What happens to cut-in voltage when the temperature increases?(a) Cut-in voltage increases(b) Cut-in voltage decreases(c) Cut-in voltage either increases or decreases(d) Cut-in voltage doesn’t depend on temperatureI got this question during an online interview.My question is from Voltage-Ampere Characteristics of Diode-1 in division Diode Circuit of Analog Circuits

Answer»

Correct choice is (B) Cut-in voltage decreases

Easiest explanation: As TEMPERATURE increases the conductivity of a semiconductor increases. The DIODE CONDUCTS smaller voltage at larger temperature. THEREFORE, cut-in voltage decreases.
