Brief 29.5 KB PDF identified as 2sj163. In the Japanese JIS scheme the 2SJ prefix marks a P-channel field-effect transistor, so the content is probably a short datasheet despite the schematic label. Look for pinout, polarity and maximum ratings. Because P-channel parts conduct with opposite gate polarity to N-channel ones, check this carefully when testing or substituting, and confirm the package and lead order on the board match the document.
