Reference PDF for the 2SA1127 transistor, 41 KB, filed in the schematic category, with an _E suffix in the name whose meaning is not stated. The 2SA prefix follows the JIS convention for PNP bipolar transistors. Expect absolute maximum ratings, gain figures and an outline drawing on a few pages. It is useful when a part has failed short in an audio or power stage and you need to verify the pin order and find a replacement with equal or better ratings. Any PDF reader opens it.
