    Hi, I'm trying to find out the current rating of this component.

    Apparently it's in series with a 5V power output in a TV set. (PSU board)

    It looks like a 8 pin TSSOP from Fairchild.

    I would guess a high side switch p-channel MOSFET, but can't seem to find the right one.

    Thanks

    TI OPA552 high voltage op amp?

    No the connections to the pins wouldn't make sense.

    The "Q" part number indicates a FET, which makes sense from the pinout.

    Logo seems to be Fairchild?

    Yes I thought so to. But which one ? :)

    Probably a dual MOSFET - isn't that the Fairchild logo on it?

    No the pinout is simple with ganged pins, it would be a single mosfet.

    If the OP really wants more info we need to see larger picture of the PCB both sides to see how it all connects. :)

    The one I linked to is a single mosfet. No?

    Some are single, some are duals - the duals subdivide into both the same polarity and complementary pairs.
