。[Claims for Utility Model Registration] In a composite semiconductor device comprising a Darlington connection of a main transistor and an auxiliary transistor that drives the transistor, the base current of the transistor is blocked in parallel with the base-emitter circuit of the auxiliary transistor. A series circuit is connected between a diode with a polarity of 0 and a Zener diode with a polarity that blocks the forward current of the diode or a voltage blocking means having characteristics equivalent to that of the Zener diode, and at least a capacitor is connected in parallel with the series circuit. Alternatively, a composite semiconductor device characterized in that a series circuit of the capacitor and an impedance is connected.
