Company Overview

ON Semiconductor Corporation, operating under the brand onsemi, is a global semiconductor manufacturer specializing in power management, analog, and sensing technologies. The company operates primarily within the automotive, industrial, energy infrastructure, and cloud/communications industries, providing semiconductor solutions that enable energy efficiency, electrification, and intelligent power control. Its core offerings are used in applications such as electric vehicles (EVs), advanced driver-assistance systems (ADAS), factory automation, renewable energy systems, and data center power architectures.

Founded in 1999 through the spin-off of Motorola’s Semiconductor Components Group, ON Semiconductor evolved from a diversified commodity-focused chip supplier into a more specialized provider of high-value, application-specific solutions. Over the past decade, the company has strategically repositioned itself toward structurally growing end markets, particularly automotive and industrial, emphasizing long product lifecycles, tighter customer integration, and higher margins. Its differentiated positioning centers on vertically integrated manufacturing and deep expertise in power semiconductors and sensing technologies.

Business Operations

onsemi reports its operations across three primary business segments: Power Solutions Group, Advanced Solutions Group, and Intelligent Sensing Group. The Power Solutions Group is the company’s largest revenue contributor, focused on power discretes, power modules, and silicon carbide (SiC) devices used in EV powertrains, charging infrastructure, and industrial power systems. The Advanced Solutions Group provides analog, mixed-signal, and interface solutions for automotive and industrial applications, while the Intelligent Sensing Group specializes in image sensors and related technologies used in automotive vision systems, industrial imaging, and select consumer and medical applications.

The company generates revenue through direct sales to original equipment manufacturers (OEMs) and tier-one suppliers, particularly in automotive and industrial markets. onsemi maintains a vertically integrated manufacturing model, owning and operating a global network of wafer fabrication facilities, assembly, and test operations. This control over manufacturing is a key operational asset, enabling supply assurance and cost optimization. The company also maintains long-term supply agreements with strategic customers and collaborates closely with ecosystem partners across the automotive and energy value chains.

Strategic Position & Investments

onsemi’s strategic direction is focused on accelerating growth in electrification and automation while improving profitability through portfolio simplification and manufacturing optimization. A central pillar of this strategy is investment in silicon carbide (SiC) technology, which is critical for EVs, renewable energy, and high-efficiency power applications. The company has made significant capital investments to expand internal SiC crystal growth, wafer fabrication, and device manufacturing capacity.

Key acquisitions have supported this strategy, most notably the acquisition of GT Advanced Technologies, which strengthened onsemi’s vertical integration in SiC substrate production. The company has also divested non-core and lower-margin product lines to sharpen its focus on automotive and industrial end markets. Emerging areas of investment include advanced power modules, intelligent power integration, and next-generation automotive sensing platforms, aligning with long-term trends in electrification and autonomous systems.

Geographic Footprint

onsemi is headquartered in Phoenix, Arizona, and operates globally across North America, Europe, and Asia-Pacific. The company maintains manufacturing, design, and sales operations in key semiconductor hubs, including the United States, Japan, South Korea, China, Malaysia, Vietnam, Czech Republic, and Slovakia. This global footprint supports both regional customer engagement and supply chain resilience.

Revenue is geographically diversified, with a significant portion generated from international markets, particularly Asia-Pacific and Europe, reflecting the concentration of automotive and industrial manufacturing in those regions. onsemi’s global operations enable it to serve multinational customers while participating in region-specific investments tied to automotive electrification, industrial automation, and energy infrastructure development.

Leadership & Governance

onsemi is led by an experienced executive team with deep expertise in semiconductors, manufacturing, and global operations. The leadership emphasizes disciplined capital allocation, operational execution, and long-term value creation, with a stated focus on sustainability, energy efficiency, and customer-centric innovation.
