Question

State True or False:

Saturation current depends on temperature.

• A. True
• B. False

Answer 1

The correct option is A True

Reverse saturation current in p-n junction diode will be just double in magnitude for every ${10}^{o}C$ rise in temperature.

This is true because of the more energy gained by the minority carriers from what is called thermal voltage ($Vt$) by the heat energy dissipated at the junction .

Higher heat=>> High voltage =>> More minority carriers =>> Higher reverse saturation current.
