Datasheet PDF for the 2SA928A from UTC, the Unisonic Technologies brand named in the file, 23.1 KB, filed in the schematic category. Under JIS-style numbering 2SA marks a PNP bipolar transistor, and the A suffix denotes a variant of the 2SA928. UTC produces many second-source versions of Japanese transistors, so pinout and package may differ from the original maker's version; verify the layout against your board before fitting. Ratings and hFE grades help confirm suitability.
