Compact 79.7 KB PDF for the 2SJ413, indexed under schematics but by its number a single-component datasheet. The JIS prefix 2SJ identifies a P-channel FET, a device commonly found switching supply rails or driving loads in power and audio circuits. The name gives no manufacturer, package or version. Read it in any PDF viewer to get the pinout and limits, test the part with a meter in diode mode, and check the case marking before trusting the document for a specific board.
