A simple power diode model with forward and reverse recovery

The basic diode charge-control model used in SPICE is extended by employing the lumped charge concept of J.G. Linvill and J.F. Gibbons (1961) to derive a set of model equations from simplified device physics. Both forward and reverse recovery phenomena are included as well as emitter recombination. The complete model requires only seven relatively simple equations and three additional device parameters beyond the genetic SPICE diode model. A major feature of the model is that the same equations are valid through all regions of operation.<>
