![]() You can easily find these transistors in your local electronics store. The applications of the PN2222 transistor are in : To download the datasheet of PN2222A, click here. To download the datasheet of PN2222, click here. Given below is the list of transistors that are equivalent to the PN2222 transistor: The cost is almost the same, so PN2222A is a better option considering its higher ratings. The Collector to Base, Emitter to Base, and Collector to Emitter voltage ratings of PN2222 and PN2222A are 60V, 30V, 5V and 75V, 40V, 6V respectively. ![]() PN2222 VS PN2222A: What’s the difference?īoth are similar types of transistors but the PN2222A has higher Maximum absolute ratings than PN2222. There are two versions of PN2222: PN222A (which has higher Absolute Maximum Ratings) and the original model without an ‘A’ at the end – this denotes that it exists as a cheaper version of the 2N2222 transistor. The emitter 'emits' electrons into the base, which controls the number of electrons the emitter emits. It comes in TO-92 packaging, with 60 V Collector-Base, 30 V Emitter-Base, and 5 V Collector-Emitter voltage ratings. The NPN transistor is designed to pass electrons from the emitter to the collector (so conventional current flows from collector to emitter). PN2222 is an NPN general-purpose transistor that is complementary to the PN2907 PNP transistor. Specifications of PN2222 Transistor What is a PN2222 Transistor?
