2n2222 transistor pinout

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 It was originally made in the TO-18 metal can as shown in the picture.

Which transistor is equivalent of 2N2222?

2N2222 Equivalents 2N3904, BC547, BC548, and 2N3906 are 2N2222 comparable transistors.

How can use 2N2222 transistor as a switch?

The 2N2222 transistor is used as a switch in this circuit, with an input resistor driving the transistor and another resistor driving the LED. The transistor starts to work when the switch is closed, and the LED ON and OFF intervals are controlled by the resistance value.

Are 2N2222 and 2N2222A same?

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 much power can a 2N2222 handle?

Power Dissipation of 2N2222 is 500mW. It can operate between -65 C to 200 C temperature. Collector base voltage of 2n2222 is 60.

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.

Can a 2N2222 replace 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.

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.

Can we use BC547 instead of 2N2222 in Tesla coil?

Yes you can use a BC547 transistor instead of 2N2222 in your tesla coil circuit.

Can you use a transistor without a resistor?

A transistor without a resistor on the base is like an LED with no current-limiting resistor. Recall that, in a way, a transistor is just a pair of interconnected diodes. We're forward-biasing the base-emitter diode to turn the load on. The diode only needs 0.6V to turn on, more voltage than that means more current.

Why use a transistor instead of a switch?

Transistors: Speed and Simplicity Transistors allow current to flow between the collector and emitter, as opposed to an on/off switch. They use no moving parts.

Can I use a transistor as a relay?

The transistor here is serving the same function as the relay. However, it can switch much faster than the relay. In addition, because there are no mechanical parts, it will reliably function for more switching operations than the relay. However, current can only flow in one direction through a transistor.

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.

What is the smallest transistor ever made?

Now, by using atomically thin materials, scientists in China have created a transistor with a record-breaking gate length of just roughly one-third of a nanometer wide, only as thick as a single layer of carbon atoms, shedding light on how much smaller—if at all—transistors can possibly get.

What is the most powerful transistor?

As of 2022, the highest transistor count GPU is Nvidia's H100, built on TSMC's N4 process and totalling 80 billion MOSFETs.

What is the cost of 2N2222 transistor?

₹55.00 FREE Delivery.

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.

How much voltage is needed to trigger a transistor?

Note in the formula above, that VBE(sat) is the required base voltage that must be present in order to forward-bias the transistor's base/emitter junction (i.e., to turn the transistor on). Generally speaking, this value is between . 6 to . 7 volts for a general-purpose transistor.

Can a transistor handle 12 volts?

If you're using 12V, you shouldn't have a problem with this. NPN (and PNP) transistors look like a diode from the base to the emitter. If you try to drive it without someway to limit the current, the transistor will be destroyed.

Can a transistor be bypassed?

If you add base resistors to both transistors, there is no risk in bypassing the transistors in your diagram. You basically turn the transistor in a diode and you have to limit the base current / GPIO-pin current from your microcontroller as the base-emitter voltage will be about 0.7V.
