Hi Dr_PC_Repair,
From the datasheet of the Rohm EMD2 / UMD2N / IMD2A, the part marking for all three variants (different package sizes) is “D2”, which, along with the part numbering in the schematic, pretty much guarantees this is the right part.
Presumably, it is the SOT-363, based on the part number in the schematic, but you can verify by studying the package dimensions on pages 7-9 of the datasheet.
