C1815 NPN Audio Amplifier Transistor

are semiconductor devices which is used to amplify small signals coming from a sensor or a circuit and other systems to be recorded and registered by the controller you are using or any data logger to register your signals which generally are too small to be read by it. It is an active component and it can also be used in switching circuits to turn on or off the intended devices. It has 3 terminals namely Base(B), Collector(C), Emitter(E) for connections with other components in the circuit. Some transistors also contain fourth terminal named Substrate(S). The C1815 is a high voltage and high current NPN transistor. A transistor can normally be used as a switch or amplifier, but this transistor is commonly is used only for audio frequency amplifier application since it has a very high dc current gain value of 120-700. It can switch on or off the loads with voltages upto 50V. When transistor is fully biased which you can do with base emitter voltage of about 1.1V, it can carry a collector current upto 150mA. It can be used in Darlington Pair, audio Amplification, driver stage amplification etc.
