Does rev. saturation current also flow during forward biasing of PN diode?Is this drift or diffusion current?

Question

I think it is...But regarding type I am confused...

Answer 1

i think..

REVERSE SATURATION CURRENT flows only during reverse bias  n it is due to minority carriers in P and N region...it is more at break down voltage...

DIFFUSION current flows at time of formation of pn junction...

refer "semiconductor devices" byFLOYD....

drift is different from reverse saturation current......

Answer 2

Dear pa,

Thank you, am also fine like you, then dear i thought it is not like that please for me do not confuse.

Answer 3

i think so its drift

Answer 4

yes,a very small amount of reverse saturation current flows. It is a diffusion current  not a drift current. It is because of charge gadient by immobile ions.
