Abstract: This controlled electronic switching device for the suppression of transients can change over from a non-conductive state to a conductive state at lower triggering current levels than conventional devices while retaining unaltered its response characteristics to variations in the voltage applied thereacross. The device comprises a main switch which is triggered by a parallel-connected auxiliary switch having smaller junction areas and a higher capacitive current shunt resistance (resistance between base and emitter) than the main switch, thereby it turns on at lower control currents from the gate electrode for a given response to voltage variations.
