6.5-kV SiC MOSFET reaches 8-kV blocking
NoMIS Power has developed a 6.5-kV large-die SiC MOSFET that has demonstrated over 8 kV of blocking voltage, 90-mΩ on-resistance, and 55-A drain current. Based on the planar SiC technology used in its 3.3-kV devices, the 6.5-kV MOSFET extends the technology into the high-voltage class and provides a foundation for the company’s planned 10-kV MOSFETs and 20-kV SiC IGBTs.
NoMIS is sampling the 6.5-kV SiC MOSFET to U.S.-based customers, with standard-production devices scheduled for Q4 2026. The company plans to expand the 6.5-kV portfolio with additional on-resistance variants, small-die MOSFETs, hybrid junction-barrier Schottky FETs (JBSFETs), and standalone diodes for applications including HVDC power transmission, solid-state transformers, pulsed-power systems, rail traction, and megawatt-scale EV charging
The 6.5-kV devices build on the company’s 3.3-kV SiC MOSFET family, which is already in production, while 10-kV and higher-voltage MOSFETs, diodes, JBSFETs, and SiC IGBTs are in development.
