PDF reference for the 2SA1699, a transistor identified by its JIS registration code; the index files it as a schematic, but documents named this way are generally manufacturer datasheets. The 2SA prefix designates a PNP high-frequency transistor. The name carries no revision or variant information. Technicians use such a sheet to read package outline, pin numbering and limiting values, and to compare hFE ranks when matching a substitute, viewing it with any standard PDF reader.
