Component documentation for the 2SJ343, supplied as a 337 KB PDF. Apart from the part number, the name gives no model, board or revision. JIS numbering assigns 2SJ to P-channel FETs, so the sheet should list absolute maximum ratings, characteristic curves and the mechanical package outline. It is handy when a failed transistor has to be identified and replaced. Always match the package and pin order, and remember that a P-channel device cannot simply be swapped for an N-channel one.
