This paper presents the performances expected by using SiC Mosfets for motor drive applications in High Temperature environment. Static and dynamic characterization of SiC Mosfet dice with suitable packaging has been realized with temperature ranging from +25deg C to +250 °C. A specific ageing setup has been built to evaluate the lifetime of the devices in switching conditions at T > 250deg C. The results perm it to conclude in the performances reachable at complete power inverter level.
