A 70.0 KB PDF categorised as a schematic but named solely after the part 1SS272, with no device, board number or revision. The 1SS prefix is the JIS designation for small-signal diodes, a numbering largely used by Toshiba, so expect a component datasheet. Technicians open it in any PDF reader to confirm polarity, internal arrangement, reverse voltage and current ratings, and the package marking. Checking those against the diode on the PCB is essential before choosing a compatible replacement part.
