IXYS Corporation, now a part of Littelfuse Inc., was a pioneering company in the power semiconductor market. Founded in 1983 by Dr. Nathan Zommer in Silicon Valley, California, IXYS specialized in power semiconductors, radio-frequency (RF) power semiconductors, and digital and analog integrated circuits (ICs).

IXYS was established in 1983 as a fabless power semiconductor device company. The company made significant contributions, including providing power MOSFETs for the General Motors EV1 in 1989 and high-power IGBTs for the KTX-II high-speed train. Over the years, IXYS expanded through acquisitions, such as the British semiconductor manufacturer Westcode in 2001, and Zilog in 2009. In 2013, IXYS acquired Samsung Electronics' 4- and 8-bit microcontroller business. In August 2017, Littelfuse Inc. acquired IXYS Corporation for $750 million in cash and stocks, and the acquisition was completed in January 2018, leading to IXYS being delisted from NASDAQ.

IXYS focused on several key business segments:

• Power Semiconductors: Including medium- to high-voltage power semiconductors used in industrial, communications, consumer, and medical device markets.
• RF Power Semiconductors: Designed for high-voltage applications and used in amplification or reception.
• Integrated Circuits: Used in solid-state relays, line card access switches, and other applications.
• Laser Diode Drivers and Direct Copper Bond (DCB) Technology: Supporting various high-power applications.

• Advanced Semiconductor Technology: IXYS was known for its innovative power semiconductor devices, including high-voltage MOSFETs and IGBTs.
• Comprehensive Product Portfolio: The company offered a broad range of products, from power MOSFETs to integrated circuits and RF power semiconductors.
• Engineering and Manufacturing Expertise: IXYS had strong in-house engineering and manufacturing capabilities, enabling the development of high-quality semiconductor products.

Before its acquisition by Littelfuse, IXYS was a global pioneer in the power semiconductor market. The company's products were widely used in various industries, including industrial, communications, consumer electronics, and medical devices. The acquisition by Littelfuse further strengthened its position in the power control and industrial OEM markets.

• Power MOSFETs: Including high-voltage N-Channel power MOSFETs.
• IGBTs: Used in high-speed trains and other high-power applications.
• RF Power Semiconductors: For amplification and reception in high-voltage applications.
• Integrated Circuits: For solid-state relays and line card access switches.
• Laser Diode Drivers and DCB Technology: Supporting various high-power applications.

Since the acquisition by Littelfuse, the complete product catalog of IXYS is now integrated into Littelfuse's product offerings and can be found on the Littelfuse website.

IXYS served a diverse range of clients across various industries, including automotive (e.g., General Motors), industrial (e.g., high-speed trains), communications, and medical devices. However, specific client names are not detailed in the available sources.

• Littelfuse Inc.: The parent company that acquired IXYS in 2018.
• Zilog: A wholly owned subsidiary of IXYS, now part of Littelfuse.
• Westcode: A British semiconductor manufacturer acquired by IXYS in 2001.
