IXYS Corporation was a global supplier of power semiconductors, integrated circuits (ICs), and RF systems. Founded in 1983, the company specialized in developing and marketing high-performance power management and control solutions for a wide range of applications, including industrial, communications, consumer, and medical markets. IXYS was known for its broad product portfolio, including power MOSFETs, IGBTs, thyristors, rectifiers, microcontrollers (MCUs), and solid-state relays. In January 2018, IXYS Corporation was acquired by Littelfuse, Inc., a global manufacturer of technologies in circuit protection, power control, and sensing. The IXYS product portfolio is now part of Littelfuse's offerings.
Former global headquarters responsible for corporate management, research and development, engineering, marketing, sales, and administrative functions for IXYS Corporation prior to its acquisition.
The Milpitas facility likely housed administrative offices, engineering labs, and potentially some specialized testing or R&D facilities characteristic of a semiconductor company.
Historically, IXYS was recognized for an engineering-centric culture emphasizing innovation, technical expertise, and customer-focused solutions in the power semiconductor industry.
This location served as the central operational and strategic hub for IXYS Corporation, guiding its global business activities and product development until its acquisition by Littelfuse.
Prior to its acquisition by Littelfuse in 2018, IXYS Corporation maintained a significant global footprint. This included corporate headquarters and R&D facilities in North America, major operational centers (including R&D, manufacturing, and sales) in Europe (notably Germany and the UK), and various sales, support, and design offices across Asia. This global network enabled IXYS to serve a diverse customer base across industrial, communications, consumer, and medical markets worldwide with its power semiconductors and integrated circuits.
