Has anyone had any success with the spice model for the VOM1271T given on the Vishay website?
https://www.vishay.com/docs/80045/spicemodelvom1271.zip
At best, I can get it to work with 100s of mA on the input, mostly it just stops the spice simulation converging.
If the spice model is not trustworthy, please could someone post a circuit of a SSR using the VOM that is known to work.
Thanks

Yes, I did. Searching through again an alternative spice model was offered (Attached). This seems to give more sane outputs than the vishay one.
I use lots of vom1271, and I use the model that you attached in post #3. The model is reasonably accurate.
I normally start the input current at 25mA and then drop it to 15mA (Use two series resistors with one bypassed by a capacitor).
Attached is the symbol that I use.
