What happens to cut-in voltage when the temperature increases?

Electronics and Communication Engineering (ECE) : Analog Electronics - Quiz(MCQ)

Cut-in voltage decreases

Cut-in voltage increases

Cut-in voltage either increases or decreases

Cut-in voltage doesnâ€™t depend on temperature

Correct Answer : Option (A) : Cut-in voltage decreases

Explanation : As temperature increases the conductivity of a semiconductor increases. The diode conducts smaller voltage at larger temperature. Therefore, cut-in voltage decreases.
