    I've found the ideal, but still unobtainium phototransistor, Vishay's
    VEMT4700F.
    Features surface mount, wide angle (120° half sensitivity), IR filter,
    and base access. All this is required.

    Unfortunately unavailable for now.

    Any other reference with all those features? I can trade surface mount
    for availability for prototyping :)

    Thanks, will go with that one. Don't know why I did focus only on 2
    junctions...

    Antinomium, nice word, I had to Google it:

    from Secret Symbols of the Rosicrucians (Second Book):
    But when Thomas Aquinas calleth it Antinomium, he doth so because of its
    black ...
    Antinomium is opposed to all metals and burneth them all except the
    gold. ...

    Also used in vitamin supplement descriptions, but not in dictionaries
    yet. Looks like you are the first to use it with the meaning of "name of
    something impossible" or perhaps "self contradicting nomenclature" - but
    I think it might catch on. Clearly a far better word than the plebeian
    and vaguely insulting "oxymoron", the use of which should be deprecated
    now that we have a better word :). I am emailing it to a group of
    friends as the word of the day, I think they will like it better than the
    last one I sent, which was reocentric. (They are a psychocentric bunch.)

    Piers Anthony (with fan club as needed) can probably go a few rounds with
    Spider.
