![]() ![]() 2N3904 can handle up to 200mA (milliamperes) of current flowing from the emitter to the collector terminal. Collector current is the amplified current that flows from the emitter to the collector to power the load that may be connected to the transistor. Where they differ is that the 2N2222 can handle larger operating collector currents. since the 2N3904 and 2N2222 have the same maximum VCEO voltage, there is no difference in this regard. this would not be acceptable because it exceeds the maximum VCEO. ![]() For example, suppose we apply 70V to the collector of the transistor and the load will consume 20V, this means that the remaining voltage will fall on the transistor which will be 70V - 20V = 50V. In simple terms, this effectively means that 40V is the maximum amount of voltage that the transistor can handle minus the voltage drop across the load connected to the collector. Maximum current that the transistor can handle from the emitter to the collectorīoth the 2N3904 and 2N2222 are identical in terms of handling collector-to-emitter voltages, and both can handle voltages of up to 40V. (called the collector-emitter voltage, VCEO) Maximum voltage that the collector of the transistor can handle This is a comparison table of transistors, which explains the meaning of everything in the table.Ģ.1 Specifications of 2N2222 Motor Driver ICģ.1 Specifications of 2N2222 Motor Driver IC Therefore, some people may have questions: Why is 2N3904 so popular and 2N2222 is not always used? If you are curious about which one to use, or which is better, which is better? In this blog, we will compare the chip characteristics and pin diagrams of these two transistors.Ĭomparing transistors is not extensive, because only a few useful parameters are important. In addition, 2N3904 and 2N2222 are similar in appearance. 2N3904 and 2N2222 are the two most popular NPN bipolar junction transistors in the electronics market. ![]()
