A circuit is disclosed comprising a switching rectification diode for rectifying a reverse transient voltage, a charging capacitor for charging an output voltage from the switching rectification diode thereon, and a discharging resistor connected in parallel to the charging capacitor, for discharging the voltage charged on the charging capacitor. With no limitation in frequency band, the circuit can effectively remove an instantaneous reverse transient voltage such as a reverse surge voltage or a reverse ringing voltage which results from abrupt variations in output voltages from preceding circuits. In addition, the circuit can stabilize operation of the associated device despite of heat so that individual components can be set to lower reverse withstand voltages.
