Vishay Intertechnology, Inc. is an American manufacturer of discrete semiconductors and passive electronic components founded by Polish-born businessman Felix Zandman.

Vishay has manufacturing plants in Israel, Asia, Europe, and the Americas where it produces rectifiers, diodes, MOSFETs, optoelectronics, selected integrated circuits, resistors, capacitors, and inductors.

Since 1985, Vishay has pursued a business strategy that principally consists of the following elements: expanding within the electronic components industry, primarily through the acquisition of other manufacturers of electronic components; reducing expenses; transferring manufacturing operations to countries with lower labor costs and government-sponsored incentives; maintaining significant production facilities in regions where Vishay markets the bulk of its products; continually rolling out new products; and strengthening relationships with customers and strategic partners.
