ABSTRACT:
An integrated switching device has a switching IGFET connected between a pair of main terminals, a protector IGFET connected between the drain and gate electrodes of the switching IGFET, and a gate resistor connected between a main control terminal and the gate electrode of the switching IGFET. The protector IGFET has its gate electrode connected to the source electrode of the switching IGFET. The protector IGFET turns on in response to an application of a verse voltage to the switching IGFET thereby protecting the same from a reverse current flow.
