ABSTRACT:
A semiconductor switch circuit of field-drive type includes a bipolar component having forward blocking and reverse blocking junctions, and p-channel and n-channel IGPETS connected across the bipolar component so as to short-circuit its forward blocking junction. The switch circuit operates to turn on or off in response to the voltage signal to the gate circuit which is isolated from the bipolar component, irrespective of the polarity of a voltage applied across the bipolar component.
