Saturation current is a term used in relation to semiconductor diodes. It is more fully named reverse saturation current and is "part of the reverse current in a diode caused by diffusion of minority carriers from the neutral regions to the depletion region.
IS, the reverse bias saturation current for an ideal p-n diode is given by,
where
<dl> <dd>IS is the reverse bias saturation current,</dd> <dd>e is elementary charge</dd> <dd>A is the cross-sectional area</dd> <dd>Dp,n are the diffusion coefficients of holes and electrons, respectively,</dd> <dd>ND,A are the donor and acceptor concentrations at the n side and p side, respectively,</dd> <dd>ni is the intrinsic carrier concentration in the semiconductor material,</dd> <dd>τp,n are the carrier lifetimes of holes and electrons, respectively.</dd> </dl>4Thank You
