C1815 Transistor Pinout, Equivalent, Uses, Features
C1815 is a bipolar junction NPN transistor widely used in commercial and educational projects. It is used for audio amplification and high-frequency oscillator(OSC). It can be easily used in circuits using below 50V DC because the collector-base voltage of this transistor is 50V. The collector current of the transistor is 150mA which is why it can drive a load below 150mA. It is ideal to use in audio amplification because collector power dissipation and DC current gain value are very good. Moreover, it can also be used as a switch to drive loads under 150mA.
