2n2907

The 2N2907 is a commonly available PNP bipolar junction transistor 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.

What is the difference between PNP and NPN transistor?

PNP switches ON by a low signal whereas NPN switches ON by a high signal. In PNP transistors, the P represents the polarity of the emitter terminal and N represents the polarity of the base terminal. In NPN, N represents the negatively charged coating of the material whereas P represents the positively charged layer.

What is BC557 transistor?

BC557 is a general-purpose transistor, used like an amplifier or a switch in electronic circuits. Its hFE ratings of this transistor range from 125 to 800 to make the transistor ideal by using like an amplifier within electronic circuits like audio signal amplification.

What is TIP41C transistor?

The TIP41C is a base island technology NPN. power transistor in TO-220 plastic package that. make this device suitable for audio, power linear. and switching applications.

Why are BJTs still used?

Basic Applications of BJTs Though the original technology is itself almost 70 years old, bipolar transistors are still widely used to amplify and switch signals. In digital circuitry, they're used to amplify radio frequencies and switch heavy currents.

Why PNP is better than NPN?

As they are normally referred, PNP and NPN sensors are both supplied with positive and negative power leads, then produce a signal to indicate an “on” state. PNP sensors produce a positive output to your industrial controls input, while NPN sensors produce a negative signal during an “on” state.

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.

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.

What can I use instead of BC557?

Replacement and Equivalent: Alternative transistors for BC557 are 2N3906, 2N4403, BC556, BC327 output pins of some equivalents are different please see pinout details of the equivalent transistor before replacing in the circuit.

Can I use BC547 instead of BC557?

Can I use BC557 instead of BC547? Yes. You can use BC557 in place of BC547.

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.

Is TIP41C a Mosfet?

TIP41C MOSFET Datasheet pdf - N-Channel MOSFET.

Is TIP41C NPN or PNP?

Kartex Transistor - TIP41C NPN Transistor (Number of Transistors 1) Safe and Secure Payments. Easy returns. 100% Authentic products.

What can I use instead of a TIP41C?

Replacement and Equivalent The replacement and equivalents for TIP41C transistor are 2SD1895, MJE5180, MJE5181, BD711, BC911.

Why are BJTs better than MOSFETs?

The advantages of BJT over MOSFET include the following. BJTs have higher fidelity & better gain in the linear areas as evaluated with the MOSFETs. As compared with MOSFETS, BJTS are very faster because of the low capacitance on the control pin. But MOSFET is more tolerant to heat & can simulate a good resistor.

Are BJTs outdated?

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

Why MOSFET is preferred over BJT?

BJTs have switching frequencies of up to hundreds of kHz, while MOSFETs can easily switch devices in the MHz range. So, for high-frequency applications where switching losses have a major role in the total power loss, MOSFET is preferred.

Is NPN sink or source?

NPN transistor outputs are called “sinking outputs” because they sink current from the load into the output.

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.

Are Mosfet NPN or PNP?

An N-Channel mosfet needs a positive Gate - Source voltage to conduct. An P-Channel mosfet needs a negative Gate - Source voltage to conduct. An NPN transistor needs a positive Base - Emitter current to conduct. An PNP transistor needs a negative Base - Emitter current to conduct.
