2n2222 transistor characteristics12/8/2023 ![]() Note: Some companies call 2N2222 transistor "2N2222A' now and manufactures 2N2222A only. ![]() Due to this reason, the current rating of 2N2222A is slightly lower than 2N2222.ĭue to different packaging, their pinout also differs, as shown below. 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 also. 16344 In todays blog, we are going to discuss 2n2222s pinout, applications, equivalents, example circuits and where and how to use this device, etc. It’s important to note that both transistors have their updated versions with alphabet ‘A’ at the end i.e, 2N2222A and PN2222A What are 2N2222 and 2N2222A Transistors?īoth transistors are from the same family but the 2N2222A has higher Maximum absolute ratings than 2N2222. The other absolute maximum ratings are similar. It was originally made in the TO-18 metal can as shown in the picture.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 is the TO-92 plastic version of 2N2222, hence ‘P’ in PN2222.ĭue to the plastic enclosing, the collector power dissipation and storage temperature ratings of PN2222 is less than 2N2222. The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. 2N2222 Transistor Applications PN2222 VS 2N2222: Short answerĢN2222 transistor is the original one whereas PN2222 is its updated version.What are PN2222 and PN2222A Transistors?.What are 2N2222 and 2N2222A Transistors?.Functional operation above the Recommended Operating Conditions is not implied. Please go through the dedicated datasheet provided by the manufacturer before using 2N2222. Features These are PbFree Devices MAXIMUM RATINGS (TA 25C unless otherwise noted) THERMAL CHARACTERISTICS Stresses exceeding Maximum Ratings may damage the device. ![]() Here are the differences between all four of them in a tabular form: Parameter 2N2222 2N2222A PN2222 PN2222A Collector-Base Voltage(V CBO) 60 V 75 V 60 V 75 V Collector-Emitter Voltage(V CEO) 30 V 40 V 30 V 40 V Emitter-Base Voltage(V EBO) 5 V 6 V 5 V 6 V Collector Current(I C) 0.8 A 0.6 A 0.6 A 1 A DC Current Gain(h FE) 300(Max) 300(Max) 300(Max) 300(Max) Output Capacitance(C OBO) 8 pF 8 pF 8 pF 8 pF Collector Power Dissipation(P C) 1.2W 1.5W 625 mW 625 mW Storage Temperature(T STG) -65 to 200☌ -55 to 150☌ -55 ~ 150 ☌ -55 ~ 150 ☌ Package TO-18 TO-92 TO-92 TO-92 This table compares the specs of 2N2222 variants Note: These value may vary according to the manufacturer. Due to this, there is a lot of confusion among beginners regarding which one to choose and what’s the difference.īut in this post, we are going to put an end to this confusion once and for all by comparing 2N2222 VS PN2222 VS 2N2222A VS PN22222 in detail. This one, identifiable by its metal cover (TO98), is. This example shows generation of the Ic versus Vce curve for an NPN bipolar transistor. But there are many variants of this transistor in the market, mainly 2N2222A, PN2222, and PN2222A. The NPN 2N2222 transistor is a variant of the famous P2N2222AG with some variations in its characteristics. 2N2222 is one of the most popular and commonly used transistors in electronics projects.
