2n2222a Bipolar Junction Npn Transistor

2N2222A Bipolar Junction NPN Transistor is commonly used in general-purpose low-power amplifying/switching applications. Bipolar Junction NPN Transistor is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. It was originally made in the TO-18 metal can as shown in the picture. We have many other NPN transistor like BD139, BC547, BC548, 2SC945 etc.The 2N2222 is considered a very common transistor and is used as an exemplar of an NPN transistor. It is frequently used as a small-signal transistor, and it remains a small general-purpose transistor of enduring popularity.

Features of 2N2222A Bipolar Junction NPN Transistor:

1. Use in a wide variety of electronic projects, the large 600mA collector current makes this transistor ideal to use it in your electronic projects to control relays, high power LEDs, other high power transistors and ICs at the same time.
2. 2N2222A can also be used to amplify audio signals, for example, it can be used in audio preamplifier stages and also in audio amplifier stages. It can also be used as a small audio amplifier or to drive a small speaker in electronic projects.
