In depth analysis of Vishay brand
Brand background and historical evolution
Vishay was founded by Dr. Felix Zandman in Pennsylvania, USA in 1962. Initially, its core products were foil resistors and foil strain gauges. Since 1985, the company has gradually expanded into a leading global manufacturer of discrete semiconductors (diodes, MOSFETs, optoelectronic components) and passive components (resistors, capacitors, inductors) through strategic acquisitions of top manufacturers such as Siliconix, Telefunken, Infineon's infrared component business, and General Semiconductor. After acquiring a portion of the international rectifier product line in 2007, Weishi further consolidated its market position in the field of electronic components.
