Q1: An increase in junction temperature of a semiconductor diode

A causes a small increase in reverse saturation current

B causes a large increase in reverse saturation current

C does not affect reverse saturation current

D may cause an increase or decrease in reverse saturation current depending on rating of diode

ANS:B - causes a large increase in reverse saturation current

Reverse saturation current doubles for every 10°C rise in junction temperature.
