7. It is very important that the PIV rating of a diode be checked when choosing a diode
for a particular application. Simply determine the maximum voltage across the diode
under reverse-bias conditions , and compare it to the nameplate rating. For the typical
half-wave and full-wave bridge rectifiers, it is the peak value of the applied signal. For
the CT transformer full-wave rectifier, it is twice the peak value (which can get quite
high).
