Named after the 2SA1527 transistor, this 30.7 KB PDF appears in the schematic category though its content should be the datasheet for the part. JIS registration uses the 2SA prefix for PNP transistors aimed at high-frequency circuits. For repair, the useful parts are the package drawing, pin identification, maximum collector voltage and current and the hFE table, which together decide whether a substitute is safe. Verify the device marking on the PCB before ordering or fitting a part.
