- ON Semiconductor Corporation (onsemi; Nasdaq: ON), founded in 1999 as a spin-off from Motorola's Semiconductor Components Group and headquartered in Scottsdale, Arizona, designs, manufactures and markets a broad portfolio of energy-efficient power management, sensing, signal management, logic, discrete and custom semiconductor devices; core offerings span intelligent power solutions including AC/DC and DC/DC controllers, regulators, gate drivers, MOSFETs, IGBTs, silicon carbide (SiC) and gallium nitride (GaN) technologies; intelligent sensing solutions such as image sensors, environmental sensors and CMOS image sensors; signal conditioning and control products encompassing amplifiers, comparators, data converters, microcontrollers and digital potentiometers; connectivity technologies including Bluetooth Low Energy and interfaces; motor control systems with brushed, brushless and stepper drivers; discrete components like bipolar transistors, diodes, rectifiers and thyristors; and custom devices featuring ASICs, ASSPs, SoCs, SiPs and foundry services. The company serves automotive, industrial, cloud power, communications, computing, consumer electronics, medical and IoT markets, generating approximately 60% of 2024 revenue from automotive and 24% from industrial end-markets, with operations encompassing 19 manufacturing sites across 9 countries, 43 design centers in 19 countries and 8 solution engineering centers in 5 countries. onsemi rebranded from ON Semiconductor in 2021 to reflect its technology leadership; it completed the acquisition of Fairchild Semiconductor in 2016, enhancing its power and analog portfolio; recently expanded its world-largest SiC fabrication facility in Bucheon, South Korea, to over one million 200mm wafers annually, supporting EV and energy infrastructure demand; acquired Qorvo's SiC JFET technology business for $115 million in early 2025 to bolster its EliteSiC portfolio for AI data centers, EVs and industrial applications; signed a non-binding MOU with Innoscience in late 2025 to accelerate low- and medium-voltage GaN power device production, targeting a $2.9 billion market by 2030; licensed Weebit Nano's ReRAM technology for its Treo platform; and received European Commission approval for €450 million Czech state aid to expand semiconductor manufacturing capacity.
