Reference PDF for the 2SA1469, 101 KB, filed under schematics. Japanese JIS numbering uses 2SA for PNP transistors oriented toward high-frequency applications, which distinguishes them from the low-frequency 2SB series. Expect pin assignment, maximum ratings, transition frequency and characteristic graphs. Use the document when verifying a part from its marking, testing junctions in diode mode, or choosing an equivalent; for RF or fast-switching positions, frequency response matters as much as voltage and current.
