  1. Can it be a TVS diode ? A TVS diode is placed in parallel with the positive and negative.
    Below the specific voltage, they are "open", and once they reach there treshold voltage, they begin to conduct to clamp down the voltage.
    You can leave temporary the diode out, and supply a low voltage like 3a5V (and limit the current at your lab supply) , at the pads where the diode was soldered, and then look how much amp the board draws. If the diode was short, the voltage over the diode can't be very high, so i don't think that there is further damage to the board.
