The 2SA1865 PNP transistor is described in this 55.3 KB PDF, identified solely by its JIS part number. A 2SA code always denotes a PNP bipolar device, so the content is component specifications, not the device schematic its catalogue type suggests. Technicians open such sheets in any PDF reader to verify pinout, case dimensions and electrical ratings before swapping a damaged part. When the exact transistor is unobtainable, choose an equivalent whose voltage, current, power and gain at least match, with the same pin order.
