2n3904 pinout

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.

Is a 2N2222 the same as a 2N3904?

As described, the 2N3904 and the 2N2222 are both identical in the amount of voltage they can handle across the collector-to-emitter terminals- both can handle up to 40V. The 2N2222 differs in that it can handle a higher operating collector current.

Is BC547 same as 2N3904?

The equivalent for 2N3904: BC548, BC547, BC636, BC639, 2N2222A, 2N2222, 2N2369, 2N3055, 2N3906, 2SC5200 are equivalent to 2N3904.

What is the standard pin assignment of 2N3904?

2N3904 pinout has three pins: emitter, base, and collector respectively from left to right(flat side with the leads pointed downward).

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.

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.

Are all 2N3904 the same?

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.

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.

What is the difference between 2N3904 and 2N4401?

2N3904 and 2N4401 appear to be very comparable parts in all specs. 2N4401 has a higher current rating, but otherwise they look to be about the same in price and everything else. Obviously it's difficult to give a 100% universal answer since both parts are made by multiple manufacturers.

Can I replace BC547 with 2N2222?

The BC547 and 2N2222 transistors are both bipolar NPN transistors. The 2N2222 and BC547 transistors are both general-purpose transistors that are frequently used in electrical circuits; the BC547 transistor is one of the best transistor equivalents for the 2N2222 transistor.

Can I use 2N3904 instead of BC548?

EDIT: The 548 is 100mA, 30V. The 3904 is 200mA, 40V. So compatible within the specs.

Why is 2N3904 a NPN transistor?

2N3904 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. 2N3904 has a gain value of 300; this value determines the amplification capacity of the transistor.

How do I use 2N3904 as a switch?

2N3904 Transistor as a switch. In normal state, 2N3904 acts as reverse biased and there's no conduction between Collector & Emitter. When small voltage applies at its Base Terminal(normally 5V), 2N3904 converts its state from reverse to forward biased and conventional current starts flowing from Collector to Emitter.

What is the early voltage of 2N3904?

Emitter-Base Voltage Vebo of 2N3904 is 6V.

How does 2N3904 NPN transistor work?

What is B and C in BC547?

The semiconductor device like a transistor is one kind of switch which controls electrically. It consists of three terminals like an i/p, o/p & a control line. These are named as the emitter (E), collector(C) and base (B).

Why BC547 transistor is 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.

Why 2N2222 transistor is used?

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.
