Peak inverse voltage rating refers to the maximum voltage a diode can withstand in the reverse-bias direction without suffering from damage. It is also known as the peak reverse voltage or reverse breakdown voltage. Other synonyms for peak inverse voltage rating include reverse voltage rating, reverse voltage limit, reverse voltage drop, reverse voltage breakdown, reverse bias voltage, reverse recovery voltage, and reverse blocking voltage. These terms all refer to the same criterion: the voltage level that, when exceeded in the reverse-bias direction of the diode, causes the depletion region to break down and current to flow in the opposite direction. Proper understanding and selection of the proper peak inverse voltage rating for a diode is crucial for the safe and reliable operation of electrical circuits.
