Small 31.8 KB PDF bearing the 2SC3294 part number, listed as a schematic but best treated as the component datasheet. The 2SC prefix marks an NPN transistor in the Japanese JIS scheme, and nothing more is stated in the name. Read the maximum ratings and pin diagram inside before replacing the device, check the removed part with a multimeter in diode mode, and make sure any alternative part shares the same lead order and package.
