Abstract :
A physics-based model for PiN power diodes is developed and implemented as a SPICE subcircuit. The starting point of the model is an equivalent circuit representation of the base region, obtained by solving the ambipolar diffusion equation with the finite difference method. The model is validated against experimental characterization carried out on commercial fast recovery power diodes. Comparisons between the results of the SPICE model with experimental results and SILVACO mixed-mode simulations are presented
