2N2219A 2N2222A
HIGH SPEED SWITCHES

DESCRIPTION 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 lowsaturation voltage. 2N2219A approved to CECC 50002-100, 2N2222A approved to CECC 50002-101 available on request. TO-18 TO-39
