Silicon carbide device maker Wolfspeed has introduced its new Gen 4 technology platform, to simplify switching in high-power designs such as EV powertrains, renewable energy systems and battery energy storage systems.
Wolfspeed’s Gen 4 platform was designed to improve system efficiency and prolong application life, even in harsh environments, while helping to reduce system cost and development time. The technology aims to deliver performance enhancements for designers of high-power automotive, industrial and renewable energy systems.
Gen 4 delivers up to a 21% reduction in on-resistance at operating temperatures and up to 15% lower switching losses compared to the previous generation of products. It includes a short-circuit withstand time of up to 2.3 µS to provide an additional safety margin.
Wolfspeed’s Gen 4 products are available in 750 V, 1,200 V and 2,300 V nodes. There are options for power modules, discrete components and bare die products. New product introductions, including additional footprints and RDSON ranges, will be available throughout 2025 and early 2026.
“Our Gen 4 platform will be delivered via our highly efficient 200 mm wafers, which will enable us to deliver products on a large scale and high level of yield,” said Wolfspeed Executive Chairman Tom Werner.
