Datasheet in PDF format for the 2SA1579 transistor, 36.6 KB. Only the part number is given in the name. Japanese JIS codes beginning with 2SA designate PNP bipolar transistors suited to high-frequency work. The document likely lists maximum voltage and current limits, hFE classes and the lead layout. Repair use includes identifying pins for diode-mode testing and selecting an equivalent when the original is unavailable. Pay attention to any suffix letter on the fitted part, which commonly encodes the gain grade.
