Filed as a schematic, this 372 KB PDF named 2SJ465 most likely holds the full datasheet for a P-channel field-effect transistor, since that is what the 2SJ prefix means in the Japanese JIS naming system. Expect ratings tables, typical characteristic graphs and a dimensioned package drawing. Repair work uses this to confirm pinout, check safe operating limits, and find an equivalent with comparable voltage, current and RDS(on). Nothing about manufacturer or application is given, so compare the physical marking first.
