Reverse Breakdown Zener Of Diodes
Apr 10, 2017

Reverse breakdown by mechanism is divided into Zener breakdown and avalanche breakdown two conditions. In the case of high doping concentration, because the barrier area is very small, the reverse voltage is larger, the damage to the potential barrier zone of the covalent bond structure, so that the valence electrons out of bond bondage, resulting in electron-hole pairs, resulting in a sharp increase of current, this breakdown called Zener breakdown. If the doping concentration is low, the barrier width is wider, and the zener breakdown is not easily produced.
