Component documentation for the 2SA1314 in PDF format, 162 KB. The type field says schematic, but the name consists only of the part code, which normally means a datasheet. The 2SA prefix places it in the JIS family of PNP bipolar transistors. When a device of this type fails, the sheet helps a technician identify leads correctly, compare voltage and power limits, and pick a replacement with a suitable gain rank. No maker or revision is given, so verify the package against the drawing.
