A circuit for driving a gated p-n-p-n device comprises a p and/or n-gate electrodes provided on a p and/or n-gate regions of a p-n-p-n device, and a rectifying device provided between the p or n-gate electrode provided on a gate region which is higher in its impurity density than the other gate region and an anode or cathode electrode of the p-n-p-n device and/or a resistance means provided between the p or n-gate electrode provided on a gate region which is lower in its impurity density than the other gate region. In the circuit for driving a gated p-n-p-n device, excess carriers are expelled from the p and/or n-gate electrodes through the rectifying device and/or resistance means to the external of the p and/or n-gate regions.
