ABSTRACT:
A driver circuit for a bipolar Darlington power transistor includes a current clamping device which is provided between the base and emitter of said transistor and makes the base-emitter path of said transistor operate at a shallow saturated region; and a cut off device which is provided at the side of said emitter and cuts-off said transistor in response to a signal given from a driving power source.
