2N2222A NPN Transistor (Pack of 5)

The PN2222A is a common NPN BJT used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, and medium voltage, and can operate at moderately high speeds.

2N2222A is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.

The 2N2222 NPN Transistor is made in the TO-18 metal can as shown in the picture. Replacements are commonly available now in the cheaper TO-92 packaging, where it is known as the PN2222 or P2N2222, which has similar specifications except for the lower maximum collector current.

Applications:

  • This transistor can be used as a switch for automatically switch ON/OFF any appliances.
  • It is used for PWM due to its quick response
  • Because of its fast response time, it can be used for pulse width modulation.
  • Home automation & embedded projects.
  • Audio Preamplifiers
  • Audio Amplifier Stages
