![]() This feature makes it ideal for electronics projects like controlling high-power LEDs, relays, high-power transistors, and ICs. This table show differences between BC547 and 2N2222ĢN2222 is used in a variety of electronic projects due to its excellent features like a larger collector current 600mA. Other differences between both transistors are given below: Spec This affects the circuit while operating at a higher frequency. The input and output capacitance of 2N222 is slightly higher than BC547. ![]() Are there any differences between 2N2222 and BC547 Transistor?īetween BC547 & 2N2222, there are minor changes in output and input capacitance. Although using an equivalent transistor requires a detailed comparison, the BC547 is still a good alternative to 2N2222. BC547 transistor is considered the best equivalent of 2N2222 & can work well in your projects. Given below is the list of transistors that are equivalent to 2N2222 and can be used as a replacement. Which transistors are equivalent to 2N2222? Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. The exact specifications depend on the manufacturer, case type, and variation. This table shows the technical specifications of the 2N2222 Transistor The technical specifications of 2N2222 in TO-18 metal packaging and 2N2222A transistor in TO-92 packaging are given below: Spec 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 only.ĢN2222A is a better option considering its higher ratings, low cost, and TO-92 packaging. The emitter is denoted by ‘ E’.ĢN2222 VS 2N2222A: What’s the difference?īoth are similar types of transistors but the 2N2222A has higher Maximum absolute ratings than 2N2222. This pin act as an outlet and the current comes out of the transistor from here. This pin controls the transistor biasing. This pin act as an inlet as the current enters the transistor from here. To download the datasheet just copy and paste the below link in your browser.Original 2N2222 Pinout(TO-18 Package) Pin ![]() Use a suitable heatsink with the transistor and always store and operate the transistor at temperature above -65 degree centigrade and below 200 degree centigrade. The maximum collector to emitter voltage is 30 so do not drive load of more than 24V. The maximum collector current of the transistor is 800mA therefore do not drive load of more than 640mA. Understanding the absolute maximum ratings of a component is also very important and using a component on its absolute maximum ratings is also not suggested by its manufacturers therefore we suggest using a component atleast 20% below from its absolute maximum ratings. Safe Operating Guidelines / Absolute Maximum Ratings: The maximum transition frequency is UP to 300MHz due to which this transistor can also be used in radio and RF circuits under 300MHz. Other than that it can also be used as a switch to drive load of upto 800mA. When working as an amplifier it can be used in audio amplification circuits, audio preamplification circuits and any type of small signal amplification in electronic application. More over the maximum DC current gain is 50 to 300 and the maximum transition frequency is upto 300MHz.ĢN2222 is a general purpose transistor with lot of capabilities in a small package. Moreover it has an also high speed switching capability which makes it ideal to use in applications in which high speed switching is crucial. ![]() When looking at its collector to emitter voltage or voltage load voltage capabilities it maximum collector to emitter voltage is 30V which means it can drive load voltage of upto 30V. When looking at its switching capabilities it can drive load of upto 0.8A or 800mA a little bit higher than its plastic version which has 500mA to 600mA collector current or current load driving capability. The transistor performs well in both regions which are switching and amplification. Also these transistors are available two different packages which are TO-92 and TO-18, but in this post we are going to discuss 2N2222 TO-18 metal can transistor in detail. The transistor is available in many different part numbers and which are 2N2222, 2N2222A, PN2222, PN2222A and all the part numbers are slightly different from each other in specs.
