How much voltage can a 2N2222A transistor handle?
The transistor 2N2222 or 2N2222A are NPN types and has the following electrical parameters: The device’s maximum voltage tolerance (breakdown voltage) across its collector and base is 60 volts for 2N2222 and 75 volts for 2N2222A, with the emitters kept open.
How does a 2N2222A transistor work?
2N2222A transistor offers constant DC collector current like 800mA, so it is necessary to use where low to medium current is necessary. It functions on the value of high transition frequency like 250MHz through 10ns delay time, 225ms storage time, 60ms fall time & 25ms rise time. It is available in the TO-92 package.
How many watts can a 2N2222 handle?
It’s a current controlled transistor. It has a Collector current of 800 mA. Power Dissipation of 2N2222 is 500mW. It can operate between -65 C to 200 C temperature.
What is the difference between 2N2222 and BC547?
The 2N2222 has an emitter, base, and collector pinout, whereas the BC547 has a collector, base, and emitter pinout. The collector to base voltage at 2N2222 is 60 volts, whereas it is 50 volts at BC547, and the collector to emitter voltage is 30 volts at 2N2222 vs 45 volts at BC547.
Can I use 2N2222 instead of 2N2222A?
The 2N2222A is the “improved” version of the 2N2222. You should be able to substitute the former for the latter in any circuit (but not necessarily vice versa). I would suspect that you wouldn’t be able to find a supplier of the 2N2222 these days since the A version has been around for a long time.
How many amps can 2N2222 handle?
2N3904 vs 2N2222
| 2N3904 | 2N2222 | |
|---|---|---|
| Type of BJT | NPN | NPN |
| Maximum current that the transistor can handle from the emitter to the collector (called collector current, Ic) | 200mA | 1A |
| Maximum voltage that the collector of the transistor can handle (called the collector-emitter voltage, VCEO) | 40V | 40V |
Can I use 2N2222A instead of BC547?
The 2N2222 and BC547 transistors are general-purpose transistors that are commonly used in electrical circuits; the BC547 transistor is one of the best transistor counterparts which can interchange with 2N2222 transistor.
Can I use a BC547 transistor instead of a 2n2222a transistor?
Product Datasheet. Can we use BC547 instead of 2N2222? Yes, you can use, for switching just look for Ic(collector current) and Vceo(collector-emitter voltage) in the datasheet.
How do you set up a transistor circuit?
To connect the transistor as a switch in a circuit, we connect the output of the device that will switch on the transistor to the base of the transistor. The emitter will connect to ground of the circuit. And the collector will connect to the load that the transistor will turn on and the supply voltage of the circuit.
Which transistor can be used in place of 2n2222a?
The 2N2907 is an equally popular PNP transistor complementary to the 2N2222.
