ON Semiconductor: core business model

ON Semiconductor, which markets itself under the brand onsemi, focuses on power and sensing technologies used across automotive, industrial, cloud, and communications applications. The business targets segments that require high energy efficiency and reliability, such as electric vehicles, renewable energy systems and factory automation, as described in the company overview on its website, according to onsemi company information as of 03/20/2025. This positioning links the group closely to longer-term trends in electrification and digitalization.

The company’s strategy centers on providing highly differentiated products rather than competing primarily on commodity pricing. Management has emphasized a focus on intelligent power and sensing solutions, including silicon carbide (SiC) power devices that can help improve efficiency in electric drivetrains and fast-charging infrastructure, according to commentary surrounding its strategic update and earnings materials, as referenced by onsemi earnings presentation as of 04/29/2025. This approach aims to support margins and reduce exposure to more cyclical, lower-value segments.

ON Semiconductor operates a mix of internal manufacturing and external foundry relationships. In recent years the group has been reallocating capital toward 300mm fabrication and silicon carbide capacity to support higher-growth areas. This manufacturing footprint is an important part of the business model because automotive and industrial customers typically require long-term supply commitments and rigorous quality certifications, which can be more easily met with stable capacity and process control, according to the company’s capital spending commentary in past results noted by onsemi capital strategy materials as of 02/29/2024.

Customer relationships are another pillar of the business model. The company serves large global automakers, tier?1 automotive suppliers, and industrial equipment manufacturers, often under multi?year agreements. These contracts can provide a level of revenue visibility, although they also require ON Semiconductor to maintain competitive technology roadmaps and on?time delivery. This close integration into customer platforms means design wins can translate into multi?year production volumes, but it can also increase dependence on a relatively concentrated group of large clients.

Main revenue and product drivers for ON Semiconductor

ON Semiconductor’s revenue base is diversified across automotive, industrial, and other segments, with automotive being a key focus area. In its full?year 2024 report, the company highlighted automotive and industrial as its largest end markets, with automotive revenue supported by demand for electric vehicles, advanced driver assistance systems and powertrain electronics, according to onsemi results as of 02/05/2025. Content growth per vehicle, rather than unit growth alone, is an important revenue driver as automakers integrate more electronics into new models.

Silicon carbide has become one of the most closely watched product lines for ON Semiconductor. SiC devices can offer higher efficiency than traditional silicon in high?voltage applications, which can improve range and charging times in electric vehicles and reduce energy losses in renewable and industrial systems. The company has invested heavily in SiC substrate and device manufacturing, and it has signed multi?year agreements with several leading automakers and suppliers, according to contract announcements and commentary cited by Reuters as of 09/18/2024. These long?term deals are designed to underpin utilization of new capacity.

Beyond automotive, industrial applications range from automation and robotics to energy infrastructure and building management systems. These markets are driven by trends such as factory digitalization, smart grids, and energy efficiency standards. ON Semiconductor offers power modules, motor control ICs and sensing devices that support these applications. Industrial demand can be cyclical, but the company views the long?term trajectory as positive, with electrification and efficiency regulations supporting adoption, according to comments in its fourth?quarter 2024 materials, as noted by onsemi presentation as of 02/05/2025.

The cloud and communications segment includes power solutions for data centers, 5G infrastructure and networking equipment. While this area is smaller than automotive for ON Semiconductor, it ties into the broader AI and cloud computing trend. Data centers require efficient power distribution and conversion to handle rising compute loads and cooling demands. ON Semiconductor’s role is mainly on the power side rather than providing the AI processors themselves, but demand for efficient power components can rise as hyperscalers expand capacity, as indicated in sector commentary from Bloomberg as of 11/07/2024.

Another driver is the company’s push toward higher?margin, intelligent sensing solutions, including image sensors and other sensing technologies for automotive and industrial use. These products can support advanced driver assistance, industrial vision systems and security applications. While ON Semiconductor has streamlined its portfolio and exited some lower?margin businesses in recent years, it continues to invest in sensing products that complement its power solutions and provide system?level offerings for key customers, according to portfolio optimization commentary referenced by AP/Business Wire as of 06/12/2024.
