Datasheet in PDF form for the FDMC7692 part, a power MOSFET designation used in Fairchild (now onsemi) numbering, with the trailing -d suffix most likely marking a document revision. At 275 KB it should hold the pinout, absolute maximum ratings, on-resistance figures and package drawing. Technicians use such a sheet to confirm gate, drain and source pads before measuring a suspected short on a power rail, and to pick a replacement with equal or better voltage and current ratings. Check the package marking on the board before swapping.
