ON Semiconductor Corporation (stylized and doing business as onsemi) is an American semiconductor supplier company, based in Scottsdale, Arizona. Products include power and signal management, logic, discrete, and custom devices for automotive, communications, computing, consumer, industrial, LED lighting, medical, military/aerospace and power applications. onsemi runs a network of manufacturing facilities, sales offices and design centers in North America, Europe, and the Asia Pacific regions. Based on its 2016 revenues of $3.907 billion,[2] onsemi ranked among the worldwide top 20 semiconductor sales leaders,[3] and was ranked No. 483 on the 2022 Fortune 500 based on its 2021 sales.[4][5]
History
The company was founded in 1999. It was originally a spinoff of Motorola's Semiconductor Components Group headquartered in Phoenix, Arizona. It continues to manufacture Motorola's discrete, standard analog, and standard logic devices. On April 28, 2000, Onsemi launched its initial public offering (IPO).[6]
Steve Hanson was the first president and chief executive officer of the company until 2002. Keith Jackson from Fairchild Semiconductor replaced Hanson as the second leader for the next 20 years.
