Reverse Saturation Current Density in pn junction diode
This CalcTown calculator calculates the reverse current saturation density in a pn junction diode, which is mainly due to the corresponding minority charge carriers in the p side and the n side.
where Lp is related to Dp and the corresponding relaxation time constant
*Implicit are the assumptions that:
1. The contribution of intrinsic charge carriers in total charge concentration is negligible.
2. Wn>>Lp and Wp>>Ln
Intrinsic carrier concentration
