Documentation for the 2SJ378 P-channel FET in a 418 KB PDF, listed as a schematic though really a datasheet. The 2SJ prefix follows the Japanese JIS naming system, where J signals a P-channel field-effect transistor. No maker, case or revision is stated in the name. Use it to identify gate, drain and source, to check maximum ratings and switching characteristics, and to compare candidate substitutes, making sure the package and pin order match the footprint on the board.
