Reference sheet for the 2SA1689 in PDF format, 74 KB, indexed as a schematic despite a file name that indicates a standard transistor datasheet. Following JIS rules, 2SA identifies PNP transistors classed for high frequency. No revision, maker or package details appear in the name itself. Technicians rely on such a document to confirm the terminal order, read voltage, current and dissipation limits, and compare gain classes when choosing an equivalent part for a repair.
