PDF for the 2SA2066 transistor at about 201 KB, catalogued with schematics but representing a component datasheet. By the Japanese JIS scheme, the 2SA designation means a PNP transistor in the high-frequency class. The document should list terminal assignment, case style, maximum voltage, current and power limits and characteristic curves. Use it during board repair to confirm orientation, check measured values against expected behaviour, and evaluate substitutes; always verify the marking and package on the actual part first.
