Wolfspeed’s Gen 4 MOSFET technology represents a paradigm shift in silicon carbide technology that puts three performance vectors into the center of every Gen 4-based design: holistic system efficiency, durability, and lower system cost. Engineered to simplify switching behaviours and operational challenges commonly experienced in high-power designs, Gen 4 charts a long-term roadmap across Wolfspeed’s product categories, including power modules, discrete components, and bare die products currently already available in the 750 V, 1200 V, and 2300 V classes. Gen 4 will deliver significant performance enhancements for designers of high-power automotive, industrial, and renewable energy systems, with key benefits including:
- Durability: Ensuring reliable performance, including a short-circuit withstand time of up to 2.3 µs to provide additional safety margin.
- Holistic System Efficiency: Delivering up to a 21 % reduction in on-resistance at operating temperatures for soft and hard switching application, while hard switching applications benefit from up to 15 % lower switching losses.
- Lower System Cost: Streamlining design processes to reduce system costs and development time.
