Hello, I have the PSpice Version 9.1 Student and these are my only diode parts available:
D1N750, MV2201, D1N4148, MBD101, D1N4002, D1N914
None of them have a forward voltage under 0.7V, but I need one.
What can I do do get one?
I know how to get in the model change settings, but there is VJ stated and as far as I know this the forward voltage. But for example for D1N4002 it states in PSpice VJ=.3905 but in the data sheet it is stated U_F=1.1V. So these are different values.
Can anyone help me?

VJ is a parameter in the diode equation set for DC current. It is not the foward voltage spec. You need a diode with a foward voltage less than 0.7 volts but you don't specify at what current. The MBD101 is your best choice. It is a schottky diode with a max foward voltage speced at 0.6V at If=10ma.
