2N2222A NPN Transistor

Fr 300.00

2N2222A is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. 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. To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 5mA.

Description

Specifications

  • Bi-Polar high current NPN Transistor
  • DC Current Gain (hFE)is 100
  • Continuous Collector current (IC) is 800mA
  • Emitter Base Voltage (VBE) is 6V
  • Collector Emitter Voltage (VCE) is 30V
  • Base Current(IB) is 5mA maximum
  • Available in To-92 Package

Where to use 2N2222A

The 2N2222A transistor is very much similar to the commonly used NPN transistor BC547. But there are two important features that distinguish both. 2N2222A can allow collector current up to 800mA and also has power dissipation of 652mW which can be used to drive larger loads than compared with BC547.

So if you looking for an NPN transistor that could switch loads of higher current, then 2N2222A might the right choice for your project.

Applications

  • Can be used to switch high current (up to 800mA) loads
  • It can also be used in the various switching applications.
  • Speed control of Motors
  • Inverter and other rectifier circuits
  • Can be used in Darlington Pair.
