ON Semiconductor (ON)

Onsemi is best known for power semiconductors, including devices that help control voltage, current, and energy efficiency in electronic systems. These components are increasingly important as vehicles, factories, data infrastructure, and energy systems become more electrified. The company has also built a leading position in automotive image sensors, which are used in driver-assistance systems, cameras, and other vehicle safety and automation applications.

The company’s strategy centers on higher-growth markets such as electric vehicles, advanced driver-assistance systems, industrial automation, renewable energy, and power infrastructure. In electric vehicles, its technologies can support traction inverters, charging systems, battery management, and other high-power applications. In industrial markets, its chips are used in motor control, robotics, machine vision, and energy management equipment.

Onsemi historically operated with a high degree of vertical integration, but it now uses a more flexible manufacturing approach that combines internal production with external capacity where appropriate. This hybrid model is intended to improve efficiency and support changing demand across its end markets.

What distinguishes onsemi is its combination of power management expertise and sensing capabilities. That mix aligns the company with long-term trends toward electrification, automation, and intelligent systems, while still leaving it exposed to semiconductor industry cycles and customer demand in automotive and industrial markets.
