I have a diode that I want to model, it's a 85HF20.
<http://www.vishay.com/docs/93529/85hf.pdf>
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)
Thanks
