Where We Can Use it & How to Use:

As mentioned above 2N5457 is designed for amplification purposes therefore it can be used in amplification of different type of low level signals whether it will be an audio signal or other type of signals in electronics. Other than that it can also be used as a switch and it can handle max load of 10mA.

 

Applications:

Audio Preamp circuits

Any Low Level Signal Amplification

Sensor Circuits

Audio Amplifier Stages

Infrared Detection

 

How to Safely Long Run in a Circuit:

To get good performance with 2N5457 it is recommended to always stay below the maximum ratings. Do not drive load of more than 10mA, do not operate the load of more than 25V through this transistor, do not increase drain to gate voltage from 25V reverse gate to source voltage should not be increased from -25V, and always operate and store the transistor above -55 centigrade and below +150 centigrade.
