Webb6 apr. 2024 · Detailed Solution. Peak inverse voltage rating of a diode may be defined as the maximum value of the reverse voltage that a PN-junction (or diode) can withstand without damaging (or destruction). It is the peak inverse voltage rating (PIV) of a diode. Webb23 jan. 2024 · PIV is the maximum inverse voltage that a diode can handle before having a breakdown. For a half wave rectifier, in the negative half of the cycle the diode acts as a open circuit so the applied voltage signal with Vm as peak value appears on the terminal of that diode, and so the PIV of that diode becomes Vm.
