Question

Mention two information that you can get fromV-I characteristics of a p-n junction diode.

Hint:

The threshold voltage is a critical characteristic for understanding when a diode starts to conduct in the forward direction, while the reverse breakdown voltage helps assess the diode’s durability under reverse bias.

Answer 1

From the V-I characteristics of a diode, you can obtain the following information:
(A) The threshold voltage (or cut-off voltage), which is the minimum voltage required for the diode to start conducting in the forward direction.
(B) The reverse breakdown voltage, which is the voltage at which the diode begins to conduct in the reverse direction, potentially damaging the diode.
