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. This execution guarantees massive future dominance.
ON Semiconductor possesses a complex, bureaucratic founding story, representing a strategic corporate unbundling executed by one of the most historic, foundational titans of the American electronics industry. The foundational DNA of the company traces entirely back to the legendary Motorola Corporation. During the 1950s and 60s Motorola was a dominant pioneer in early solid-state electronics, famously producing some of the world's very first commercially viable transistors for advanced radios and televisions. However, by the late 1990s Motorola was a bloated, complex conglomerate. It was heavily trying to dominate the explosive, lucrative mobile phone market (famously building the iconic StarTAC). The semiconductor division, which manufactured basic, commoditized analog chips, was seen as a distractive drag on the glamorous wireless business. In 1999, Motorola executed a strategic decision: they spun off the unglamorous Semiconductor Components Group into an independent company. Heavily orchestrated by private equity firm Texas Pacific Group (TPG), the new company was heavily branded as ON Semiconductor. While its initial corporate structure was debt-laden and burdened by inefficient legacy Motorola factories, it possessed foundational engineering expertise. By severing ties with the distracting consumer electronics business, ON Semiconductor was forced to forge its own gritty, specialized path, ultimately establishing the focused infrastructural architecture it heavily utilizes today.
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.
Since its establishment in 1999, ON Semiconductor Corporation expanded from an early-stage venture into a recognized leader in Power and sensing semiconductors, overcoming key market challenges.
Over its history, ON Semiconductor Corporation executed decisive strategic pivots toward scalable monetization and digital distribution, securing its current market leadership.
By continually modernizing operations and embracing workflow automation, ON Semiconductor Corporation maintains resilience through changing technological and economic cycles.
