What does breakdown mean physically?
I saw this in wikipedia:
The avalanche process occurs when the carriers in the transition region are accelerated by the electric field to energies sufficient to free electron-hole pairs via collisions with bound electrons.
Say I have a lightly doped Germanium pn junction, will I be able to use it again or throw it away once Avalanche breakdown take place?
And also what happens in case of Zener breakdown? I know it requires highly doped pn junction and not so much pot diff..
