Wolfspeed has announced the release of its 1200-volt silicon carbide (SiC) six-pack power modules, targeting high-power inverter applications for electric vehicles and industrial machinery. The new modules utilize Wolfspeed’s Gen 4 SiC MOSFET technology combined with updated packaging to deliver what it claims is three times the power cycling capability at operating temperature compared to competitive options and 15 percent higher inverter current in an industry-standard footprint.
Technical highlights include a 22 percent reduction in drain-source on-resistance at 125°C compared to the prior generation. The modules also feature approximately 60 percent lower turn-on energy across operating temperatures, a soft-body diode design for 30 percent lower switching losses, and 50 percent lower VDS overshoot during reverse recovery events, based on Wolfspeed’s measurements against its previous generation.
The packaging approach uses sintered die attach, epoxy encapsulant and copper clip interconnects, which together enable the threefold increase in power cycling relative to leading competitor devices in the same physical format, according to the company. The modules’ industry-standard casing allows for drop-in replacement of IGBT modules, reducing the need for complex redesigns and making integration into existing electrified vehicle architectures more straightforward. Compatibility with standard system components such as capacitors, cooling plates, gate drivers and current sensors is maintained, and assembly is simplified by removing requirements for power terminal laser welding and complex coldplate mounting.
Wolfspeed notes that these modules are designed for electric vehicle OEMs as well as heavy-duty, construction, and agricultural vehicle manufacturers who prioritize reliability, power density, and reduced maintenance. Other industrial inverter markets are also directly targeted. The 1200-volt SiC six-pack modules are currently available for sampling, with full distribution availability expected in early 2026.
“These modules provide a means for electric mobility OEMs to take a quantum leap forward in technology,” said Dr. Cengiz Balkas, Chief Business Officer at Wolfspeed. “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.”
