What is an avalanche breakdown voltage?

This is the voltage level across a semiconductor at which an “avalanche” breakdown occurs. The amount of current that flows increases very abruptly so you cannot get much more voltage across the device. read more

Avalanche breakdown voltage : It is the voltage at which the junction of the diode breaks when it is connected in reverse bias condition. Forward bias : Anode connecting to +ve terminal of the battery & Cathode is connecting to -ve terminal of the supply. read more

The voltage at which the breakdown occurs is called the breakdown voltage. There is a hysteresis effect; once avalanche breakdown has occurred, the material will continue to conduct even if the voltage across it drops below the breakdown voltage. read more

The voltage at which this occurs is the breakdown voltage. Avalanche breakdown occurs when a charged particle is accelerated to a high enough velocity (and thus energy) to ionize an atom in the medium, creating a new particle that will accelerate and repeat the process. This is called impact ionization. read more
