2N2222A Transistor – NPN Transistor

Part number : 2N2222A

Functions : NPN Amplifier Transistor, High Speed Switche

Package : TO-92 type , TO=18, TO-39 Can type

Manufacturer : ON Semiconductor , STMicroelectronics


2N2222A transistor


The 2N2222A is a common NPN bipolar junction transistor used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds.

The 2N2219A and 2N2222A are silicon Planar Epitaxial NPN transistors in Jedec TO-39 (for 2N2219A) and in Jedec TO-18 metal case. They are designed for high speed switching application at collector current up to 500mA, and feature useful current gain over a wide range of collector current, low leakage currents and low saturation voltage.
