The reverse current of a diode is very temperature sensitive.

The current doubles for every 10°C rise in temperature.

The reverse saturation current of the diode increases with an increase in the temperature.

Mathematically, if the reverse saturation current is I01 at a temperature T1 and I02 at temperature T2 then:

\(\)I02 = I01 2(T2-T1)/10

Nature of the reverse current of a silicon diode highly temperature-sensitive.
