How much voltage can a 2N2222 handle?

How much voltage can a 2N2222 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.

In which device 2N2222 transistor is used?

2N2222 NPN transistor has been commonly used for switching and very high frequency(VHF) amplifier applications. It is made of silicon material and specially designed for low voltage, low to medium current and low power amplifier applications.

What is emitter base and collector?

The base is the gate controller device for the larger electrical supply. The collector is the larger electrical supply, and the emitter is the outlet for that supply. By sending varying levels of current from the base, the amount of current flowing through the gate from the collector may be regulated.

What is the difference between emitter base and collector?

The emitter-base circuit is in forward biased and offered the low resistance to the circuit. The collector-base junction is in reverse bias and offers the higher resistance to the circuit. The base of the transistor is lightly doped and very thin due to which it offers the majority charge carrier to the base.

What is the difference between 2N2222 and 2N2222A?

The following datasheet shows the difference between the two transistors: bytesonic.com/sonic/2N2222.pdf The major difference that I see is that the 2N2222A has higher voltages for the Vebo, Vcbo and Vceo values.

What is General Purpose transistor?

The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. It was originally made in the TO-18 metal can as shown in the picture.

Can I use BC547 instead of 2N2222?

The 2N2222A transistor is very much similar to the commonly used NPN transistor BC547. 2N2222A can allow collector current upto 800mA and also has power dissipation of 652mW which can be used to drive larger loads than compared with BC547.

Why base current is weaker than collector current?

Explanation: Base is much narrower and thinner than collectors,hence the majority of charge carriers are received by collector. Hence,collector current is greater than base current..

Why does a transistor have 3 legs?

The transistor has three legs, these are the base, collector and the emitter. The base of the transistor is used to switch current through the collector and emitter. When the base is between 0V and 0.7V it is switched off and above 0.7V it is switched on allowing the current to flow from the collector to the emitter.

What are the 3 parts of a transistor?

There are typically three electrical leads in a transistor, called the emitter, the collector, and the base—or, in modern switching applications, the source, the drain, and the gate.

What is the DC collector current of 2N2222?

It is made of silicon material and specially designed for low voltage, low to medium current and low power amplifier applications. 2N2222 provides continuous dc collector current is 800mA. It means it has a high collector therefore it is mostly used in that circuits where low to medium current is required.

What are the characteristics of a BJT 2N2222 transistor?

The main characteristics of this device may be understood with the following points: · 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.

What should the trigger voltage be for a 2N2222A?

With collector current exceeding 500 mA, the base optimal trigger voltage becomes 2.6 volts. For a 2N2222A, the figures are 1.2 and 2 volts respectively. This may be done by following the below explained steps:

Is the 2N2222 a PNP or NPN transistor?

The BC548 is a low voltage, low current, general-purpose switching transistor in a TO-92 package. The 2N2907 is an equally popular PNP transistor complementary to the 2N2222. The 2N3904 is an NPN transistor that can only switch one-third the current of the 2N2222 but has otherwise similar characteristics.
