Can't we say that the current is, generally, equal to ID = Im - Is and in case of reverse bias, being Im near equal to zero, then ID = -Is giving us the current direction too?
Reverse saturated current is temperature dependent. So no matter what bias you apply a feeble amount of current (opposite direction to FB current, & same direction as RB current) will be there.
Hello sir, small doubt. If diode is open circuit when reverse bias voltage is applied to it. Then what exactly is reverse saturation current because when it is open circuit the current should not flow right.
That is for the ideal case.....in ideal case no current should flow......but irl a small amount of current flows in reverse bias condition before reaching the breakdown point
doesn't the expression for Vt here , contradicts the expression for Vt in lect 10 (barrier potential) there it was Vt= (KT)/q and here it is rep as Vt=(T) / Kn, how?
