Component documentation for the 2SA1591, an 89.4 KB PDF. Only the part number appears in the name; no revision or manufacturer is given. In Japanese JIS nomenclature, 2SA parts are PNP bipolar transistors aimed at high-frequency circuits. The sheet should list absolute maximum ratings, gain groups and the package outline with lead assignment. Use it to confirm the emitter, base and collector positions when testing with a meter, and to check that any cross-reference part meets or exceeds the original voltage and current ratings.
