Abstract
A four layer insulated gate controlled semiconductor device has a range of anode-cathode currents over which gate control potentials will extinguish such anode-cathode current. Coupling circuitry for limiting the rate of change of turn-off gate control potential to the gate of the device enhances the range of anode-cathode current over which control is maintained.
