3906 pinout

The 2N3906 is a commonly used PNP bipolar junction transistor intended for general purpose low-power amplifying or switching applications. It is designed for low electric current and power and medium voltage, and can operate at moderately high speeds.

What is the difference between 2N3904 and 2N3906?

As people said that the basic difference between 2N3904 and 2N3906 is that former is NPN transistor and later is PNP.

Which transistor is equivalent to BC547?

BC547 Equivalents The BC series, such as BC549 and BC639, are the finest recommendations for the BC547 transistor equivalent, followed by the 2N2222 transistor. BC636 replaces BC547, 2N2369, 2N3055, 2N3904, 2N3906, and 2SC5200 in the PNP.

How does a 2N3906 transistor work?

Working of 2N3906 The PNP transistor is essentially two diodes joined back to back. It consists of two PN junctions i.e. emitter-base junction and collector-base junction. The emitter-base junction is forward biased and responsible for the conduction in the transistor and carries small resistance.

Can you convert PNP to NPN?

e.g. how does one convert a PNP transistor to its NPN equivalent? It may be possible to use one for the other in a given circuit with a small design change, but what you're asking is not possible, there is no conversion to make a NPN into a PNP.

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.

Can I use 2N2222 instead of 2N3904?

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 BC547 instead of 2N3904?

The collector current of 2N3904 is 200mA and BC547 is 100mA therefore if the load you are driving with the 2N3904 is under 100mA then you can replace it with BC547 but if the load is above 100mA then you can not use BC547 instead of 2N3904.

Is 2N3904 NPN or PNP?

Since the 2N3904 is an NPN transistor, that means the base needs positive biasing (appropriate voltage levels and resistance) to turn on the collector emitter junction for proper current flow.

What type of transistor is a 3906?

The 2N3906 is a very popular Bipolar Transistor. It is a PNP Transistor with very high collector – emitter voltage (-40V) and relatively low collector current (-200mA). We can use this transistor as a low-power amplifier as well as a fast-switching transistor.

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.

What are the 3 basic terminals of a transistor?

A transistor is an electronic device that contains three terminals named emitter, base, and collector.

What are the 3 layers of a transistor?

It has three terminals that carry electrical current and help make a connection to external circuits: the emitter, also known as the transistor's negative lead, the base, which is the terminal that activates the transistor, and. the collector, which is the transistor's positive lead.

What are the 3 function of transistors?

transistor, semiconductor device for amplifying, controlling, and generating electrical signals.

Is NPN negative or positive?

PNP sensors produce a positive output to your industrial controls input, while NPN sensors produce a negative signal during an “on” state.

Which is faster NPN or PNP?

Mobility of electrons is more than hole, so as a result n-p-n transistors are faster than p-n-p that's why they are preferred.

Why NPN is used over PNP?

Thus n-p-n is preferred as in this electrons have higher mobility than holes, which results in high mobility of energy. In a p-n-p transistor, the positive supply line becomes a common point of input and output current, due to which the ground current is positive. This is inconvenient for design and maintenance.

Why do transistors have 3 legs?

The transistor has three legs, these are the base, collector and the emitter. The emitter is always connected to 0v and the electronics that is to be switch on is connected between the collector and the positive power supply. The base of the transistor is used to switch current through the collector and emitter.

Is NPN normally open?

NPN SENSORS: The sensor output is normally floating (open collector), therefore it can be considered virtually isolated and free of voltage. When active, the sensor output is brought to ground by the electronics inside the sensor itself.
