Datasheet-style PDF for the 2SA1339, indexed in the schematic category at 140 KB. The 2SA prefix denotes a PNP transistor in the JIS scheme, nominally aimed at high-frequency duty. Technicians open this kind of document in any PDF reader to look up terminal order, case style, breakdown voltages, collector current limits and hFE ranges. It is useful when diagnosing a shorted junction on a board or choosing an equivalent replacement, where the ratings of the substitute should meet or exceed the original.
