ABSTRACT:
The negative voltage transient associated with an inductive load of a circuit, is limited to a desired value while protecting other parts of the circuit from damage or improper operation, by providing a breakdown path, in the reverse direction, through at least one semiconductor junction. This junction may be the collector-to-base junction of a transistor which is employed to supply current to the inductor during another period in the operating cycle of the circuit.
