Very small PDF, only 16.5 KB, named 2pg352 and catalogued under schematics. The name is terse and gives no device, brand or board number, so it most likely holds a one or two page component sheet rather than a complete circuit diagram; it sits alongside similarly named files 2pg351, 2pg302 and 2pg301. Use it to look up pin assignment and ratings of the part in question before replacement. Open it in any PDF viewer and verify that the part marking on the PCB really corresponds to this designation.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
