IXYS Integrated Circuits Division, now a part of Littelfuse, is a renowned manufacturer of semiconductor devices and optically isolated electronic components. The division specializes in power semiconductors, radio-frequency (RF) power semiconductors, and digital and analog integrated circuits (ICs).

IXYS Corporation was founded in 1983 by Dr. Nathan Zommer in Silicon Valley, Santa Clara, California. Initially, it was a fabless power semiconductor device company. Over the years, IXYS expanded its capabilities and product portfolio through several acquisitions, including 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, IXYS Corporation was acquired by Littelfuse Inc. for $750 million in cash and stocks, and the acquisition was completed in January 2018.

• Power Semiconductors: IXYS focuses on medium- to high-voltage power semiconductors, including MOSFETs, IGBTs, and other devices used in industrial, communications, consumer, and medical device markets.
• RF Power Semiconductors: The division provides RF power semiconductors for amplification and reception applications.
• Integrated Circuits: IXYS designs and manufactures integrated circuits used in various applications such as Solid State Relays and Line Card Access Switches.

• High Voltage Wafer Fabrication: Expertise in high voltage wafer fabrication and isolation barrier/multi-chip packaging.
• Mixed Signal IC Design: Specialization in mixed signal IC design, enabling greater functionality, smaller footprint, and lower cost devices.
• Complementary Technology Expertise: The combination with Littelfuse brings together a broad power semiconductor portfolio and complementary technology expertise.

IXYS, now part of Littelfuse, holds a significant position in the global power semiconductor market. The acquisition by Littelfuse has enhanced its market presence by combining the companies’ complementary offerings and customer base, creating significant revenue synergy opportunities.

• MOSFETs: High-voltage MOSFETs, such as a 2000V N-Channel power MOSFET.
• IGBTs: High-power IGBTs used in applications like the KTX-II high-speed train.
• RF Power Semiconductors: Devices for amplification and reception.
• Laser Diode Drivers: Drivers for laser diodes.
• Direct Copper Bond (DCB): Technology used in various semiconductor applications.

The complete product catalog of IXYS is now integrated into Littelfuse's product offerings and can be found on the Littelfuse website. This includes a wide range of power semiconductors, integrated circuits, and other electronic components.

IXYS has provided products for several notable clients, including General Motors for the EV1 electric vehicle and the KTX-II high-speed train.
