Avalanche BreakdownNew

Our Take

Avalanche breakdown is when a diode is reverse-biased so much (typically over 5V) that electrons start popping out of the valence band and bashing their way through the silicon lattice, knocking other electrons out of the valence band and basically creating an avalanche of electrons crashing their way through the depletion region and out the anode. This occurs in both "normal" and zener diodes.
