ON SEMICONDUCTOR CORP (ON)

onsemi (ON Semiconductor Corporation, incorporated in Delaware in 1992) offers intelligent power and intelligent sensing semiconductor solutions that drive electrification, energy efficiency, safety and automation. Its power technologies enable electric vehicle drivetrains, fast-charging systems, solar and industrial power, medical devices such as continuous glucose monitors, and energy-efficient AI data center power. Its sensing technologies support automotive safety and ADAS, factory and building automation, and robotics. Revenue comes primarily from selling semiconductor products to distributors and direct customers, and to a much lesser extent from product development agreements. In 2025 the company acquired Qorvo's SiC JFET technology business and Vcore power technology rights from Aura Semiconductor, and it carried out a manufacturing realignment program that included about 2,400 employee terminations.

The company has three reportable segments. Power Solutions Group (47% of 2025 revenue) provides silicon carbide, SiC JFET, discrete, MOSFET, power module, vertical GaN and gate driver products. Analog and Mixed-Signal Group (38%) provides analog, ASIC, logic and isolation, non-volatile memory, ultrasonic and inductive sensing products, including power management, connectivity and sensor-interface devices delivered through its Treo Platform. Intelligent Sensing Group (15%) provides CMOS image sensors, image signal processors, SWIR sensors, single photon detectors, indirect time-of-flight sensors and actuator drivers.

onsemi sells to direct customers and distributors for use in many end-products. By end-market, automotive accounted for 51% of 2025 revenue, industrial 28%, and other markets (AI data center, computing, consumer, networking and communications) 21%. Distributors, who resell to OEMs, contract manufacturers and other end-customers, represented about 54% of 2025 revenue, with one distributor at about 11%. Direct customers, mainly large multinational companies and selected regional OEMs, represented about 46%. Sales are made mainly under orders booked up to 52 weeks ahead. Standard warranties run two years, or one year for image sensors.

The company operates front-end wafer fabs in the United States, the Czech Republic, Japan, South Korea and Malaysia, and back-end assembly and test sites in Canada, China, Malaysia, the Philippines, Vietnam and the United States. It also makes SiC crystal boules in Hudson, New Hampshire, and silicon and SiC wafers in the Czech Republic and South Korea. Design operations are located across the United States, Europe, Asia and Israel, and distribution centers are in China, the Philippines and Singapore. Raw materials include silicon and SiC wafers, laminate substrates, gold, copper, lead frames, mold compound, ceramic packages, chemicals and gases. Competitors include Infineon, STMicroelectronics, Wolfspeed, ROHM and Nexperia in power; Texas Instruments, Analog Devices, Renesas, Monolithic Power Systems and NXP in analog; and Sony, Samsung and Omnivision in imaging.
