    Probably is a transistor...
    Test it with the tester in diode mode to find base-collector-emitter.

    I'm fairly sure it's a diode. There's another on the board and it checks to
    be a diode. The board layout has only 2 connected pads. If it were larger,
    I'd remove the other from the board and apply voltage to it to see if it had
    a breakdown voltage near 6.8v but the physical size would make it difficult.

    If it is a diode, it is most likely as you suspect a 6.8Vz. Looking at the
    SOD-80 diode markings, to looks to be a corrupt form of mark (6Y8 but 6.8Y)
    for a 6.8Vz.

    To confuse matters there is also a transistor 68Y but without the decimal
    point <grin> and it's in the SOT-89 package. I see a load of diodes in this
    same package, they use ether two pins only or have the opposite two pins
    tied together.
