ABSTRACT:
Disclosed is a protection circuit for protecting a rectifier circuit from electrostatic pulses. The circuit employs a first bypass capacitor that is connected between positive and negative power lines to bypass electrostatic pulses that have a rise time that allows the diodes to conduct and prevent damage to the diodes as a result of reverse biasing, and a second bypass capacitor that is connected between an input node and the negative power line to discharge the electrostatic pulses that have a rise time that is faster than the turn-on times of the diodes. Connection of the bypass capacitors at locations close to the rectifying diodes minimizes the effects of stray inductance that affects the operation of the rectifier circuit in response to fast rise time transient pulses.
