An increase in junction temperature of a semiconductor diode

A)
causes a large increase in reverse saturation current
B)
does not affect reverse saturation current
C)
causes a small increase in reverse saturation current
D)
may cause an increase or decrease in reverse saturation current depending on rating of diode

Correct Answer : Option (A) :   causes a large increase in reverse saturation current

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