ON Semiconductor Corporation, together with its wholly and majority-owned subsidiaries, provides intelligent power and intelligent sensing solutions with a primary focus towards automotive and industrial markets to help its customers solve challenging problems and create cutting-edge products for a better future. The company operates under the onsemi brand.
The company utilizes its extensive range of power technologies to help address the growing power demands of AI and data centers. The company’s intelligent power technologies enable the electrification of the automotive industry that allows for lighter and longer-range electric vehicles, empowers efficient fast-charging systems and propels sustainable energy for the highest efficiency solar strings and industrial power. The company’s intelligent power solutions for the automotive industry allow its customers to exceed range targets with lower weight and reduce system cost through efficiency. The company’s intelligent sensing technologies support the next generation industry, allowing for smarter factories and buildings while also enhancing the automotive mobility experience with imaging and depth sensing that make advanced vehicle safety and automated driving systems possible.
Segments
The company operates into three segments: the Power Solutions Group (PSG), the Analog and Mixed-Signal Group (AMG), and the Intelligent Sensing Group (ISG).
PSG
This segment’s products include analog products; SiC products; discrete products; MOSFET products; power module products; Isolation products; memory products; gate driver products; and standard logic products.
ASG
This segment’s products include analog products; ASIC products; ECL products; foundry products / services; gate driver products; and LSI products.
ISG
This segment’s products include actuator drivers; complementary metal oxide semiconductor (CMOS) image sensors; image signal processors; and single photon detectors.
Business Strategy
The company is designing products in highly differentiated markets focused on customer needs while optimizing and right-sizing its manufacturing footprint to support growth with new product development and maintain gross margins through efficiencies.
Acquisition
On January 14, 2025, the company completed the previously announced acquisition of the Silicon Carbide Junction Field-Effect Transistor (SiC JFET) technology business from Qorvo US, Inc., and certain of its subsidiaries.
Revenue-Generating Activities
The company generates revenue primarily from the sale of semiconductor products to distributors and direct customers. The company also generates revenue, to a much lesser extent, from product development agreements and manufacturing services provided to customers. The company’s ability to offer a broad range of products, combined with its global manufacturing and logistics network, provides its customers with single source purchasing. In 2025, the company expects to include SiC JFET in its product portfolio within the PSG segment.
Products and Technology
PSG
PSG offers a wide array of discrete, module, and integrated semiconductor products that perform multiple application functions, including power switching, signal conditioning, and circuit protection. The trends driving growth within the company’s end-user markets are primarily higher power efficiency and power density in power applications, the need for greater functionality, and faster data transmission rates in all communications. Enhancement of the current electrical infrastructure driven by demand for green energy, electrification of powertrains in EVs and HEVs, and increased power demands from AI drive demand for the company’s highly efficient power switching products. The recent increase in the use of WBG MOSFETs and diodes, including SiC and IGBT, is further expanding the use of semiconductor products.
