The main difference between Zener breakdown and avalanche breakdown is their mechanism of occurrence. Zener breakdown occurs because of the high electric field. The avalanche breakdown occurs because of the collision of free electrons with atoms. Both these breakdowns can occur simultaneously.
Nov 30, 2023 · The Zener breakdown is observed because of the reverse saturation current from free electrons generated by the reverse biased junction whereas the Avalanche breakdown is observed because of the current generated by the high electric field produced by applying high reverse voltage across diode.
An electrical breakdown takes place due to two types of occurrences like Zener as well as an avalanche. The main difference between Zener breakdown and Avalanche breakdown is the occurrence of their mechanism due to the high electric field.
The Zener and Avalanche breakdown both occur in diode under reverse bias. The avalanche breakdown occurs because of the ionisation of electrons and hole pairs whereas the Zener breakdown occurs because of heavy doping. These are explained below in details.
Sep 2, 2022 · The most significant difference between the two is that the Zener breakdown occurs at a relatively low reverse voltage and is reversible, while the avalanche breakdown occurs at a higher reverse voltage and it is irreversible. Hence, a Zener breakdown does not damage the diode, whereas an Avalanche breakdown may damage the diode permanently.
Dec 28, 2018 · In this video, the avalanche breakdown and Zener breakdown effects in the PN junction diode have been explained. By watching this video, you will learn the f...
Difference Between Avalanche & Zener Breakdown. One of the major difference between the Avalanche and the Zener breakdown is that the Avalanche breakdown occurs because of the collision of the electrons, whereas the Zener breakdown occurs because of the high electric field.
Zener Breakdown and Avalanche Breakdown are two primary phenomena associated with the breakdown of diodes under high reverse bias conditions. Depending on the diode’s application, both mechanisms can represent failure modes or useful functions. What is Zener Breakdown?
The crucial difference between the Zener and Avalanche breakdown is the operating mechanism. Zener breakdown occurs when the high electric field is created across the junction and Avalanche Breakdown occurs in the device due to the collision of electrons moving at high speed.
May 25, 2021 · Avalanche Breakdown. Zener breakdown occurs due to a high electric field which causes electrons in the valance band to come into the conductance band. Avalanche breakdown occurs due to the collision of free electrons and atoms due to a high electric field.
