PDF of 87.3 KB named after the 2SA1347 transistor and nothing else, so it is best regarded as a datasheet despite the schematic label. JIS numbering uses the 2SA prefix for high-frequency PNP transistors. A repair technician would turn to it for pin layout, package dimensions, breakdown voltages and hFE classes when testing a suspect device or selecting a replacement. Look for the shortened body marking A1347 on the component and confirm it matches before substituting.
