The greater focus on material parameters like mobility and gate oxide thickness is important because there is no single model for SiC MOSFETs. Zero-bias capacitances: the base-emitter and base-collector capacitances need to be defined, as well as the forward-bias depletion capacitor coefficient. These models might define the impedance (e.g., for capacitors and inductors) as a function of frequency, which allows for AC simulations. The spice parameters are used to create a lumped-element equivalent circuit model of a half-wave rectifier that is compared to a full device level simulation. This is important if an AC signal is applied to the base/gate, as a large amplitude will cause the collector/source current to saturate. Change Location. English. SPICE Models for Diodes.
