Short 30.1 KB PDF for the 2SC5778 transistor, placed in the schematic category. Japanese JIS codes beginning with 2SC denote NPN bipolar devices, so the contents are most likely a brief datasheet with ratings and a pin diagram. No maker, package or revision appears in the name. When a transistor in a power or signal stage reads shorted, this sheet helps confirm orientation and limits before ordering a replacement. Always compare the package drawing with the actual part on the PCB.
