Part documentation for the 2SJ103, a 282 KB PDF in the schematic category. The JIS designation 2SJ identifies a P-channel FET, so the file is expected to be its datasheet rather than a device circuit diagram. The name gives no manufacturer or package. Use it for pinout, polarity and maximum ratings when diagnosing the stage it sits in, and compare package and lead order with the board before installing any equivalent.
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.
