We have described here what is avalanche breakdown and theory behind it. read more
Avalanche breakdown is a phenomenon that occur in both insulating and semiconducting materials. It is a form of electric current multiplication that can allow very large currents within materials which are otherwise good insulators. It is a type of electron avalanche. read more
"Avalanche breakdown is caused by impact ionization of electron-hole pairs.ÝWhile very little current flows under reverse bias conditions, some current does flow.ÝThe electric field in the depletion region of a diode can be very high. read more
The Avalanche Breakdown and Zener Breakdown are two different mechanisms by which a pn junction breaks. Equivalent circuit and V-I characteristics is shown. The Avalanche Breakdown and Zener Breakdown are two different mechanisms by which a pn junction breaks. read more
