2N5459 Transistor Explained / Description:

2N5459 is an N Channel JFET transistor; the transistor is manufactured to use in general purpose applications such as switching and amplification. The transistor possesses some of very good low noise and high gain features which make it ideal to use in applications were a user want to amplify a low gain signal to high gain with good noise filtrations at the output. Other than that it can also be used to amplify any type of general purpose audio and other signal amplification. This transistor can also be used as a switch and the max load the user can drive is 10mA.

Where We Can Use it & How to Use:

As mentioned above 2N5459 transistor can be used in circuits where low noise and high gain signal amplification is required. So the transistor can be used in audio preamplifiers, audio amplifier stages, sound detector circuits, variety of light sensor circuits etc. Moreover this transistor can also be used as a switch and the max load user can drive is 10mA.

Applications:

Audio Preamplifiers

Audio Amplifiers

Variety of Sensor Applications

Amplification of any type of low gain signals

How to Safely Long Run in a Circuit:

For long term stability and performance of a component we always suggest using it atleast 20% below from its maximum ratings, therefore same goes with the 2N5459 transistor. The maximum drain to source voltage is 25V therefore do not drive load of more than 20V. The maximum continuous gate current is 10mA therefore do not drive load of more than 8mA and always operate this transistor in temperature above -55 degree centigrade and below +150 degree centigrade.
