Avalanche breakdown - Wikipedia

The Zener effect is distinct from avalanche breakdown. Avalanche breakdown involves minority carrier electrons in the transition region being accelerated, by the electric field, to energies sufficient for freeing electron-hole pairs via collisions with bound electrons. The Zener and the avalanche effect may occur simultaneously or independently of one another. In general, diode junction breakdowns occurring below 5 volts are caused by the Zener effect, whereas breakdow… WebMay 24, 2024 · Avalanche diodes, like Zener diodes, are designed to break down and conduct very high currents at a specific reverse-bias voltage. This behavior is referred to as the avalanche effect . Similar to Zener diodes, which are somewhat restricted in the maximum breakdown voltage range, avalanche diodes are available with breakdown … irca bergamo https://soterioncorp.com
