JEE Main · 2024 · 09 Apr 2024 · Shift 2 · Semiconductors

The

I - V

characteristics of an electronic device shown in the figure. The device is :

(A)a solar cell
(B)a transistor which can be used as an amplifier
(C)a zener diode which can be used as voltage regulator✓ Correct
(D)a diode which can be used as a rectifier

Answer: (C)

Solution

The I–V curve shown is characteristic of a device with a sharp breakdown/reverse current at a fixed voltage that then holds nearly constant voltage — this is the reverse-bias breakdown behaviour of a Zener diode, which is used as a voltage regulator.
