SiC pushes the temperature barrier of semiconductors upwards, clearly over 300deg C. JFET are available as engineering samples from SiCED. This paper present the characterisation of such devices: gate behavior, power losses. A demonstrator inverter leg is experimented switching 15A under 540V cooled at 250deg C.
