I have a diode that I want to model, it's a 85HF20.
This is one of those standard stud mounted rectifiers.
This is the model that I created for it: .model 85HF20 D(BV=200 Ibv=.009 Is=1e-3 Cjo=2300p M=0.43 Rs=.00169 Tt=100u Eg=1.11 Vj=1.2 Fc=0.5 N=1.1 )
Cjo was taken for a similar sized schottky . I don't have experience with these larger diodes so the model is almost default values. I don't need the Temperature parameters. Most of the reference books , I have, don't deal with the larger diodes. Is the Is parameter correct for this model? Any pointers?
I basically need to know if this slow diode will clamp a forward voltage from a inductor. the model above does work. But its no good if its wrong. ( I had another model that didn't work well)
