What onsemi makes

onsemi (ON Semiconductor Corporation) designs and manufactures power and sensing semiconductors for the automotive and industrial markets, and it runs its business in two reportable segments: the Power Solutions Group and the Analog and Mixed-Signal group, which houses its Intelligent Sensing products. The company describes its focus as intelligent power and intelligent sensing, the silicon that manages electricity and captures images inside electric vehicles, factory automation, energy infrastructure, and AI data centers.

On the power side, the flagship line is EliteSiC, onsemi's silicon carbide MOSFETs and power modules used in EV traction inverters, onboard chargers, and DC-fast-charging systems. That portfolio sits alongside IGBTs, power modules, power management ICs, and a broad catalog of discrete and standard products. In 2024 the company introduced Treo, an analog and mixed-signal platform built on 65nm BCD process technology that spans a 1 to 90 volt range and operates up to 175 degrees Celsius. On the sensing side, the Hyperlux family of automotive image sensors supports advanced driver-assistance and in-cabin vision. onsemi supplies these parts to Tier 1 systems makers and directly to OEMs, sitting one or two levels up the supplier tier structure from the vehicle assembler.

Financial performance

onsemi reported revenue of $5,995.4 million for fiscal 2025, down 15 percent from $7,082.3 million in 2024, which in turn was down 14.2 percent from 2023. The decline tracks a broad semiconductor down-cycle, with softer demand in automotive and industrial end markets and lower factory utilization. GAAP gross margin was 33.1 percent in 2025, down from 45.4 percent in 2024.

GAAP operating income fell to $84.2 million and net income to $121.0 million in 2025, well below the $1,767.7 million operating income and $1,572.8 million net income of 2024. Most of that drop came from restructuring, asset impairment, and other charges tied to the 2025 Manufacturing Realignment Program rather than from the core operations weakening by the same magnitude. Cash generation held up: the company produced roughly $1.8 billion in cash from operations and $1.4 billion in free cash flow in 2025, a record free-cash-flow margin of about 24 percent. As of December 31, 2025, onsemi carried about $13.0 billion in total assets and $7.93 billion in total equity against roughly $3.0 billion of total debt principal, a low-leverage balance sheet for a company of its size.

Ownership and history

onsemi was formed in 1999 as a spin-off of Motorola's Semiconductor Components Group and listed on Nasdaq in 2000, where it trades under the ticker ON. The operating subsidiary is Semiconductor Components Industries, LLC. Over two decades the company grew through acquisitions, most notably Fairchild Semiconductor in 2016, which remains visible in its manufacturing footprint. Its headquarters moved in 2023 to a LEED Gold building at 5701 North Pima Road in Scottsdale, Arizona, on the Salt River Pima-Maricopa Indian Community. The company reports roughly 26,000 employees across more than 20 countries, with wafer fabrication in the United States and assembly and test operations concentrated in Southeast Asia. Leadership is led by Hassane El-Khoury, Executive Director, President and CEO, with Thad Trent as Executive Vice President and CFO, Achyut Shah leading the Power Solutions Group, and Sudhir Gopalswamy leading the Intelligent Sensing and Analog and Mixed-Signal group.

Certifications and quality

onsemi states that its manufacturing sites hold IATF 16949:2016, the automotive quality-management standard, along with ISO 9001:2015. Multi-site automotive certification is the sector norm for a supplier shipping into vehicle programs, and it is reported here as the company's own claim. Automotive-grade parts of this kind move through structured qualification, including PPAP submissions before a part reaches a production line.

Known customers

onsemi does not publish a full customer roster, which is normal for a semiconductor supplier bound by program confidentiality. Two automotive relationships are on the public record through the company's own announcements:

Beyond these, onsemi ships into a wide base of automotive Tier 1 and OEM programs and, more recently, into AI data-center power supplies, the stated rationale for its January 2025 acquisition of silicon carbide JFET technology from Qorvo.

Sourcing evidence

The US customs record for onsemi is unusual because the company is a manufacturer and exporter, not a large importer of finished goods. The most active US import entity on record is its On Semiconductor Reclaim Center in Phoenix, Arizona, with 681 sea shipments between January 2015 and May 2025. Those bills of lading are almost entirely intra-company: the top shippers are onsemi's own assembly and test sites, including On Semiconductor Vietnam, On Semiconductor Philippines, SSMP Philippines, On Semiconductor Binh Duong in Vietnam, Fairchild Semiconductor in the Philippines, and On Semiconductor Malaysia.

Six shown of the recorded shippers. By product, the flows split between semiconductor devices and integrated circuits moving from the fabs and aluminum, copper, and precious-metal waste and scrap moving into the Phoenix reclamation center, the materials-recovery side of a chip operation. Read correctly, this data maps onsemi's own Southeast Asian manufacturing footprint rather than a third-party supplier graph. It tells a buyer where onsemi builds, not who supplies onsemi.

Coverage caveats: these are US ocean-freight records only. Air freight, which carries most high-value semiconductor product, does not appear; some records name freight intermediaries rather than the manufacturing site; and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence.
