A 139 KB PDF titled 2SJ507, placed in the schematic section of the index. The 2SJ prefix belongs to the JIS semiconductor scheme and denotes a P-channel FET, which suggests a single-part datasheet rather than a circuit for a specific device. Technicians use such sheets to confirm pinout and package, compare RDS(on), threshold and breakdown voltage with candidate substitutes, and interpret meter readings when testing a suspect transistor. Nothing about brand or revision is stated, so verify the physical marking.
