Indexed as a schematic, this 411 KB PDF is named for the 2SJ516, and in Japanese semiconductor numbering 2SJ denotes a P-channel field-effect transistor. Expect a datasheet with ratings tables, characteristic graphs and an outline drawing instead of a device circuit. It helps when evaluating a failed transistor, confirming which leg is gate or drain, and comparing on-resistance and capacitance with possible equivalents. The file name carries no brand or package detail, so confirm those against the physical part before ordering.
