In regard to IS the saturation current of a pn diode:

1. I_S decreases with increasing temperature
2. I_S increases with increasing temperature
3. I_S is due to thermally generated minority carriers
4. I_S is mainly a diffusion current at the junction

Correct Option: C

Saturation current, I_s is due to thermally generated minority carriers
