Advanced Gen 4 Power Modules Deliver 3X Power Cycling Capability and 15% Higher Current Capability

Wolfspeed, Inc., a global leader in silicon carbide technology, today announced its new 1200V SiC six-pack power modules that redefine performance benchmarks for high-power inverters. By combining its latest advanced Gen 4 SiC MOSFET technology and innovative packaging, Wolfspeed’s modules deliver three times more power cycling capability at operating temperature than competing solutions, and 15% higher inverter current capability in an industry-standard footprint.

"These modules provide a means for electric mobility OEMs to take a quantum leap forward in technology," said Dr. Cengiz Balkas, Wolfspeed Chief Business Officer. "We took proven, well-rounded switching performance made possible with our Gen 4 MOSFETs and turned further knobs with our YM package to greatly improve power cycling – one of the biggest performance hurdles a power designer can face. In doing so, we're delivering the reliability, efficiency, and power density that heavy-duty, construction and agricultural vehicles demand.”

Unmatched System Durability and Lifetime Confidence

The new modules incorporate state-of-the-art packaging technology including sintered die attach, epoxy encapsulant material, and copper clip interconnects, enabling 3X more power cycles than best-in-class competitor devices in the same footprint. In this new white paper learn more about Wolfspeed's power cycling and lifetime modeling approach.

Greater Ampacity for Industrial Inverters

The modules achieve a 22% R_DS(ON) improvement at 125°C compared to the previous generation, while reducing turn-on energy (E_ON) by approximately 60% across operating temperatures. Additionally, the soft-body diode enables 30% lower switching losses and 50% lower V_DS overshoot during reverse recovery compared to previous generation.

Simplified System Integration

The modules' industry-standard packaging enables seamless adoption without complex redesign, serving as a direct replacement for IGBT solutions in existing system architectures. With simpler assembly requirements, the modules eliminate the need for power terminal laser welding and complex coldplate mounting while maintaining compatibility with traditional power ecosystems including capacitors, cooling solutions, gate drivers, and current sensors.

“These modules' enhanced power cycling capabilities and efficiency translate directly to reduced maintenance costs, extended vehicle operational life, and improved energy efficiency - addressing critical concerns for fleet operators and OEMs focused on total cost of ownership and sustainability goals,” – notes Guy Moxey, Vice President and General Manager for Industrial and Energy.

Availability

The 1200V SiC six-pack power modules are now available for customer sampling with full availability at distributors in early 2026.
