Abstract

An integratable circuit configuration includes a first transistor of one conduction type having an emitter being acted upon by a first potential, a collector being acted upon by a second potential, a base, a base-to-collector path and a base-to-emitter path. A resistor is connected in parallel with the base-to-emitter path of the first transistor. A second transistor of the other conduction type is connected to the base of the first transistor for triggering. A diode may be connected in parallel with the base-to-collector path of the first transistor. The diode conducts in inverse operation for reverse current reduction during inverse operation of the first transistor. A third transistor may be connected to the first transistor instead of the diode and fourth and further transistors may also be connected to the first transistor.
