RF Power MOSFET
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.
