IXYS Corporation, a Littelfuse technology operating as a subsidiary following its 2018 acquisition by Littelfuse Inc., designs, develops and manufactures advanced power semiconductors, integrated circuits and RF systems for power management and control applications in industrial, transportation, telecommunications, medical, renewable energy and computing sectors; its core products encompass power MOSFETs rated from 60 to 4000 volts, insulated gate bipolar transistors (IGBTs) including XPT and reverse blocking variants, BIMOSFETs, fast recovery diodes (FREDs), thyristors, SCRs, GTOs, rectifier bridges (single-, half- and full-controlled, including 1- and 3-phase high voltage modules), diode/thyristor modules, solid-state relays, MOSFET/IGBT gate drivers, silicon carbide (SiC) power modules, PFC modules and power interface ICs such as HVICs, optically isolated drivers and ASICs. Founded in 1983 and historically headquartered in Milpitas, California, the company maintains global manufacturing and operations across North America, Europe (including facilities in Germany and the Netherlands) and Asia, serving over 2,500 customers with a portfolio addressing more than 90% of the power market spectrum from high-power discretes to refined MCUs and inverter components for wind/solar energy. The 2018 acquisition by Littelfuse for approximately $750 million in equity value expanded IXYS' power semiconductor capabilities in medium- and high-power applications, integrated its technologies into Littelfuse's broader portfolio for enhanced synergies in industrial OEM and power control markets, and positioned it as a cornerstone of Littelfuse's power semiconductor division with ongoing advancements in high-voltage, silicon carbide and energy-efficient solutions.
