Where we can Use it  & How to Use?

2SA1015 transistor is mainly used for audio amplifier applications.this transistor can also be used for the switching purpose, When used as an audio amplification, can be drive in active region. It is divided into four categories other according to the DC current gain, O(140), Y(240), G(400), and L(700)  hfe DC current gain respectively.2SA1015 is used in the below circuit of LED flasher, capacitor C1 and R1 is used as audio frequency generator to Q1 &Q2 transistor which is used as switch. And, Q2 is also used for growing the current. From capacitor C1 through R2 and LED, Q1 will work until the voltage drop increases across C1. Consequently, Q2 starts of held, and a current flows through LED and it remain ON.
