Abstract
A semiconductor device includes: a semiconductor body having an active region and a substrate region beneath the active region; a bidirectional switch having first and second gate structures configured to control a conductive state of a channel in the active region, and first and second input-output terminals electrically connected to the channel; and a passive discharge circuit in parallel with the bidirectional switch and configured to utilize a fraction of a voltage across the first and second input-output terminals to switch on a transistor device that electrically connects the substrate region to the input-output terminal at the lower potential during an off-state of the bidirectional switch and during ZVS (zero-voltage switching) transition periods.
