Transistor 3904

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.

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.

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.

Is TIP122 NPN or PNP?

The TIP122 is a Darlington NPN transistor and it is very popular for its high current gain & high current.

Is 3904 NPN or PNP?

The 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications.

Can I use BC548 instead of 2N2222?

They are the same and are used interchangeably most of the time. 2N2222 is a metallic package TO-18 and PN2222 is a plastic package TO-92, you can refer to the datasheet of them. Can I use BC548 instead of BC547? NO, BC547 is an NPN and BC548 is a PNP transistor both the transistors are not substituted for each other.

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.

Is my transistor 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).

Can I use 2N2222 instead of BC547?

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.

How much current can a 2N2222 handle?

Typically, a 2N2222 transistor is able to switch 800 mA of load current through it, which may be considered quite high compared to the miniature size owned by these devices. High current switching capability also makes this device ideally suited for linear amplifier applications.

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 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.

Why we use NPN instead of PNP?

The mobility of electrons is better than the mobility of holes. 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.

What does N stand for in NPN?

NPN stands for Negative, Positive, Negative. Also known as sinking. On an IO Module, an NPN input, when undriven is pulled down to be in a low state, GND ( or reference voltage level e.g. V-). PNP stands for Positive, Negative, Positive.

Is TIP122 a Mosfet?

The TIP122 is a Darlington pair NPN transistor. It functions like a normal NPN transistor, but since it has a Darlington pair inside it has a good collector current rating of about 5A and a gain of about 1000. It can also withstand about 100V across its collector- Emitter hence can be used to drive heavy loads.

Can you wire PNP to NPN?

You cannot mix PNP and NPN sensors on the same common point for inputs to the PLC. If you do mix the sensors, then the different common points on the PLC must be isolated from each other.

What is NPN and PNP difference?

PNP switches On by a low signal whereas NPN switches ON by a high signal. As we are aware that in PNP transistor, the P represents the polarity of the emitter terminal and N represents the polarity of the base terminal.

Can I use any NPN transistor?

You can use any NPN type transistor (for example 2N3904, BC547, BC548, BC549 etc.) These are basic circuits, so they can be improved (with diodes for reverse voltage protection, for example), or can be simplified (XOR, XNOR gates), but for start we will stick with these basic circuits.

Can I use C945 instead of 2N2222?

As far as specs are concerned the C945 has more gain, Hfe, than the 2N2222, but for most applications yes you could use C945 in place of the 2N2222. One issue though is C945 has different pin out than the 2N2222. The 2N2222 base has pin out of emitter-base-collector (base is center pin).
