The 2SA1362 gets this 201 KB PDF, which carries only the part number and is therefore most likely the manufacturer datasheet rather than a board schematic. In the JIS scheme a 2SA prefix identifies a high-frequency PNP transistor. Repair technicians use such sheets to confirm pin functions, case type and electrical limits, to compare hFE classes and to find a complementary NPN partner. Bear in mind that the printed body code usually omits 2S, appearing as A1362 on the component.
