501N21A DE-SERIES SPICE Model
(Preliminary)
The DE-SERIES SPICE Model is illustrated in Figure 1. The model is an expan-
sion 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 mod-
eled with reversed biased diodes. This provides a varactor type response neces-
sary for a high power device model. The turn on delay and the turn off delay are
adjusted via Ron and Roff.
