Abstract :
We report on the development of the first 1 cm × 1 cm SiC thyristor chip capable of handling 1770 V. This demonstrates the present quality of the SiC substrate and epitaxial material. A forward drop of 4 V at 100 A and 200°C was measured. The turn-on delay is found to be a strong function of the gate current. At a gate current of 1.5 A, the turn-on delay of 72 ns is observed for anode to cathode current, IAK=10 A. The turn-on rise time is a strong function of the anode to cathode voltage, VAK. At VAK=500 V, the turn-on rise time was 26 ns for IAK=10 A.
