Identify Transistor (?)

Discussion in 'Electronic Components' started by Alan 'A.J.' Franzman, Feb 2, 2007.

  1. I'm trying to identify what looks like a transistor in a TO-92 package,
    painted silver on the flat side and apparently marked:
    0T380
    W 2n

    This doesn't seem to fit the JEDEC, JIS or Pro-Electron formats; am I out of
    luck?

    It looks more like the format used for SMT devices actually.

    I suspect you'll need to make an informed 'guess' from circuit function what
    it's likely to be.

    FWIW, www.usbid.com suggests that it is a Philips part.

    Philips parts sometimes have that silver on them but invariably IME have ph too.

    Philips OT380 is SOT54 SMD, not TO92 through-hole.

    OY! SOT-54 IS a through-hole part.

    Sorry for the miss-info.

  7. Yes, and according to http://www.nxp.com/package/SOT54.html, it's the same as
    TO-92. Why do we need a new name for it? I'll stick with the old one, thank
    you very much!

    So, what /IS/ a Philips Oscar Tango Three Eight Zero anyway? I just noticed
    that the board legend for it begins with "D" as in "Diode" - is it perhaps a
    dual diode?

    I find some online suppliers claiming to stock it, but no info.

    I think you're back to the informed guess scenario, if Philips/NXP
    won't own up to at least a product listing.

    It was considered 'standard' enough to process paper for matte-tin
    pbf-free packages. As you say, brokers seem confident in being able to
    supply it.

    If this is a repair job, why not go through distribution?

    Philips made RF strip-line modules at one time, with the OM prefix.

    O is a designator generally avoided, to prevent confusion with zero.
