The 2Sa1015 is a PNP transistor that is mainly used for general-purpose amplification. This transistor consists of three terminals: emitter, base, and collector. The n layer represents the base side and the P layers represent the emitter and collector. In the market 2sa1015-y, 2sa1015 and a1015 are available.
The pinout of this transistor is given below in the diagram and all configuration is also given below in the table.
| Pin No. | Pin Name | Description |
| 1. | Emitter | current drain in through Emitter |
| 2. | Collector | current flow out through the collector |
| 3. | Base | control the current between Emitter & collector |

2SA1015 transistor is mainly used for audio amplifier applications. This transistor can also be used for switching purposes, When used as an audio amplification, can be driven in the active regions. 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 a switch. And, Q2 is also used for growing current. From capacitors 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 the LED and it remains ON.
