501N21A DE-SERIES SPICE Model
The DE-SERIES SPICE Model is illustrated in Figure 7. The model is an expansion of the
SPICE level 3 MOSFET model. It includes the stray inductive terms L
G
, L
S
and L
D
. Rd is
the R
DS(ON)
of the device, Rds is the resistive leakage term. The output capacitance, C
OSS
,
and reverse transfer capacitance, C
RSS
are modeled with reversed biased diodes. This
provides a varactor type response necessary for a high power device model. The turn on
delay and the turn off delay are adjusted via Ron and Roff.
