Is there any Ideal diode component in pspice ?
DBREAK from breakout.lib is something you may want to try. This diode would have zero reverse recovery time, nominal junction capacitance and resistance. You can edit the Cjo and Rs model parameter to bring these value to zero. I guess this is what you may mean by saying ideal. However please not having RS=0 can pose convergence issue in some circuit situation, specially switching circuits.
