A 41.6 KB PDF for the 2SC3114, an NPN bipolar transistor under the JIS 2SC designation. Although catalogued as a schematic, the bare part number suggests a short component data sheet. The case typically carries the marking C3114. No package, hFE grade or manufacturer is named. Read the pinout before taking diode-mode measurements, check collector-emitter voltage and current limits against the rail involved, and make sure a substitute matches both electrically and in footprint before soldering it in.
