2N3819 Transistor Explained / Description:

2N3819 is a TO-92 packaged JFET transistor built for VHF and UHF applications. The transistor possesses some very good features like very low noise and distortion, high gain and sensitivity, quality signal amplification and can also be used for very low level signal amplification. Other than that it can also be used as a switch. When used as a switch it is capable of fast switching and can drive loads that falls under 10mA. It also provides high gain at 100MHz.

Where We Can Use it:

As described above 2N3819 is mostly built for VHF and UHF applications, Due to its low noise feature, it can be used for 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. Moreover it also features high gain at 100MHz which also makes it ideal to use in RF applications.

Applications:

VHF & UHF applications

Any Low Level Signal Amplification

Sensor Circuits

Audio Amplifier Stages

Jfet 2n3819

How to Safely Long Run in a Circuit:

For long term stable performance of 2N3819 it is recommended to always stay 20% below from the max ratings. Does not drive load of more than 10mA through this transistor and the load voltage should be under 25V. Always store and operate it in temperature above -65 Celsius and below +150 Celsius.
