Q.  Breakdown devices belonging to the category of solid-state devices are basically dependent on the phenomenon of __________
- Published on 20 Oct 15

a. Zener Breakdown
b. Avalanche Breakdown
c. PN Junction Breakdown
d. All of the above

ANSWER: Avalanche Breakdown
 
Breakdown devices are specifically renowned by thyristor which act as a semiconductor switch whose bistable action is dependent on P-N-P-N regenerative feedback mechanism.

UJT, LASCR, Diac, Triac, SCR & SCS are some of the widely applicable breakdown devices whose working strategy is confined by the consequences of an avalanche breakdown despite of Zener and PN junction breakdown phenomena which occurs specifically in cases of Zener & PN junction diodes respectively.

These devices performs the function of latching since they consist of two or more junction & can be easily switched ON or OFF at instantaneously rapid speed.
