Reference document in PDF form for the 2SC5361, a part number following the Japanese JIS scheme where the 2SC prefix denotes an NPN bipolar transistor. Although indexed as a schematic, a file named only by a component number is most likely a datasheet. At 207 KB it should hold pinout, absolute maximum ratings and electrical characteristics. Technicians use such a sheet to confirm the pin order and voltage and current limits before fitting a substitute, so check that the package matches the original.
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.
