Vedclass · Answer

(A) $Zener$ diode is a specially designed $pn$ junction diode that is heavily doped to operate in the reverse breakdown region.In forward bias, it behaves like an ordinary $pn$ junction diode, conducting current once the threshold voltage is reached.In reverse bias, once the voltage across the $Zener$ diode reaches its $Zener$ breakdown voltage $(V_Z)$, the current increases significantly while the voltage across it remains nearly constant.This property allows the $Zener$ diode to function as a voltage regulator in the reverse bias region.
