2n3904 transistor pinout

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.

What is the use of 2N3904 transistor?

The 2N3904 is an extremely popular NPN transistor that is used as a simple electronic switch or amplifier that can handle 200 mA (absolute maximum) and frequencies as high as 100 MHz when used as an amplifier.

Is BC547 same as 2N3904?

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

Is a 2N3904 a PNP transistor?

The 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. It is designed for low current and power, medium voltage, and can operate at moderately high speeds.

Which transistor can be used in place of 2N3904?

Given below is the list of popular transistors which can be used as a replacement for 2N3904: BC537, BC538, 2N4401, and P2N2222A. BC547 and BC548 are functionally equivalent transistors.

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.

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 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.

Why is HBT better than BJT?

In comparison with Si bipolar junction transistors (BJTs), HBTs show better performance in terms of emitter injection efficiency, base resistance, base-emitter capacitance, and cutoff frequency. They also offer good linearity, low phase noise and high power-added efficiency.

Can I use 2N3904 instead of BC548?

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

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.

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 you replace a PNP with a NPN transistor?

Answer: NPN and PNP transistors are interchangeable if you remember one simple rule: A bipolar transistor is essentially two back-to-back diodes with the base being the common connection.

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 know if I have NPN or PNP?

The schematic symbols for NPN and PNP transistors are extremely similar. The sole distinction is the orientation of the arrow on the emitter. It points outward in an NPN (on the left) and inward in a PNP (on the right).

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.

Are BJTs obsolete?

Yes, BJTs are still used. BJTs have higher transconductance, which gives them higher gain.

Which transistor is fastest?

Cerebras team leader Michael James and the Department of Energy's Dirk Van Essendelft said in their paper that the CS-1, powered by 1.2 trillion transistors, performed at 200 times the speed of a Joule supercomputer in a simulation of powerplant combustion processes.

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 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.
