A 41.1 KB PDF named for the 2SC3312 part, listed as a schematic yet in practice a component datasheet. The 2SC prefix under the Japanese JIS standard denotes an NPN transistor, and the _E ending possibly marks an English-language release. Before replacing a suspect part, compare the body marking and package with the drawing inside, read the absolute maximum ratings, and test the old device with a meter in diode mode to confirm it is really faulty.
