Interesting First Cut at Spice Modeling of TLP191B...

Tanh very useful. However... I haven't run your model, but it looks like
you have omitted input diode modelling. The clue is that I don't see any
Diode model with N !=1
I did this model for a H11FXM opto a while back. Matches DC curves very
well.
.SUBCKT h11fxm_XN 1 2 3 4

B1 3 4 i=0.04*tanh(20*V(3,4))*I(V1)
D1 1 5 DMod
V1 5 2 DC 0
c1 3 4 10p
c2 1 3 0.2p
c3 2 4 0.2p
.model DMod D(is=1p Rs=3 CJO=50p Tt=10n Bv=50 Ibv=0 N=2.15)

Thanks, Kevin, I'll try that out.
