? ?"Does anyone know where I can get a model for the H11L1 optocoupler?"
There is one in this group, in the Files section.
? ?"There where some messages about this part a few years ago (2011), and it appears that someone came up with a model and posted it, but it is no longer available."
I just downloaded it. ?I don't know anything about the H11L1, but the schematic seems appropriate for an opto-coupler. ?Anode, Cathode, Out, Gnd, and Vcc pins. ?It looks like it is meant to be used as a subcircuit, a lower-level hierarchical page.
The ZIP file that is in the same directory ("AN3006_60Hz_4.zip") has a slightly different version of the same H11L1 schematic, plus an LTspice symbol
?for it ?
that can be used to place it on your schematic for simulation.
