Question

When temperature increases, reverse saturation current _________

(a) Increases

(b) Decreases

(c) Doesn’t depend on temperature

(d) Either increases or decreases

This question was addressed to me in class test.

My question is based upon Voltage-Ampere Characteristics of Diode-1 in portion Diode Circuit of Analog Circuits

Answer 1

The correct answer is (a) Increases

To explain: As temperature increases the conductivity of a semiconductor increases. Reverse saturation current increases as temperature increases.
