breakdown voltage and avalanche voltage

Hi

There is a breakdown voltage and avalanche voltage for a diode. What's the difference? I couldn't really find any distinct difference. Could you please help me? Thanks.

Not all breakdown occurs due to an avalanche mechanism. Some of it is due to the so-called Zener breakdown, although confusingly most of the devices referred to as "Zener" diodes are actually avalanche diodes (if their breakdown voltages are more than about 6V). http://people.seas.harvard.edu/~jones/es154/lectures/lecture_2/breakdown/breakdown.html

Thank you, Adjuster.

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.

For the "normal" diode the breakdown voltage will destroyed the diode.
Unless we limit the breakdown current to such a values that power dissipation in the diode is less the max allow power.
