Pn2222 transistor

The PN2222 is a conjoint NPN bipolar junction transistor which is used for common persistence less power intensifying or swapping circuits applications. It is intended for low to intermediate current, squat power, intermediate voltage and can activate at a temperately higher speed.

Is PN2222 and 2N2222 the same?

PN2222 and 2N2222 are both NPN bipolar junction transistors, and they are interchangeable under most circumstances.

Is 2N2222A NPN or PNP?

The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications.

Where is 2N2222A transistor used?

The 2N2222A transistor is a common NPN BJT & it is mainly used in the applications of switching & amplifying with less power. This transistor is mainly designed for low power, low to medium current, medium voltage & works at fairly high speeds.

Can I use BC547 instead of PN2222?

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 much current can a PN2222 handle?

This device is for use as a medium power amplifier and switch requiring collector currents up to 500mA.

Is PN2222 a Mosfet?

PN2222A Overview It is an NPN type transistor with an operating temperature range of -55 to 150 degrees Celsius. The component can dissipate 625 mW of power, giving it good thermal control for not being a MOSFET, which is designed for thermal dissipation.

Can I use C945 instead of 2N2222?

As far as specs are concerned the C945 has more gain, Hfe, than the 2N2222, but for most applications yes you could use C945 in place of the 2N2222. One issue though is C945 has different pin out than the 2N2222. The 2N2222 base has pin out of emitter-base-collector (base is center pin).

Can I use 2N3904 instead of 2N2222?

The 2N3904 or 2N2222 will suffice if you require less than 200mA. The 2N2222 is the one to choose if you require more than 200mA but not more than 1A. For most circuits, a 2N3904 would suffice, however, if you need more above 200mA, a 2N2222 should be used instead.

Can I use PNP instead of NPN?

Generally, the PNP transistor can replace NPN transistors in most electronic circuits, the only difference is the polarities of the voltages, and the directions of the current flow. PNP transistors can also be used as switching devices and an example of a PNP transistor switch is shown below.

Should I use NPN or PNP?

A current flowing into the base of the NPN turns on the transistor whereas a current flowing out of the base turns on the PNP. Thus the most common use for NPN devices is for switching the ground side of a circuit. PNP devices are used to switch from the positive side.

Can I use a PNP sensor as NPN?

For example, you can use NPN sensors with an NPN Input card or “sourcing type” Input card. However, you can't use PNP sensors with an NPN input card.

What is the difference between 2N2222 and 2N2222A?

What are 2N2222 and 2N2222A Transistors? Both transistors are from the same family but the 2N2222A has higher Maximum absolute ratings than 2N2222. The Collector to Base, Emitter to Base, and Collector to Emitter voltage ratings of 2N2222 and 2N2222A are 60V, 30V, 5V, and 75V, 40V, 6V respectively.

How fast can a 2N2222 switch?

The 2N2222 has a combined rise-time, fall-time, and storage-time of 310ns, thus the maximum switching frequency is about 3MHz so it's not appropriate for this application.

How much voltage can a 2N2222 handle?

Both the 2N3904 and 2N2222 are identical in terms of handling collector-to-emitter voltages, and both can handle voltages of up to 40V. 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.

Why is BC547 used?

BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.

Which transistor can be used in place of BC547?

BC548, BC549, BC636, BC639, 2N2222 TO-92, 2N2222 TO-18, 2N2369, 2N3055 and 2N3904 all are BC547 transistor equivalent.

Can I replace a transistor with any other transistor?

Fortunately it is normally possible to use a replacement transistor type as there is often a considerable degree of overlap between the specifications of different types of transistor, and by looking at the basic specifications it is normally possible to choose the correct transistor replacements.

What is the maximum voltage a transistor can handle?

A typical value for a small signal transistor is 60 to 80 V. In power transistors, this could range to 1000 V, for example, a horizontal deflection transistor in a cathode ray tube display.

What is the most common NPN transistor?

A common NPN transistor is the 2N3904. You can easily switch big 12 or 16V loads with this 40V transistor. The current is rated at 200mA which is enough for many small DC motors, relay coils or LEDs. For high-side switch circuits, you need a PNP type transistor.
