Download the 2N2221 datasheet PDF. This datasheet also covers the 2N2218 variant, as both devices belong to the same high-speed switches family and are provided as variant models within a single manufacturer datasheet.
The 2N2218, 2N2219, 2N2221 and 2N2222 are silicon planar epitaxial NPN transistors in Jedec TO-39 (for 2N2218 and 2N2219) and in Jedec TO-18 (for 2N2221 and 2N2222) metal cases.
