2N2222 / 2N2222A

by admin on December 5, 2017

General Purpose NPN Transistor

2N2219A, 2N2221 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 and small signal applications 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.
