2N2219 Transistor Explained / Description

2N2219 is a perfect transistor if you are looking for a little bit high power general purpose transistor in place of general purpose TO-92 package transistor like 2N2222, BC547, 2N3904, C945, SS9013 etc. Also if you require a BJT transistor that have a higher operating temperature as compare to TO-92 package transistors mentioned above. Also you can use a suitable heatsink with the transistor in case of higher operating temperature.

When using it as a switch it can handle 800mA load that can drive multiple relays, LEDs, high power transistors and other components in a circuit. On the other hand it can also perform well as an amplifier for signal and audio amplification and the total collector dissipation of the transistor is 800mW.

2N2219 also perform well when using in RF circuits, its transition frequency is 250MHz therefore it can be used in RF circuitry that works under 250MHz.


Where We Can Use it & How to Use

2N2219 can be used for any general purpose application where you can use a normal TO-92 BJT transistor. It possesses fast switching capability due to which you can use it in your applications where fast switching is required. You can also use it as a switch for drive any type of load under 800mA. It can also be used as an amplifier in audio stages or it can be an output amplifier of any portable audio device to drive a speaker. Moreover it can also be used as a signal amplifier for any type of electronic signal amplification. Other than that it can also perform well in RF circuits and can be used in RF amplification and Oscillation circuits under 250MHz.

How to Get Long Term Performance in a Circuit

To achieve long term stable performance with this transistor, the user should not drive load more than 800mA with this transistor. Use a proper heatsink in applications in which the junction temperature of the transistor increases while operating. Do not operate load of more than 30V DC and always store and operate in surrounding temperature above -65 degree Celsius and below +150 degree Celsius.
