The highly doping level of the base region of COOLMOS™ transistors allows higher temperature operations than with conventional silicon transistors having the same blocking voltage. In this paper, the temperature influence on different SiC Schottky diodes and Silicon COOLMOS™ transistors characteristics is discussed. Comparisons are made between SiC Schottky diodes and Si PIN diodes and beween IGBTs, low voltage MOSFET and COOLMOS™ at high temperature. Results on the leakage current indicate the ability of SiC Schottky diodes and Si COOLMOS™ transistors to be used at temperature about 200°C. The paper will present results on the behaviour of SiC schottky diodes and COOLMOS™ transistors in the on-state and in switching operations. Switching behaviour is analysed in a buck-chopper working in single shoot condition. Results show that temperature has a great influence on the on-state performances of the tested devices, but that the switching performances of SiC Schottky diodes and COOLMOS™ transistors are not significantly modified at elevated temperatures.
