What Is Breakdown Voltage In Pn Junction Diode

What Is Breakdown Voltage In Pn Junction Diode. A zener diode in its reverse bias, exhibits a controlled breakdown voltage and it allows the current flow to keep the value of voltage across that zener diode close to the zener breakdown voltage value. The breakdown voltage is a key parameter of power devices.

In general, the avalanche breakdown is produced when the high reverse voltage is applied across the diode. When this applied reverse bias voltage is increased gradually at a certain point a rapid increase in the reverse current can be observed.

If there is an increase in the applied voltage then there is an increase in the electric field near the junction. A zener diode in its reverse bias, exhibits a controlled breakdown voltage and it allows the current flow to keep the value of voltage across that zener diode close to the zener breakdown voltage value.
