Replacement and Equivalent

2N2907, 2N3906, A733, 2SA1266 (The pin configuration of these transistors may different from A1015, therefore it is recommended to first check pin configuration of the transistor you are replacing with A1015 in a circuit.)


A1015 Transistor Explained / Description

A1015 is a low cost good quality PNP transistor that is mainly designed to use as an audio amplifier or in audio amplification stages. The max collector to emitter voltage of the transistor is 50V therefore it can easily be used in circuits operating under 50V. For good performance it is recommended to use the transistor in circuits operating under 40V DC. The max collector dissipation of the transistor is 400mW and max DC current gain is 400 which makes this transistor a better device for small audio amplification. Moreover it can also be used as a switch and it can handle 150mA of load.



Where We Can Use it & How to Use

As mentioned above A1015 mainly manufactured for audio amplification purposes so it can be used as a small audio amplifier at the output of most audio devices like door bells, mp3 players, radios etc to drive an speaker. Other than that it can also be used in the stages of audio amplifier circuits. When using as a switch it can drive relays, LEDs, high power transistors, ICs and other components in electronic circuits.

How to Safely Long Run in a Circuit

To get long term and stable performance from this transistor in your circuits always stay under its maximum specification values like do not drive load more than 150mA, do not operate load more than 50V DC (for good performance stay below 40V DC). Always use a suitable base resistor. A base resistor limits the extra amount of current going into the base of the transistor. always operate the transistor under 125 Celsius and store it in temperature above -65 Celsius and and below +150 Celsius.
