Text: 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. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.2N2222A 338 Datasheets Context Search Catalog DatasheetĪbstract: 2N2222 application note 2N2222 of 2N2222A Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. 2N2222A is a semiconductor device used to amplify or switch electronic signals and electrical power.
