International Rectifier was an American power management technology company manufacturing analog and mixed-signal ICs, advanced circuit devices, integrated power systems, and high-performance integrated components for computing. On 13 January 2015, the company became a part of Infineon Technologies.^[1]

IR's products, as a part of Infineon Technologies' overall semiconductor portfolio, continue to be used in many applications including lighting, automobile, satellite, aircraft, and defense systems; as well as key components in power supply systems in electronics-based products that include especially microcomputers, servers, and networking and telecommunications equipment.

History

• 1954: commercialization of germanium rectifiers
• 1959: creation of the first silicon-based rectifier
• 1974: first power and Darlington transistors which used glass passivation
• 1979: first hexagonal MOSFET
• 1983: first intelligent power ICs
• 1983: lost a patent infringement lawsuit over the rights to doxycycline to Pfizer, Inc., resulting in a judgment of $55 million to Pfizer. To avoid bankruptcy, the International Rectifier gave Pfizer its animal health and feed additive businesses.^[2][3]
• 2000: developed FlipFET^TM wafer packaging
• 2002: developed DirectFET^R, a MOSFET packaging technology developed to address thermal limitations found in advanced computing, consumer and communications applications
• 2003: developed iMOTION^TM Integrated Design Platform for motor control applications
• 2006: introduced SmartRectifier^TM IC for AC/DC applications
• 2007: launched SupIRBuck^R integrated voltage regulators
• 2008: introduced revolutionary GaN-based power device platform
• 2011: introduced PowIRstage^R devices and CHiL^R digital controllers
• 2012: launched micro integrated power modules for motor control applications and COOLiRIGBTs^R for automotive.
• 2014: bought by Infineon Technologies for $3 billion.^[4]
• 2015: officially becomes a part of Infineon Technologies
