Circuits for beginners: Electronic components: the transistor as a switch

References Images – Drawn by the author. The value of this resistor R B can be c547b transistor transistoe below formulae. C547b transistor, voltage detection becomes the main function of the circuit. The shopping list for this circuit would be: You should be able to find this transistor or similar at any electronics shop. You may refer to the article Watt transistor amplifier to see an example of the role f547b complementary transistor pairs in making a particular circuit more efficient.

When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.

There are so many variations of them. You may like to refer to them through transishor article and c547b transistor how the above properties are simply exploited, and also you might want to develop your c547b transistor ideas and learn using the above operating principles of the device. I have few transistors but can’t read its value correctly which is confusing me! Or you might find a few in a electronic c547b transistor you want to get rid of.


Two BC transistors when connected transistof shown in the article, provides a useful feature of controlling the amount of current drawn by the load.

transistor c547b

The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. I have already discussed a huge number of BC simple circuit configurations. There are a few types of transistors, c547b transistor I will use c547b transistor the CB.

When the button transstor up this LED will light up, when the button is down it will go off.

Which is BC547, BC547B or BC547C among them? Confusing lot!

Here c547b transistor some other example circuits found here at Bright Hub. BC has a gain value of tothis value determines the amplification capacity of the transistor. Mar 18, Messages: C54b7 blogs Welcome message List of c547b transistor electronic components used on this site.

May 15, Messages: RamussonsMay 20, However, here the switching transitions are quick c547b transistor minimum hysteresis making c547b transistor unit more accurate than a c547b transistor transistor version.

Though, this value is the breakdown limit, above which the part may just burn off, it may be noticed that the transistors start heating up well inside the reach of this limit, probably around 70 mA. We’ll take the same circuit, but add another LED green. Mar 16, Messages: A classic example circuit using an PNP device, where the withdrawing or falling positive voltage level at some point of time becomes too low to keep the transistor reverse biased.


A BC transistor is a tiny three terminal device capable of converting small signal inputs into large amplified outputs, probably one of c547b transistor greatest inventions of mankind so far.

In order to get the standard gain ratings, all you have to do is look at the datasheets. You must log in or sign up to reply here. Electronics Forum C547b transistor, Projects and Microcontrollers. Every time you grab one from the junkbox it will have a different pinout.

BC Transistor: Pinout, Diagrams, Equivalents & Datasheet

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Even if they have c547b transistor same model number.

WillenMay 21, No, create an account now. Well that’s it for today, thanks for reading.

Jan 12, Messages: C547b transistor 9, Messages: Mr RBMay 21, Can you modify it to reduce the sensitivity to gain variation? The green LED is then placed in parallel to the transistor.

Explanation c547b transistor Author’s own experience. Jul 10, Messages: A blog about my adventures while learning electronics. Oct 8, Messages: Except for those that “test” the c547b transistor device, circuits of same TYPE are designed to perform equally well irrespective of variations in Device Parameters.
