Overview

Wolfspeed Silicon Carbide Is Pushing Electric Vehicles Ahead Of The Curve

Build a better charging industry for tomorrow with Wolfspeed’s family of proven components and designs. Wolfspeed Silicon Carbide enables power efficiency, lower system costs, and smaller component sizes. Explore our modeling tools and reference designs to see how Wolfspeed Silicon Carbide can deliver exceptional performance in your EV designs.


Driving farther and faster to the future

Now more than ever, electric vehicles (EVs) are on the roads and on the minds of Wolfspeed engineers. We’ve expanded our portfolio of wide bandgap Silicon Carbide (SiC) devices to deliver high-voltage, high-current, and high-temperature components that are helping designers build the competitive and efficient automobiles that the market demands.

A Market in Motion

Wolfspeed launched the industry’s first Silicon Carbide (SiC) MOSFET in 2011 and has been leading the transformation from silicon to Silicon Carbide in EVs ever since. No longer constrained by the limitations of Si devices, EV designers embraced the faster switching speeds and greater power density that only Silicon Carbide MOSFETs and Schottky diodes enable, building smaller, lighter, and more efficient motors. Reducing power losses by nearly 80% also reduces consumers’ “range anxiety” by extending driving distance by up to 10%.

Wolfspeed offers the industry’s most comprehensive portfolio of high-performance, high-capability Silicon Carbide components, including our automotive-grade E-Series, a family of ruggedized devices which are the first commercially available Silicon Carbide MOSFETs and diodes to be AEC-Q101 automotive qualified and PPAP capable. The E-Series offers designers the highest available power density and can handle the harshest environments for both on-board and off-board automotive power conversion systems.
