Compact 30.7 KB PDF covering the 2SJ628, catalogued as a schematic but most likely a single-device datasheet given the part-number name. In JIS semiconductor coding, 2SJ stands for a P-channel FET, a type often found in power switching and load-switch circuits. Open it in any PDF reader to check pin assignment, drain-source voltage rating, on-resistance and package outline. Since the file name carries no maker or revision, verify the body marking on the board before relying on these figures for a swap.
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.
