C1815 NPN Transistor: Pinout, Equivalents, and Uses

Also known as 2SC1815, the C1815 is a bipolar junction NPN transistor widely used in commercial and educational projects. It is designed for audio frequency amplification and high-frequency oscillator(OSC). The collector-base voltage of the C1815 is 50V, hence it can be easily used in circuits using under 50V DC. The collector current of the C1815 is 150mA, therefore it can drive any load under 150mA. The collector power dissipation and DC current gain of the C1815 are quite good, so it is a perfect choice for audio and electronic signal amplification purposes.

The C1815 transistor has a current gain anywhere between 70 and 700. The gain of the C1815O will be in the range from 70 to 140, C1815Y ranges from 120 to 240, C1815GR ranges from 200 to 400, C1815BL ranges from 350 to 700.
