Abstract
In a general aspect, a silicon carbide (SiC) rectifier can include a substrate of a first conductivity type, a drift region of the first conductivity type, a junction field effect transistor (JFET) region of the first conductivity type, a body region of a second conductivity type, an anode implant region of the first conductivity type, and a channel of the first conductivity type. The channel can be in contact with and disposed between the JFET region and the anode implant region. A portion of the channel between the anode implant region and the JFET region can be disposed in the body region, The channel can be configured to be off under zero-bias conditions, and on at a positive turn-on voltage.
