Wolfspeed Unveils 10kV SiC MOSFET with 158,000-Year Lifetime, Cuts System Costs 30%

WOLFWOLF

Wolfspeed launched the industry's first commercially available 10 kV silicon carbide power MOSFET featuring a predicted 158,000-year lifetime at 20 V gate bias. The device promises to cut system costs by roughly 30%, boost power density over 300%, and halve thermal requirements for grid and AI data center applications.

1. Industry-First 10kV SiC MOSFET Launch

Wolfspeed introduced the CPM3-10000-0300A, the first commercially available 10 kV silicon carbide power MOSFET. This launch marks a milestone in high-voltage SiC technology, enabling voltage ratings previously unattainable with SiC power devices.

2. Performance and Reliability Highlights

Intrinsic time-dependent dielectric breakdown (TDDB) testing predicts a 158,000-year lifetime at a continuous 20 V gate bias, while solving bipolar degradation and maintaining body-diode performance. The device achieves a sub-10 ns rise time, supporting reliable operation in demanding pulsed-power and solid-state transformer applications.

3. Architectural Benefits and Cost Reductions

Thanks to the 10 kV rating, system architectures can consolidate multi-cell designs into fewer modules and simplify three-level inverters to two-level topologies, cutting system costs by approximately 30%. Higher switching frequencies (600 Hz to 10,000 Hz) drive over 300% improvement in power density and reduce thermal management requirements by up to 50%.

4. Market Applications and Commercial Availability

The new MOSFET is available now for customer sampling and qualification, targeting grid modernization, mid-voltage UPS, wind power, solid-state transformers, AI data centers, geothermal pulsed power, and semiconductor plasma etching. Customers prototyping at 10 kV can accelerate time to market by transitioning to this production-ready device.
