Named after the JIS part number 2SJ267, this 91.8 KB PDF most likely documents a P-channel field-effect transistor, since the 2SJ prefix denotes that device class. The catalogue files it under schematics, but the name gives no device or board, so treat it as a datasheet. It helps a repairer confirm gate, drain and source pins, limits on voltage and current, and package style when tracing a fault in a switching or amplifier stage. Read it in any PDF viewer and verify polarity before choosing a replacement.
