2N2222A Datasheet – 40V, 800mA, NPN Transistor

This post explains for the transistor.

Part Number: 2N2222A

Function: Silicon Planar Epitaxial NPN Transistor

Package: TO-18

Manufacturer: STMicroelectronics


2N2222A npn transistor


This is 40V, 800mA, NPN Transistor.

The 2N2219A and 2N2222A are silicon Planar Epitaxial NPN transistors in Jedec TO-39 (for 2N2219A) and in Jedec TO-18 (for 2N2222A) 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.
