The 2n2222ahr is a silicon planar npn transistor specifically designed and housed in hermetic packages for aerospace and hirel applications. Surge the transistor is subdivded into one group,alldatasheet, datasheet, datasheet search site for electronic components and semiconductors, integrated circuits, diodes, triacs, and other semiconductors. The 2n2222a is a slight bit better in terms of vceo, vcbo, vebo. Advance information formative or in design this datasheet contains the design specifications for product development. Semiconductor reserves the right to make changes at any time without notice in order to improve design. The base goes to the source voltage or the triggering voltage via a current limiting resistor. The 2n2222 pinout diagram is as shown in the picture below. The 2n2222 is a common npn bipolar junction transistor used for general purpose lowpower amplifying or switching applications.
The 2n2222 part is the older style part which might be the reason they are being offered at a low price. They are designed for high speed switching application. Single transistors are also available in several different surface mount packages, and a number of manufacturers market sd mount packages that incorporate several 2ntype transistors in one package as an array of transistors. The value of the current limiting resistor may be calculated by using the formula explained at the end of this article the transistor 2n2907 is complementary pair for 2n2222 and has identical specs as above, however being a pnp type the associated polarities are exactly opposite. But if you are not planning on stressing the part higher voltages, etc both will work well, especially for simple switching and logic circuits. It was originally made in the to18 metal can as shown in the picture the 2n2222 is considered a very common transistor, and is used as an exemplar. Datasheet identification product status definition.
