The is a low voltage, low current, general-purpose switching transistor in a TO-92 package. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2N2222-type transistors in one package as an array of transistors. The P2N2222 has a different order of pins than the metal case 2N2222, with its emitter and collector connections switched other plastic-case transistors also have different pinouts. Replacements for the 2N2222 are commonly available now in the cheaper packaging, where it is known as the PN2222 or P2N2222, which has similar specifications except for the lower maximum collector current.
Other NPN switching transistors NPN silicon transistors with similar properties are also made in a variety of small through-hole and surface mount packages including, and SOT-223. Anda perlu memiliki catatan persamaan transistor sebab dalam merakit atau mereparasi mungkin sekali menjumpai transistor yang aus dan Anda tak menemukan seri yang sama.
