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.

तापमान में वृद्धि के साथ डायोड का विपरित संतृप्त धारा बढ़ती है।

गणितीय रूप से यदि विपरित संतृप्त धारा I01 तापमान Tपर और I02 तापमान T2 पर है तो:

\(\)I02 = I01 2(T2-T1)/10

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