A 92.7 KB PDF catalogued under schematics but titled only 2SJ228, a JIS-style designation used for P-channel FETs. In practice it should be a single-part datasheet covering pin assignment, absolute maximum ratings and characteristic curves. Repair work typically uses it to verify gate, drain and source orientation and to pick a replacement with equal or higher voltage, current and dissipation ratings. The file name does not identify the manufacturer, so confirm the body marking and package on the failed device first.
