The model is an expansion of the SPICE level 3 MOSFET model. It includes the stray inductive terms LG, LS and LD. Rd is the RDS(ON) of the device, Rds is the resistive leakage term. The output capacitance, COSS, and reverse transfer capacitance, CRSS 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.
