C1815 Transistor Explained / Description:

C1815 is a widely used transistor, it is used in commercial and educational projects. It is designed for audio frequency amplification and high frequency OSC. The collector-base voltage of the transistor is 50V therefore it can be easily used in circuits using below 50V DC. The collector current of the transistor is 150mA therefore it can drive any load below the 150mA limit. The collector power dissipation and DC current gain values of the transistor is quite good due to which it is ideal to use in audio amplification and electronic signal amplification purposes. Moreover it can also be used as a switch to drive loads under 150mA.

 

Where We Can Use it & How to Use:

C1815 transistor can be used in audio amplification stages, small audio amplifier (if used to drive small speaker), preamplifier and also in preamplifier stages. It can also be used switch in electronic circuits to drive loads under 150mA for example to drive relays, other high power transistors, low power LEDs and other parts of an electronic circuit etc. It can also be used to make darlington pair.

 

Applications:

Sensor Circuits

Audio Preamplifiers

Audio Amplifier Stages

Switching Loads under 150mA

RF Circuits

 

How to Safely Long Run in a Circuit:

To get long term performance from this transistor it is recommended to not drive load above 150mA with this transistor, always operate it below the max collector-emitter voltage, always use a suitable base resistor to provide require base current to the transistor, do not store or operate the transistor below -55 centigrade and above +150 centigrade.
