Which transistor is equivalent to BC547?

BC547 Equivalents The BC series, such as BC549 and BC639, are the finest recommendations for the BC547 transistor equivalent, followed by the 2N2222 transistor. BC636 replaces BC547, 2N2369, 2N3055, 2N3904, 2N3906, and 2SC5200 in the PNP.

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.

What are the 3 pins of a transistor called?

In general, all transistors have three pins: base, collector, and emitter. Transistor is a bi-polar device that is a transistor with two junctions namely BE and CE DE EE FE.

What is C945 transistor used for?

C945 is usually used in electronic circuits where there is a need for a high-speed transistor and a low current. C-945 has three semiconductor regions named emitter, base, and collector respectively. When we apply voltage at C-945's base, the current starts to flow between collector and emitter.

What is A1015 transistor?

The A1015 transistor is a high voltage and high current PNP transistor. A transistor can normally be used as a switch or amplifier, but this transistor is commonly is used only for audio frequency amplifier application since it has a very high dc current gain value of 120-700.

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.

Why did mosfets replace BJTs?

There are many benefits of using MOSFET instead of BJT like the following. MOSFET is very responsive as compared with BJT because the majority of charge carriers in the MOSFET are the current. So this device activates very quickly as compared with BJT. Thus, this is mainly used for switching the power of SMPS.

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 It was originally made in the TO-18 metal can as shown in the picture.

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.

What is the BC547 transistor pinout?

The BC547 transistor pinout shows 3 pins from left: Collector, base, and emitter respectively. This pin act as an inlet as the current enters the transistor from here. The collector is denoted by 'C'. This pin controls the transistor biasing.

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).

Are BJTs faster than MOSFETs?

BJT can switch faster than MOSFET due to the less capacitance at the control pin. However MOSFET is more tolerant to heat (stable to thermal changes) and can simulate a good resistor." So, to answer your question, a "BJT can switch faster than MOSFET due to [there being] less capacitance at the control pin."

Are BJTs cheaper than MOSFETs?

Well, BJTs are not easily damaged by static electricity, they are cheaper and easier to bias than MOSFETs. BJT is the more robust candidate. They are a preferred option for low-current applications like switching a low-current relay, LEDs, and amplifiers.

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.

How do you tell which pin is which on a transistor?

The pin opposite the Emitter is the Collector, while the one in the middle is the Base. With the PNP transistor, the reverse is the case. The pin closest to the tab is the Collector, and the one opposite it is the Emitter, and the pin in the middle is the Base.

How do you test a 3 pin transistor?

Hook the positive lead from the multimeter to the to the EMITTER (E) of the transistor. Hook the negative meter lead to the BASE (B) of the transistor. For an good NPN transistor, you should see “OL” (Over Limit). If you are testing PNP transistor, the meter should show a voltage drop between 0.45V and 0.9V.
