Reliable Supply of Silicon Carbide (SiC)

Continuous Supply of Confidence

That’s the onsemi difference.

Let's Talk

You need a reliable SiC partner to accomplish your product development and growth objectives. That partner should have a leading edge technology roadmap, and a proven reputation for product performance. After all, maintaining control over supply, quality, cost, efficiency and supply chain is challenging with SiC.

That is onsemi.

onsemi is the premier long-term partner for SiC. With our reliable, end-to-end supply chain, deep application expertise, and broad EliteSiC portfolio of market-specialized solutions, you reach your design goals more confidently, with less risk, and greater control.

The onsemi Difference

Reliable Supply

From substrates to assembly to packaging, we offer a vertically integrated SiC manufacturing solution that ensures you have a reliable supply of SiC.

Competitive Advantage

With our deep application expertise in EV (on-board and off-board) and industrial, along with system level simulation tools, you count on us to deliver innovative solutions that provide you a competitive edge.

Specialized Solutions

Leveraging die and package technologies, our unique and broad EliteSIC product portfolio, we deliver the market- specialized solutions (die, devices, packages) you need—when you need them.

Leading With Die Performance.
Differentiating With Packaging Innovation.

Semiconductor manufactures that lack the required SiC history and packaging expertise struggle to achieve their desired results. They struggle to get the heat out of their devices, for instance. They struggle to reduce parasitics to desirable levels. And they never achieve the performance they are after—such as vehicle range and system efficiency.

At onsemi, optimized SiC solutions are in our DNA. Our concurrent development of dies and packages creates optimized solutions for our customers. We deliver advanced packaging materials and world-class thermal performance.

Markets We Serve


onsemi utilizes decades of R&D of SiC technology to create a revolutionary wide bandgap product family. The EliteSiC power modules for traction inverters offers bare die solutions, gel-encapsulated case modules, and transfer molded modules, all incorporating full SiC MOSFETs.
