Anyone know what this thing is? The bin I pulled it from said "Xsistor" but I can't find much info on it.

Thanks,
Marcus

    Looks like an RF transistor:

    We use something like it on some older equipment. Made by Motorola before they became On-Semiconductor.

    They look like dual-gate MOSFETs that might be used in RF circuits.

    Edit: you were a little quicker than I was. I wasn't aware they used that package for bipolars, but obviously they do. Digikey calls it a Micro-X package.

    Yep, that's it. Thanks. I've never seen this package before.

    It's a common package for high frequency/microwave RF. Not used for much else.
