PDF document for the 2SJ346, filed in the index as a schematic but named after a discrete semiconductor part. Under the Japanese JIS numbering system, the 2SJ prefix marks a P-channel field-effect transistor, so the content is most likely a datasheet with pinout, package outline and electrical ratings. At 307 KB it should open in any PDF reader. Use it to confirm gate, drain and source pins before testing a suspected shorted MOSFET, and compare voltage and current ratings before fitting a substitute.
