Note: Some companies call 2N2222 transistor "2N2222A' now and manufactures 2N2222A only.\$3.3\:\text\$ can be estimated from a datasheet or from a simulation. 2N2222 / 2N2222A NPN Silicon Epitaxial Planar Transistor for switching and AF amplifier applications. Parecidos a este podrian ser BC337, BC365, ZTX450. 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. Ya es raro no encontrar el 2n2222, almenos aquí en españa te lo encuentras hasta debajo las piedras. 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. Pricing and Availability on millions of electronic components from Digi-Key Electronics. The other absolute maximum ratings are similar.

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.
