breakdown voltage and avalanche voltage

[PG1995]

Hi :smile:

Okay, breakdown voltage is a term for voltage at which a diode starts to conduct when it is reverse biased. In case of forward biasing the voltage at which the diode conducts is called knee voltage (in case of Silicon voltage it's 0.7V).

What is term for voltage limit when the diode will be destroyed? Destroying voltage?

I think there is no thing such as "avalanche voltage" rather the proper term is "avalanche effect". Please let me know your opinion.

Thank you for your time and help.

Avalanche breakdown doesn't necessarily involve damage to a semiconductor device, and damage isn't primarly a matter of a voltage level in this case. It's rather current respectively current distribution. You have to refer to the device specification.
