It is used in numerous swapping submissions. It is used where higher current consumer loads in the circuit. Notice that in this circuit motor consumes around 500mA by the 12V supply source, meanwhile the PN2222 rating of the collector up to 800mA, which shows the importance that if we have BC547 in the circuit it would be damaged. In this circuit, I supplied five volts to the base and 1K resistor to limit the current. In a real circuit, alterations must be vital. To mark things modest, I have exposed a basic circuit of the transistor as a switch. Its value can be found by the given equation. This resistor in the circuit is for limit the coming current which can damage the transistor. One important thing in this circuit is the base resistor which is a current preventive resistor. This will change it to forward biasing and consequently completions the linking between collector and emitter. Voltage crossways of base and emitter are six volts, so we have to apply these voltage crossways base and emitter to persuade a base current of the transistor. Like other transistors, PN2222 can be used as an amplifier and switch.
So if you are considering for an NPN transistor which can switch loads of large current user, then PN2222 will be the right option for your industrial developments. Due to this, it is used for larger loads then BC547. It can permit collector current up to 800mA and as well has power intemperance of 652mW. Nevertheless, there are two significant topographies which differentiate both of them.
PN2222, just like the generally used NPN transistor BC547. Secondly, gain and leakage characteristics, PN2222A is properly a repackaging of 2N2222A, a better version of 2N2222. For most purposes, they are interchangeable.īut there are subtle differences between them.įirstly, package, PN2222 is in a molded-epoxy TO-92 2N2222 is in a TO-18 metal can. Same as PN2222, it can be used for amplification of analog signals as well as switching applications. Small Signal Bipolar Transistor, 0.6A I(C), 30V V(BR)CEO, 1-Element, NPN, Silicon, TO-92, LEAD FREE, TO-92, 3 PINĦ00mA, 30V, NPN, Si, SMALL SIGNAL TRANSISTOR, TO-92, LEAD FREE, TO-92, 3 PINĢN2222 is the most common NPN bipolar junction transistor available in the market. Small Signal Bipolar Transistor, 0.6A I(C), 30V V(BR)CEO, 1-Element, NPN, Silicon, TO-92, TO-92, 3 PIN It has a functioning and storing connection temperature range -55 to +150 ☌.ĥ00mA, 30V, NPN, Si, SMALL SIGNAL TRANSISTOR, TO-92 Its collector intemperance factor is 0.625 W. Its voltage between collector and emitter is thirty volts. Its (VBE) Emitter-base voltage is six volts. Its incessant Collector current (IC) is 800mA. It is bi-polar higher current user NPN transistor.
The base controls the biasing of the transistor. The emitter is for the current inward movement. Anyway, hope this blog helps and thanks for reading! This blog covers the basic information of PN2222 from its pinout, features, equivalents to its use, working principle, and its difference between 2N2222 and so on. PN2222 is a conjoint NPN bipolar junction transistor which is used for common persistence less power intensifying or swapping circuits applications.
