Where to use 2SC1815
The C1815 is a general purpose NPN transistor that is commonly used in Amplifier applications. There are four variants, the 2SC1815O will have a gain value of 70 to 140 and the 2SC1815Y will have 1020 to 240, the 2SC1815GR will have 200 to 400 and the 2SC1815L will have a gain range from 350 to 700.

This NPN transistor also has its counterpart PNP transistor the 2SC1015, which makes it ideal for Push-pull and class B amplifier designs. Apart from this the transistor can also be used for switching low power devices.
