    Hello all,

    I'm looking for a SPICE model of the 6N139 and despite numerous hours
    searching on the web, I could not find one.
    If someone has such a model at hand, I would very much appreciate if I
    could get a copy of it.

    Thanks in advance

    On the files section of the Yahoo LTSpice group there is a 6N136 model
    if that helps.

    Indeed, I could add a transistor to mimic the darlington stage. But then
    again, which value should I use?

    Can't you measure one out, CTR and so on?
