BC Transistor: Pinout, Diagrams, Equivalents & Datasheet

Please read them- ”. To participate you need to register. Q1 is the gain-critical transistor in that circuit. Top menu About Us Advertise.

Started by Silverboy Today at 7: Of the above types common emitter type is the popular and mostly used c5547b. It can amplify power, voltage and current at different configurations. Even different transistors with the same type number will have a range of hfe values. Nieuwere post Oudere post Homepage.

Welcome to our site! Hola RB, Talking about standards, is that new modern standard really c5477b as standards were expected to be and never were? Every single transistor has hransistor different gain. I think ” has large range of hFE to but ‘B’ or ‘C’ has small range of hFE like to or to Well that’s it for today, thanks for reading.


Willen Well-Known Member May 20, Mistakely I wrote ! A BC transistor has an hFE from to The resistor Electronic components: There is no such thing as a “different type of TO packaging case”. OpAmp circuit for temp sensing using trasistor Started by Elerion Today at 1: The value of this resistor R B can be calculated using below formulae.

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

Started by sr Today at 5: Building a light meter 1 Circuit basics: I have few transistors but can’t read its value correctly which is confusing me! When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Ttransistor and the Base Emitter voltage could be around mV. Except for those that “test” the semiconductor device, circuits of same TYPE are designed to perform equally well irrespective of variations in Device Parameters.

We’ll take the same circuit, but add another LED green. BC5xx are terrible for pinouts. Click here to register now. This site uses cookies c547 help personalise content, tailor your experience and to keep you logged in trannsistor you register. You must log in or register to reply tarnsistor.

BC trznsistor a NPN transistor hence the collector and emitter will be left open Reverse biased when the base pin is held at ground and will be closed Forward biased when a signal is provided to base pin.


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. The BC are also available with selected groups of current gain but it is marked “” for an average gain of”” for an average gain of and ‘” for an average gain of at mA.

These also have the new standard pinout. It’s better to buy bags of in more modern transistors.

Media New media New comments Search media. If I replaced 1st transistor with 2nd or 3rd one, the circuit might be fail.

You should be able to find this transistor or similar at any electronics shop. Willen Well-Known Member May 22, Gepost door Bart op I know these all transistors has different hFE: Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.


I have no idea what you’re asking. By continuing to use this site, you are consenting to our use of cookies. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.
