FWD Model
The FWD model is a static one only. The static current follows the formula:
–
----------------------------------------------------
VDS – I ⋅ RB_FWD
⎛ M ⋅ VT ⎞
k ⋅ ( TEMP_JNCT + 273K)
I = ISAT, FWD ⋅ ⎜e– 1⎟
VT= -----------------------------------------------------------------
⎝ ⎠
q
k = Boltzmann constant (1.381E-23) q =
Elementary charge (1.602E-19)
