Is 2N3904 transistor NPN or PNP?

Is 2N3904 transistor NPN or PNP?

NPN transistor
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 is the difference between 2N3904 and 2N4401?

As you say, the 4401 and 3904 have similar specs, but there are differences. The 3904 is better at really low currents, but the 4401 can handle higher currents. Most of the time the 4401 is good enough, so I “standardized” on it since it’s more robust and I run into 100 mA applications more than 100 µA applications.

Is 2N3904 a NPN transistor Why?

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.

Is 2N2222 the same as 2N3904?

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 we use BC548 instead of BC547?

BC547 and BC548 are basically the same, but BC547 has more breakdown voltage, while BC548 features low noise. They are the most general-purpose NPN silicon transistors, and switching one to the other will not significantly affect the circuit.

Can the BC547 transistor be used in place of the 2N3904 transistor?

The BC547 transistor can be used in place of the 2N3904 transistor, however, there are some conditions that must be met before utilizing it instead of the 2N3904. The collector current differential between the two transistors is the most important factor to consider.

What can be used instead of BC547?

BC547 can be replaced by BC548, BC549, 2N2222, 2N3904, 2N4401, and BC337 are equivalent to BC547. Can Use 2N3904 Instead of BC547?

What is the difference between 2N3904 and 2sc5200?

The first pin on the 2N3904 is Emitter, the second is Base, and the third is Collector, whereas the first pin on the BC547 is Collector, the second is Base, and the third is Emitter. BC548, BC547, BC636, BC639, 2N2222A, 2N2222, 2N2369, 2N3055, 2N3906, 2SC5200 are equivalent to 2N3904.
