Due to this reason, the current rating of 2N2222A is slightly lower than 2N2222.ĭue to different packaging, their pinout also differs, as shown below. The Collector to Base, Emitter to Base, and Collector to Emitter voltage ratings of 2N2222 and 2N2222A are 60V, 30V, 5V, and 75V, 40V, 6V respectively.Īlso, the 2N2222 comes in metal packaging whereas the 2N2222A is available in TO-92 plastic enclosure also. It’s important to note that both transistors have their updated versions with alphabet ‘A’ at the end i.e, 2N2222A and PN2222A What are 2N2222 and 2N2222A Transistors?īoth transistors are from the same family but the 2N2222A has higher Maximum absolute ratings than 2N2222. The other absolute maximum ratings are similar. PN2222 is the TO-92 plastic version of 2N2222, hence ‘P’ in PN2222.ĭue to the plastic enclosing, the collector power dissipation and storage temperature ratings of PN2222 is less than 2N2222. What are PN2222 and PN2222A Transistors?ĢN2222 transistor is the original one whereas PN2222 is its updated version.What are 2N2222 and 2N2222A Transistors?.Please go through the dedicated datasheet provided by the manufacturer before using 2N2222. This table compares the specs of 2N2222 variants Note: These value may vary according to the manufacturer. Here are the differences between all four of them in a tabular form: Parameter Due to this, there is a lot of confusion among beginners regarding which one to choose and what’s the difference.īut in this post, we are going to put an end to this confusion once and for all by comparing 2N2222 VS PN2222 VS 2N2222A VS PN22222 in detail. But there are many variants of this transistor in the market, mainly 2N2222A, PN2222, and PN2222A. 2N2222 is one of the most popular and commonly used transistors in electronics projects.
