Silicon carbide (SiC) offers significant advantages for power-switching devices because the critical field for avalanche breakdown is about ten times higher than in silicon. SiC power devices have made remarkable progress in the past five years, demonstrating currents in excess of 100 A and blocking voltages in excess of 19000 V. In this paper we describe the latest progress in three classes of SiC devices: diodes (p-i-n and Schottky), transistors (junction field-effect transistor, metal-oxide-semiconductor field-effect transistor, and bipolar junction transistor), and thyristors (gate turn-off).
