Avalanche breakdown in zener diode is ______(a) electric current multiplication takes place(b) phenomenon of voltage multiplication takes place(c) electrons are decelerated for a period of time(d) sudden rise in voltage takes place.The question was posed to me in an online quiz.I would like to ask this question from Breakdown Diodes in division Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer»

The correct choice is (a) ELECTRIC current multiplication takes place

The explanation is: The carriers in TRANSITION region are accelerated by electric field to ENERGIES. That energies are sufficient to CREATE electron current multiplication. A single carrier that is energized will collide with another by gaining energy. Thus an avalanche multiplication takes place.
