ON Semiconductor

ON Semiconductor Corporation, doing business as onsemi, is a leading American semiconductor supplier company headquartered in Scottsdale, Arizona. Founded in 1999 as a spin-off from Motorola's Semiconductor Components Group, onsemi has evolved into a global powerhouse in intelligent power and sensing technologies. With over 80,000 different parts in its portfolio, including advanced MOSFETs, image sensors, and silicon carbide technology under the EliteSiC brand, the company serves tens of thousands of customers across multiple markets worldwide.

As of December 2024, onsemi employs approximately 26,000 people globally and generated $7.082 billion in revenue for 2024. The company has strategically positioned itself as a key supplier to the automotive and industrial sectors, focusing on technologies that enable energy efficiency and sustainability. The 2021 rebranding from ON Semiconductor to onsemi marked a strategic pivot toward higher-growth markets, particularly automotive electrification, industrial automation, and cloud power infrastructure.

The company operates as the second-largest power chipmaker in the world and holds the position of the largest supplier of image sensors to the automotive market. Onsemi's product portfolio spans power semiconductors, sensors, and connectivity solutions that address critical applications in electric vehicles, renewable energy systems, industrial automation, and 5G infrastructure. The company's vertically integrated manufacturing capabilities, combined with strategic partnerships with industry leaders like NVIDIA for AI data center solutions, position it at the forefront of the semiconductor industry's transition to intelligent power and sensing technologies.

Onsemi's business model emphasizes long-term customer partnerships, particularly in the automotive sector where design wins can span multiple vehicle generations. The company has made significant investments in silicon carbide (SiC) technology, completing the expansion of its SiC wafer factory in Bucheon, South Korea in 2023, with plans to transition to 8-inch production after completing technical verification in 2025. In late 2024 and early 2025, onsemi continued its aggressive expansion strategy by announcing the acquisition of Qorvo's Silicon Carbide JFET Business in December 2024 and completing the acquisition of Vcore Power Technology from Aura Semiconductor to strengthen its position in AI data center solutions.

The company's strategic focus on automotive and industrial end markets, particularly electric vehicle power systems and advanced driver assistance systems (ADAS), has positioned it well to capitalize on global megatrends including vehicle electrification, industrial automation, and sustainable energy infrastructure. Onsemi's commitment to innovation is reflected in breakthrough technologies like its vertical gallium nitride (vGaN) power semiconductors, which deliver record efficiency, power density, and ruggedness for AI and electrification applications. With a strong foundation built from its Motorola heritage and continuous evolution through strategic acquisitions and organic growth, onsemi stands as a critical enabler of the intelligent power revolution shaping the future of energy and mobility.
