102N21A DE-SERIES SPICE Model
(Preliminary)
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 ca-
pacitance, 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.
