Below are the conditions where we can accept a return request. Raspberry Pi based project 2N2222A NPN BJTÄue to the type of products we sell, we accept limited returns. To use it as a Switch or amplifier, you just have to forward bias Base Emitter Junction but care should be taken to limit the base current as emitter can only allow up to 800mA of the current to power the device. The 2N2222A is very much similar to BC547 BJT and 2N3902 BJT except it can allow more current than BC547 and can dissipate 652mW of power. Collector-Emitter Voltage (V CE) is 40V.Continuous Collector current (I C) is 800mA.It can be used in switching applications with current up to 800mA, in speed control of motors, also it can be used in Darlington Pair. To bias a transistor, we have to supply current to base pin, this current (I B) should be limited to 5mA. The maximum amount of current that could flow through the Collector pin is 800mA, hence we cannot connect loads that consume more than 800mA using this transistor. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. they will start conducting as BJT will operate in Saturation Region. As it is an NPN transistor, so collector and emitter will be left open when no signal is at the base and when a signal is provided to the base terminal, then the emitter and collector will be closed i.e. The 2N2222A is a common NPN Bipolar Junction Transistor (BJT) is used for general purpose low power amplifying or switching actions. ![]()
