BC107 has a gain value hfe of 50; this value determines the amplification capacity of the transistor.

What is BC107 transistor?

The BC107 and BC107B are silicon planar epitaxial NPN transistors in TO-18 metal case. They are suitable for use in driver stages, low noise input stages and signal processing circuits of television receivers.

What is the difference between BC107 and BC547?

It looks like the BC547 is a modern replacement for the BC107. They are packaged differently but otherwise look very similar in terms of electrical characteristics. They seem to have the same breakdown voltage; the BC547 seems to have slightly better cutoff frequency. The current gain has a very similar range.

What is beta value for BC107?

between 110 and 450

Beta Value
One final point about Beta. Transistors of the same type and part number will have large variations in their Beta value. For example, the BC107 NPN Bipolar transistor has a DC current gain Beta value of between 110 and 450 (data sheet value).

How will you identify the terminals of bc107?

It is mainly composed of three terminals named as an emitter, base, and collector. Being a current controlled device, small current at the base side is used to control large current at the emitter and collector side.

What is the range of beta for the transistor?

between 50 – 200
The values of Beta vary from about 20 for high current power transistors to well over 1000 for high frequency low power type bipolar transistors. The value of Beta for most standard NPN transistors can be found in the manufactures datasheets but generally range between 50 – 200.

What is indicated by BC and 107 in bc107?

B- stands for Silicon Transistor C for- Audio Frequency Range. 107 – — Simple home/ experiment use.

Which transistor can I use instead of BC547?

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. 2N3904, BC547, BC548, and 2N3906 are 2N2222 comparable transistors.

Can I use BC548 instead of BC547?

What is the difference between BC547 and BC548? 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.

What is B and C in bc107?

The First letter indicates the construction-material. B for Silicon and C for germanium.

What is β for a CE configuration?

Beta is the transistors forward current gain in the common emitter configuration. Beta has no units as it is a fixed ratio of the two currents, Ic and Ib so a small change in the Base current will cause a large change in the Collector current. Was this answer helpful?

What is B and C in BC107?

What is indicated by BC and 107 in BC107?

What is current gain of transistor?

The current gain for transistor working as a common – base amplifier is 0.96 .

What is DC current gain in transistor?

BJTs are used to amplify current, using a small base current to control a large current between the collector and the emitter. This amplification is so important that one of the most noted parameters of transistors is the dc current gain, β (or hFE), which is the ratio of collector current to base current: IC = β*IB.

What does C indicate in transistor BC 547?

The BC547 transistor includes three pins which include the following. Pin1 (Collector): This pin is denoted with symbol ‘C’ and the flow of current will be through the collector terminal.

How do you identify BC107 terminals?

It is mainly composed of three terminals named as an emitter, base, and collector.

Circuit Diagram of BC107

  1. Emitter current is equal to the sum of collector and base current.
  2. The ability of base current to control large emitter and the collector current is used for amplification purpose.

Why BC547 transistor is 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.

Can I replace BC547 with 2N2222?

Can we use BC547 instead of 2N2222? Yes, you can use, for switching just look for Ic(collector current) and Vceo(collector-emitter voltage) in the datasheet.

Can I use 2N2222 instead of BC547?

BC547 vs 2N2222 Interchangeability
The 2N2222 has an emitter, base, and collector pinout, whereas the BC547 has a collector, base, and emitter pinout. The collector to base voltage at 2N2222 is 60 volts, whereas it is 50 volts at BC547, and the collector to emitter voltage is 30 volts at 2N2222 vs 45 volts at BC547.

What does C indicate in transistor BC548?

In the BC548 and BC547 transistors, the name B letter indicates that silicon material is used to build the transistor and the C letter indicates that, it is a transistor that handles low power audio frequency. They both are NPN transistors which are known as through-hole type and (TO-92 package) externally.

What is the relation between α and β?

β=1−α

What is the formula for current gain?

Current gain is the ratio of the change in the collector current to the change in the emitter current in a transistor. Mathematically α=△Ic△Ie.

What is the current gain formula?

The current gain of the transistor is 0.99, and the change in the emitter current is 5 mA. Current gain is the ratio of the change in the collector current to the change in the emitter current in a transistor. Mathematically α=△Ic△Ie.

How do you convert current gain to dB?

So if a circuit or system has a gain of say 5 (7dB), and it is increased by 26%, then the new power ratio of the circuit will be: 5*1.26 = 6.3, so 10log10(6.3) = 8dB.
Decibel Table of Gains.

dB Value Power Ratio 10log(A) Voltage/Current Ratio 20log(A)
0dB 1 1
1dB 1.26 1.1
3dB 2 √2 = 1.414
