1000v
At 1000 VDC, conduction losses are the primary source of heating versus switching losses. Regardless, under these conditions the Wolfspeed SiC MOSFET is still operating at 15-20o lower than the silicon MOSFET. As before, under these operating parameters, the Wolfspeed device can safely operate without a heatsink. At 80˚C, it is only running at roughly 1/2 of the maximum junction temperature.
