Embedded and automation projects Where to Buy PN2222 and PN2222A?.The applications of the PN2222 transistor are in : To download the datasheet of PN2222A, click here. To download the datasheet of PN2222, click here. A small transistor like the PN2222 can be used as a switch that uses just a little current from the Arduino digital output to control the much bigger current of the motor. Electrically Similar to the Popular 2N2222A transistor. Given below is the list of transistors that are equivalent to the PN2222 transistor: Operating and Storage Junction Temperature Range: -55 to +150 ☌. 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. It was originally made in the TO-18 metal can as shown in the picture. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. PN2222 VS PN2222A: What’s the difference?īoth are similar types of transistors but the PN2222A has higher Maximum absolute ratings than PN2222. The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. 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.

Given below are the specifications of PN2222 and PN2222A transistors in a tabular form. E Emitter Current comes out of transistor through the emitter, usually grounded. C Collector Current flows through the collector, usually connected to a load.
