Where to Use A1015 PNP Transistors?

The main use of 2SA1015 is for audio frequency amplifier applications. It can also be used for the switching purpose just like other PNP transistors. When use as an Audio frequency general purpose amplifier, can be operated in the active region. This transistor is further divided into four groups according to the D

Amplification factor usually determined in term of power, for calculating the current gain we use the formula:

G

ain (hfe) = I

Where, I

C

is the collector current and I

B

is the base current of the circuit. How to Use A1015 Transistor? In the below circuit of

L

E

D flasher using 2SA1015, capacitor

C

1 and R1 used as frequency generator to Q1 transistor which is used as switch for Q

2.

And, Q2 is used for increasing the current. From capacitor

C

1 through R2 and

L

E

D, Q1 will work until the voltage drop increases across

C

1.

As a result, Q2 starts conducting, and a current flows through

L

E

D and it turns

O

N. While

C

1 discharged through R1 to a period of time, when

C

1 discharge out there would be no pressure to bias the base terminal of the Q

1.

Hence, the Q1 stop working which also stop Q2 to work. Therefore,

L

E

D turn

O

FF and

C

1 will start again and this cycle continues. And, the turning

O

N and

O

FF of

L

E

D seems as a flasher.

Applications

1. Switching
2. Driver stage amplifier action
3. AF amplifier

C

an be used Darlington pair
4. Used in making led flasher
