Identified only as 115cnq015a, this 193 KB PDF sits in the schematic category with no board number, revision or product mentioned. The code resembles a dual Schottky rectifier part number with a voltage suffix and an extra letter variant, so expect a component sheet with ratings and package drawing. Open it in any PDF viewer. When replacing a part, compare the full marking including the trailing letter, since such suffixes can indicate a different package or pinout from the base part.
