ABSTRACT:
An electronic device is protected from excessive A. C. voltages by a diode in series with the A. C. signal path which is forward biased from a shunt D. C. power supply for passing desired A. C. signals without distortion and which is reverse biased by a series capacitor which is charged through a shunt threshold device whenever the A. C. voltage exceeds a predetermined level and is discharged through a shunt path thereafter.
