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. It comes in TO-92 packaging, with 60 V Collector-Base, 30 V Emitter-Base, and 5 V Collector-Emitter voltage ratings. PN2222 is an NPN general-purpose transistor that is complementary to the PN2907 PNP transistor. Specifications of PN2222 Transistor What is a PN2222 Transistor? Given below are the specifications of PN2222 and PN2222A transistors in a tabular form.
Controls the transistor’s biasing, used to turn it on and off.Ĭurrent flows through the collector, usually connected to a load.Ĭurrent comes out of transistor through the emitter, usually grounded.
