How onsemi Makes Money

onsemi makes money by selling semiconductors to automakers, tier-1 suppliers, industrial equipment makers and data center power-supply builders, largely through distributors and direct design wins. Revenue is reported in three groups: the Power Solutions Group (silicon and silicon carbide power devices and modules), the Analog and Mixed-Signal Group (power management, sensor interface and connectivity ICs) and the Intelligent Sensing Group (image sensors). The company runs its own fabs, including vertically integrated SiC production from crystal growth to modules after buying GT Advanced Technologies in 2021, so margins swing with factory utilization. Automotive design wins typically last for years, which gives visibility but also exposes onsemi to EV demand cycles.

Management is widening onsemi beyond EV traction inverters into AI data center power (aided by the 2025 Qorvo SiC JFET and Aura Vcore deals), industrial and energy infrastructure, and "physical AI" edge devices through the pending Synaptics acquisition. It is also exiting or selling under-used facilities and raising prices to lift factory utilization and margins.
