ON Semiconductor Corporation, publicly branded and doing business as onsemi, is a leading American multinational semiconductor supplier specializing in the design, manufacture, and sale of intelligent power and sensing solutions. Headquartered in Scottsdale, Arizona, the company operates a sprawling global infrastructure that includes 19 manufacturing sites across 9 countries, 43 design centers in 19 countries, and 8 solution engineering centers in 5 countries. As of late 2025, onsemi employs approximately 24,000 people worldwide. The company was originally established on July 4, 1999, as a spin-off of Motorola’s Semiconductor Components Group through a $1.6 billion leveraged buyout. Initially operating under the name ON Semiconductor, it focused on manufacturing and marketing high-volume standard products, including discrete semiconductors, standard analog, and standard logic devices. Over the years, the company transitioned from a broad supplier of lower-return commodity components to a highly specialized leader in emerging technology sectors. This strategic shift culminated in a major rebranding to onsemi in August 2021, signaling its refined focus on advanced automotive and industrial technologies. Onsemi operates primarily through three business segments: the Power Solutions Group (PSG), the Analog and Mixed-Signal Group (AMG), and the Intelligent Sensing Group (ISG). The PSG segment supplies discrete, module, and integrated semiconductor products essential for power conversion, signal conditioning, and circuit protection. The AMG segment focuses on the development of analog, mixed-signal, power management integrated circuits (ICs), and voltage regulation devices. The ISG segment designs complementary metal-oxide-semiconductor (CMOS) image sensors, image signal processors, and specialized sensors for automotive safety and advanced driver-assistance systems (ADAS). The company's modern growth model relies heavily on secular electrification trends, particularly in electric vehicles (EVs), factory automation, renewable energy infrastructure, and AI data centers. It has expanded significantly through a series of key strategic acquisitions, including Cherry Semiconductor (2000), AMI Semiconductor (2008), SANYO Semiconductor (2011), Aptina Imaging (2014), and a transformative deal to acquire Fairchild Semiconductor in 2016. To secure its leadership in wide-bandgap materials, onsemi acquired GT Advanced Technologies in 2021, facilitating complete vertical integration of its silicon carbide (SiC) supply chain from raw boules to completed modules. It also acquired a major 300-millimeter fab in East Fishkill, New York, from GlobalFoundries in 2022 to boost its internal manufacturing capacity. Financially, onsemi is a publicly traded company on the Nasdaq under the ticker symbol ON, with a market capitalization of approximately $47.3 billion. Led by President and CEO Hassane El-Khoury, who assumed leadership in December 2020, onsemi pursues a "fab-right" operational strategy that optimizes internal capacity while maximizing margins. Committed to sustainability, the company is a signatory to the United Nations Global Compact and has pledged to achieve net-zero greenhouse gas emissions by 2040.
