The 2SC3606 is the only detail given by this 464 KB PDF, catalogued as a schematic yet functionally a part datasheet. JIS designations starting with 2SC refer to NPN transistors for high-frequency service. When a transistor on a board tests shorted or open, a sheet like this tells the technician which terminal is which, what voltage and current it tolerates and what gain to expect, so a correct substitute can be chosen. Open it with any PDF reader and confirm the case style before ordering a replacement.
