Company History
Founded 1999 in Scottsdale, Arizona, United States
onsemi traces its origins to 1999, with Motorola Semiconductor Products Sector spin-off tied to the founding story. The early choices around customers, products, and operating discipline still shape how the company competes today. The Fairchild acquisition and later silicon carbide pivot moved onsemi deeper into high-value power semiconductors.
Motorola Semiconductor Products Sector (SPS) was established in 1955 as the semiconductor division of Motorola Corporation, headquartered in Austin, Texas. The division was initially focused on discrete semiconductor devices such as transistors and diodes, but expanded into integrated circuits in the 1960s. In 1974, Motorola SPS released the 6800 microprocessor, which became widely used in automotive, industrial, and consumer electronics applications. Throughout the 1980s and 1990s, the division developed the PowerPC processor in collaboration with IBM and Apple, created the first integrated RF transceiver, and expanded manufacturing globally. By the late 1990s, SPS had become one of the world's largest semiconductor manufacturers but was increasingly seen as a non-core asset by Motorola's management, who wanted to focus on mobile phones and communications infrastructure. In 1999, Motorola spun off SPS into a separate publicly traded company called ON Semiconductor, which inherited the division's product portfolio, manufacturing assets, and customer relationships. The spin-off was one of the most successful semiconductor divestitures in history, creating a company that would grow from $1.2 billion in initial revenue to over $8 billion at its peak through a series of strategic acquisitions and organic growth initiatives.
ON Semiconductor was formed from Motorola Semiconductor Products Sector.
The Fairchild deal deepened onsemi power semiconductor scale and customer reach.
Hassane El-Khoury became President and CEO and led the strategic shift toward higher-value power and sensing markets.
onsemi reported $5.995 billion of revenue and $121.0 million of net income attributable to onsemi for FY2025.
ON Semiconductor acquired Fairchild Semiconductor for $2.4 billion in cash to create a top-10 non-memory semiconductor supplier with a comprehensive power management portfolio. Fairchild, founded in 1957, was a pioneer in power semiconductors that had invented the planar transistor and integrated circuit. The acquisition added approximately $1.5 billion in annual revenue and critical power semiconductor expertise.
ON Semiconductor acquired Qorvo's silicon carbide JFET technology business to address the AC-DC conversion stage in power supply units for AI data centers. The acquisition added JFET technology that enables high energy efficiency and power density in server power supplies, complementing ON Semiconductor's existing EliteSiC MOSFET portfolio.
ON Semiconductor acquired Aura Semiconductor's Vcore power technologies for up to $144 million to expand its power management portfolio for data center and AI applications. The acquisition added voltage regulator and power delivery technologies that complement the company's existing power management solutions.
