**IXYS Corporation** is an American company based in [Milpitas, California](/source/Milpitas%2C_California). IXYS focuses on power [semiconductors](/source/Semiconductor), [radio-frequency](/source/Radio-frequency) (RF) power semiconductors, and digital and analog [integrated circuits](/source/Integrated_circuit) (ICs).[2]

## History

Dr. Nathan Zommer founded IXYS Corporation in 1983 in Silicon Valley, Santa Clara, California. IXYS was originally a [fabless](/source/Fabless) [power semiconductor device](/source/Power_semiconductor_device) company. In 1989, IXYS provided [power MOSFETs](/source/Power_MOSFET) for the [General Motors EV1](/source/General_Motors_EV1).[3]

IXYS provided high-power [IGBTs](/source/IGBT) for the [KTX-II](/source/KTX-II) high-speed train.[4]

In 2001, the company acquired the British semiconductor manufacturer Westcode.[5]

In December 2009, IXYS Corporation announced that it will buy [Zilog](/source/Zilog), which is now the company's wholly owned subsidiary.[6][7]

In July 2013, IXYS Corporation finished acquiring [Samsung Electronics](/source/Samsung_Electronics)' 4- and 8-bit microcontroller business, and the 4- and 8-bit microcontrollers acquired from Samsung will be offered by Zilog, Inc.[8]

In August 2017, IXYS Corporation was acquired by [Littelfuse Inc](/source/Littelfuse_Inc) in exchange for $750 million in cash and stocks.[9][10]

In January 2018, Littelfuse finished acquiring IXYS Corporation and IXYS was delisted from NASDAQ.[11]

## Products

Litelink CPC5621A, a phone line interface IC ([DAA](/source/Data_access_arrangement))

IXYS products included MOSFETs like a 2000V N-Channel power MOSFET, designed to be used in high voltage applications as well as integrated circuits used in Solid State Relays and Line Card Access Switches.[12][13][14] The **RF Power Semiconductors** convert high rates electricity for amplification or reception. In addition, IXYS provides laser diode drivers, direct copper bond (DCB).[15]
