more information about Vishay samples, please visit us on the Web at www.vishay.com/how/samples or contact a local Vishay sales representative or office.

Vishay has a diverse product portfolio  from specialty to commodity components  from resistors, capacitors, inductors, transducers and strain gages (passives) to diodes, rectifiers, transistors, MOSFETs, power ICs, analog switches and multiplexers (actives) to infrared data communication devices (IRDCs), LEDs, and IR emitters, detectors, and receiver modules (optoelectronics). Vishay's ability to provide "one-stop shop" service to customers, innovations in technology, superior product quality, successful acquisition strategy, and focus on cost reduction has made the company a global industry leader.

Discrete Semiconductors

Vishay Siliconix is the number 1 manufacturer worldwide of low-voltage power MOSFETs (metal-oxide semiconductor field-effect transistors) used to manage, switch and convert power in computers, cell phones, and the communications infrastructure, and to control motion in computer disk drives and automotive systems.

Vishay Siliconix silicon technology and device-packaging milestones include the industry's first power MOSFETs built on a Trench silicon process (TrenchFET®s) and the industry's first power MOSFETs offered in small-outline, surface-mount packages (LITTLE FOOT®). This tradition of innovation continues with new technologies, such as WFET", designed to maximize power MOSFET performance in such applications as dc-to-dc conversion and load switching, and with new package options for better thermal performance (PowerPAK®) and smaller footprints (ChipFET®, MICRO FOOT®). Vishay Siliconix products also include power integrated circuits, as well as analog switches and multiplexers.

Power conversion for cell phones, notebook computers, and the fixed telecom infrastructure is the focus of Vishay Siliconix power IC developments, while new analog switching ICs are focused on lower-voltage, space-constrained applications.

Vishay Semiconductors is the number 1 manufacturer worldwide of infrared data communications devices (IRDCs), rectifiers, glass diodes, and IR receiver modules. The Vishay Semiconductors brand combines the products formerly branded Vishay Telefunken, and General Semiconductor, as well as the former infrared components business of Infineon Technologies.

Vishay's strength in advanced IR technologies such as high-radiant, double-hetero GaAlAs technology and fast, high sensitive photo PIN diodes provides the basis for Vishay's success in high-speed infrared transceivers for data communication and infrared receiver modules. In optocouplers, Vishay Semiconductors products comply with key safety standards such as VDE, UL, CSA, Fimko and BSI, and are used worldwide to make safer switchmode power supplies, AC/DC converters, and battery chargers.

The Vishay Semiconductors portfolio include Schottky, small-signal switching, RF-band switching, FM capacitance, RF PIN, suppressor, and Zener diodes, as well as bridge rectifiers, Schottky rectifiers, and fast- and ultra-fast- switching soft-recovery rectifiers and sinterglass Diodes. Small-signal transistors (RF and AF) and MOSMICs® complete the Vishay Semiconductors portfolio.

Passive Components

Vishay is the world's number 1 manufacturer of several categories of the passive components used in virtually all electronic systems. Power management, signal conditioning, motor control, data acquisition, and data transmission are just a few of the applications in which passive components from Vishay play a vital role.

Resistors

Vishay is the world's number 1 manufacturer of many types of resistors, including wirewound power resistors, foil resistors, thin film resistors, MELF resistors, leaded power film resistors, and leaded fusible resistors. This expansive product offering serves applications at all voltage levels and in all electronics market segments, from military and industrial to automotive and portable. Vishay innovations include low-value wirewound and Power Metal Strip® chip resistors and flip chip Bulk Metal® Foil resistors aimed at high-volume, high-precision analog applications.

In addition to its fixed resistors, Vishay offers variable resistors in several configurations, including potentiometers, trimmers, motion transducers, encoders, and dials. Non-linear NTC and PTC thermistors, and metal oxide varistors are also available.
