A 29.4 KB PDF for the 2SJ569LS, catalogued as a schematic though it is named in the style of a component datasheet. The 2SJ prefix is the Japanese JIS designation for P-channel field-effect transistors, and LS marks a variant that the name does not define. Use the document to check pinout, voltage and current limits and the package outline before substituting a part. Make sure the full part code, including the suffix, matches the device on the board, as no maker is stated.
