Hello forum,

I'm trying to model this shotkky diode: http://www.alldatasheet.com/datasheet-pdf/pdf/192132/MICROSEMI/APT60S20B.html .

Unfortunately, the parameters needed by spice (which are outlined here: http://www.acsu.buffalo.edu/~wie/applet/spice_pndiode/spice_diode_table.html) are not listed in the datasheet the manufacturer provides.

This is my first time modelling a whole circuit(an already manufactured circuit) in LT Spice IV, so I ask you what the next step could be?

Thanks a bunch,
MrBuggy

 

I see several possible approaches:

1. Ask the manufacturer if they have a SPICE model, or check their website.
2. Learn enough about device modeling to write one.
3. Collect enough test equipment to measure characteristics not in the datasheet.
4. Check the Yahoo group to see if someone else has already solved the problem.
