What is the importance of PIV rating?

Thus, PIV rating is important to know how much maximum voltage can be applied across the diode safely without damaging the diode. PIV rating is different for different diodes and It is specified in the data given by the manufacturer about the diode.

How is PIV rating calculated?

What is Peak Inverse Voltage?

1. Peak inverse voltage in the diode is the peak value of the inverse voltage across the diode in reverse bias condition. Consider the circuit shown below to calculate the PIV of the silicon diode or peak inverse voltage of the diode.
2. PIV of Diode = Esm.
3. PIV = 2Esm – 0.7.

What is PIV of silicon diode?

Peak Inverse Voltage (PIV) = Maximum reverse voltage allowed. There is a forward turn on voltage – The silicon diode will only allow current through it if there is 0.7V flowing through it (i.e. it requires 0.7V to turn itself on).

What is the maximum value of PIV for germanium?

For example, the PIV ratings of silicon diodes are in the neighbourhood of 1000V whereas the PIV ratings of germanium diodes are close to 400V. The disadvantage of silicon as compared to germanium is that potential barrier of silicon diode (0.7V) is more than that of germanium diode (0.5V).

What is the PIV rating of bridge rectifier?

The peak inverse voltage PIV is the maximum reverse voltage that can be applied to the diode. The peak inverse voltage of the transformer is 2Vp.

What is mean by PIV rating of a diode Mcq?

Explanation: PIV stands for Peak Inverse Voltage. It is the maximum reverse bias voltage which a diode can bear without breakdown. Explanation: PIV rating indicates the maximum allowable reverse bias voltage which can be safely applied to a diode.

What is the PIV rating of diode in bridge rectifier?

One of the most popular applications of the diode is rectification. The rectifier is a device that converts an alternating current (AC) to pulsating direct current (DC)….Transformer Utilization Factor of Bridge Rectifier.
