So if you want to use the BC547 in place of 2N2222 then it is important to check for what purpose the 2N2222 is used in that particular circuit whether it is used as a switch, amplifier, oscillator, or else. And the 2N2222 collector to emitter voltage is 40V, the collector current is 600mA, Total device dissipation is 625mW, DC current gain is 30 to 300, and transition frequency is 250MHz.Īs you know that a transistor is used for switching, amplification, oscillation etc. In the above table, you can see that the BC547 collector to emitter voltage is 50V, collector current is 100mA, Total device dissipation is 500mW, DC current gain is 110 to 800, and transition frequency is 300MHz. To understand this first we will compare the ratings and characteristics of these transistors. Ratings & Characteristics Comparison : Ratings & Characteristics So whenever we are replacing them we have the change the face in opposite side because the Collector and Emitter pins of the transistors are opposite to each other. BC547 transistor’s first pin is collector, second is base and third is Emitter while the 2N2222 transistor’s first pin is emitter, second is base and third is Collector. You can easily find these transistors in your local electronics store.By looking at the above pin comparison image above we can understand that pin configuration of both the transistors are different. 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. ![]() 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. 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. PN2222 Pinout Diagram Pin Name Description B Base Controls the transistor’s biasing, used to turn it on and off.
