PDF covering the 2SC5301 transistor. Under the JIS designation system the 2SC prefix marks an NPN bipolar device. The name carries nothing beyond the part number, so expect a component datasheet rather than a board schematic despite the catalogue category. The 96.2 KB file will typically list collector-emitter voltage, collector current, gain and package drawing. Compare these figures and the pin layout carefully when choosing a replacement, and open the file in any PDF viewer.
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.
