Wolfspeed, Inc. has announced a new line of 1200V Silicon Carbide (SiC) six-pack power modules that significantly raise the bar for high-power inverter performance. Leveraging Wolfspeed’s Gen 4 SiC MOSFETs and an advanced YM package design, these modules deliver three times the power cycling capability at operating temperature compared to other solutions in the same footprint, and enable up to 15% more inverter current.
The modules incorporate innovations like sintered die attach, epoxy encapsulation, and copper clip interconnects, resulting in a robust system with high durability. These design enhancements allow the modules to achieve superior power cycling endurance—an area traditionally limited by material and thermal fatigue—while maintaining high levels of electrical performance.
Performance improvements include a 22% lower RDS(on) at 125°C, a 60% reduction in turn-on energy losses (EON), and significantly improved diode behavior with 30% lower switching losses and 50% lower VDS overshoot during reverse recovery. These gains support higher system efficiency and improved thermal management under heavy load conditions.
The modules are drop-in compatible with existing IGBT module architectures, eliminating the need for redesign and simplifying integration. Their packaging design reduces assembly complexity by removing the need for laser-welded terminals or intricate cold plate mounting, making them attractive for applications in electric mobility, industrial drives, and heavy-duty vehicle platforms.
Wolfspeed’s new power modules are designed to support extended service life and reduced operational cost, addressing key industry concerns such as maintenance, energy efficiency, and sustainability. Sampling is currently underway, with general availability through distributors expected in early 2026.
