Hi, anyone have a link to a workable spice model for 6N139 optocoupler ?
A basic coupler's LED drives a photo-tranny: 6N139 has a fast photo-diode detector and split-darlington amp with base access for sensitivity / bandwidth trade-off...
Sadly, the usual libraries seem to lack any coupler with diode detectors, never mind a 'similar' split darlington.
I've googled extensively, searched manufacturers' sites and documents, drawn blank. Unfortunately, I do not have access to the 'graph-to-model' tools found in some spice versions.
( This is not a college / assignment query. )
