Patent ID: 8824177

Claim:
A semiconductor device comprising: a switching transistor; and a recovery diode and a snubber device mounted on a single conductive substrate on which said switching transistor is also mounted, wherein said snubber device includes: a SiC-MOSFET connected between an output terminal and a reference terminal of said switching transistor; a Zener diode connected between a gate terminal and a drain terminal of said SiC-MOSFET; and a resistor connected between said gate terminal and a source terminal of said SiC-MOSFET, the reference terminal of said switching transistor, the source terminal of said SiC-MOSFET, and an anode terminal of said recovery diode are commonly connected, and wherein current is permitted to pass in both directions between the Zener diode and the gate terminal of said SiC-MOSFET.
