Peak inverse voltage
In addition to forward voltage drop (Vf) and peak inverse voltage (PIV), there are many other ratings of diodes important to circuit design and component selection.

What is the peak forward current through each diode in figure? +5 V +50 V Vin R Vin R 47 N V out out 3.3 kN -5 V -50 V (a) (b)The above answers state that PIV is 2Vp because the voltage from the capacitor and the maximum negative voltage from the source are equal in magnitude and across the diode at the same time. However, this diagram shows the capacitor voltage is only equal in magnitude to Vp at the same peaks as the waveform without the capacitor (the top of the ...These are designed from Si & distinguished through a quite large PN junction surface so, it results in high capacitance in reverse-bias conditions. The two rectifier diodes are connected to high-voltage supplies in series to enhance the rating of PIV (peak-inverse-voltage) for the combination.
We would like to show you a description here but the site won't allow us.The main considerations for a rectifier circuit are the maximum average forward current and the peak inverse voltage (PIV), or maximum repetitive reverse voltage (V RRM). The maximum average forward current is roughly 1/2(V av /R L), where V av is the average voltage and R L is the load resistance, since each diode conducts only half the time ...The value of peak inverse voltage is similar to the peak value of an input voltage and the diode should have the ability to bear this repetitive reverse voltage. In the given figure, you can see that, the extreme value of reverse voltage denoted as (PIV) exits at the peak of every negative repetition of the input voltage when the diode is in ...Aside from the fact that the first equation should show Vpp for the 2nd and 3rd “Vp” as: Vp=1/2 * Vpp = 0.5 * Vpp, for completeness and clarity the 2nd formula which shows that Vp is: 1.414 * RMS, it should be shown that the RMS voltage is approximately equal to 0.7071 * Vp, and in the 3rd equation it should be shown that the average voltage is approximately 0.637 * Vp.
