The business traces its roots to 1999, when Motorola spun off its Semiconductor Components Group as ON Semiconductor. The company later expanded its scale and capabilities through organic development and acquisitions, including the 2016 acquisition of Fairchild Semiconductor. In 2021, ON Semiconductor rebranded and began operating under the onsemi name, while ON Semiconductor Corporation remains its legal registrant name.
Headquartered in Scottsdale, Arizona, onsemi has positioned its portfolio to address long-term industry trends such as vehicle electrification, energy efficiency, and the expanding role of sensors in automation and safety systems. Hassane El-Khoury has served as president and chief executive officer since 2020.
