Abstract

Electrical characteristics of 4H-SiC Schottky barrier diodes, based on buried grid design are presented. The diodes, rated to 1200V/10A and assembled into high temperature capable TO254 packages, have been tested and studied up to 250°C. Compared to conventional SiC Schottky diodes, Ascatron's buried grid SiC Schottky diode demonstrates several orders of magnitude reduced leakage current at high temperature operation.
