2n2222 transistor specifications12/6/2023 ![]() The 2222 transistor is a common NPN bipolar junction transistor. As a switch, the 2N2222 transistor can use to turn on or off a load. As an amplifier, the 2N2222 transistor can use to increase the strength of a signal. The 2N2222 can use as either an amplifier or a switch. ![]() A small current applied to the base terminal can cause a much larger current to flow between the collector and emitter terminals. The base terminal controls the flow of current between the collector and emitter terminals. The Complementary Transistor 2N2222 has three terminals: the base, the collector, and the emitter. BJTs work by controlling the flow of current through a semiconductor material using a small amount of current at a different point in the semiconductor. ![]() The 2N2222 transistor is a bipolar junction transistor (BJT). This means that the voltage difference between the base and emitter terminals of the transistor should not exceed 6 volts. The 2N2222 transistor also has a maximum base-emitter voltage of 6 volts. The NPN transistor 2N2222 has a maximum collector-emitter voltage of 40 volts. It is frequently use as a small-signal transistor, and it remains a small general purpose transistor of enduring popularity. 2N2222 A331 Transistor is design for low to medium current, low power, medium voltage, and can operate at moderately high speeds. The 2N2222 is a common NPN bipolar junction transistor (BJT) use for general purpose low-power amplifying or switching applications. Transistor NPN 2N2222 is a popular choice for hobbyists and professionals alike due to its low cost, easy availability, and wide range of capabilities. *This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.T he 2N2222 transistor is a versatile and reliable NPN Switching Transistor that can use in a wide variety of electronic circuits.
