Zener diode has higher dopant density as compared to ordinary p-n junction diode. How does if effect (i) the width of depletion layer and (ii) the junction field?
Text Solution
Verified by Experts
(i) Due to higherdopant density in the zener diode, the width of the depletion layer decreases. (ii) Due to higher dopant density in the Zener diode, the junction field (E) increases, since the width of depletion layer decreases `[:' E=V_B//d]`
