http://doumai.pagesperso-orange.fr/...Reflexe_Jeu.htm. That said, if we focus on the family, the differences between all members are quite slight. Merci de ne pas poster des messages en relation avec le piratage, Envoyer un lien vers cette page par email. The BC547 is an NPNBipolar Junction Transistor (BJT). These transistors are utilised in audio frequency, and small signal directly coupled preamplifiers. Google is a great tool, also for programming problems. collector terminal, base terminal and emitter terminal respectively. BC547 Transistor. Il voulait écrire 2N1711, ça ne rajeunit pas. Les transistors BC547 (et les autres de la gamme) ont un gain en courant (noté hfe) qui varie énormément d'un transistor à l'autre. equivalent transistor BC547. Imagine that you have designed the circuit to work with a minimum of 200hFE and you have a BC547B but you decide to replace it with a BC547A or BC547, it may not reach that rate and it may not work… If you make it to work with 110, either one will work. The complementary PNP transistor to the BC546 is the BC556. This will remind you something if you have studied topics like high pass and low pass frequencies, right? Franchement les BC 546,547,548 et le 2N2222A ce sont des transistors tres courants qui se vendent chez tous les vendeurs de composants meme chez les + demunis ou malheureux et ça coute rien entre 15 a 40 centimes d'euro. The name bipolar comes from the fact that they form 2 PN junctions, since transistors have three semiconductor layers arranged in two possible ways: NPN and PNP. Voici les gains des transistors : Similar to all the other transistors BC547 has also three terminals e.g. Introduction. [ 1] [ 2] pierre199. Once we know this, we will better understand how the BC transistor works. It consists of three terminals, these are emitter (E), collector(C), and base (B). If you are a maker, you like DIY and electronics, you have probably ever needed to use a BC547 transistor. That’s why we’re going to show some equivalencies or antagonists. Dans cette rubrique, j’ai mis en ligne un manuel qui nous est très utile, même indispensable : les équivalences des transistors. BC547 - 500mW. le BC547 est archi courant chez les épiciers. SMD Equivalent. Mike Darn, I can't post the images in the text, had to include them as attachments, sorry . If there is no such letter, then it could be any one within the range I have given. The differences between the series were basically the packages, being equal inside them. I hope this post helped you and the next one will be PN2222. The general-purpose range of transistors is a good substitute for basic non-critical audio applications, as these transistors are similar and equivalents to each other. BC547 is usually used for amplification and switching purposes. MOTOROLA Order this document SEMICONDUCTOR TECHNICAL DATA by BC546/D Amplifier Transistors BC546, B NPN Silicon BC547, A, B, C BC548, A, B, C COLLECTOR 1 2 BASE 3 EMITTER 1 MAXIMUM RA . This is a bipolar junction transistor that was originally developed by Philips and Mullard between 1963 and 1966. Here is an image showing the pin configuration of this transistor in case type TO-92. In most cases you could. After knowing some things in common with the family members, let’s focus on some magnitudes and characteristics specific to BC547. S8050.png 73.75 KB downloaded 1065 times BC547.png 124.9 KB downloaded 673 times Google is a great tool, … It consists of three terminals, these are emitter (E), collector(C), and base (B). These types of bipolar transistors are made from materials such as germanium, silicon or gallium arsenide. The SMD versions of the BC546 are available as the BC846 (SOT-23) and BC846W (SOT … Afficher une version imprimable. The gain of the BC547A will be in the range from 110 to 220, BC547B ranges from 200 to 450, BC547C ranges from 420 to 800. Complementary PNP transistor. The gain of the BC546A will be in the range from 110 to 220, BC546B ranges from 200 to 450, BC546C ranges from 420 to 800. In the case of BC548, like its family brothers, they have a very good gain of between 110 and 800 hFE for direct current. pierre199 ☆☆☆☆☆☆☆ 15/02/2012, 18h24 #1 bonjour, la question a sans doute déjà été posée mais je n'ai pas trouvé. [ I DO NOT respond to personal messages, I WILL delete them unread, use the forum please ]. BC547 is a general purpose BJT NPN transistor mostly used in electronics hobbyists and educational electronics projects. Là aussi, c'est un classique des transistors bipolaires. pour daudet78: désolé pour la faute de frappe c'est promis je recommencerai pas. And it was evolving from BC108, BC238, to what we know today as BC548 with a cheaper TO-92, package and from here the variants like BC547 emerged. For example: That is to say, the manufacturer estimates that it will be between those ranges, but it is not known exactly what the real gain is, so we must put ourselves in the worst case when we design the circuit. To identify them, we must look at them from the chamfered or flat face of the package, that is, leaving the rounded face for the other side. BC547 Transistor Equivalent Substitute - Cross-Reference Search BC547 Datasheet (PDF) 0.1. bc546 bc547 bc548.pdf Size:193K _motorola. Their specifications are not particularly exacting and a variety of general purpose transistors could be used. That way it is guaranteed that the circuit is functional even if the gain is the minimum of the range, and it is also guaranteed that the circuit will continue to work if we replace the transistor. The amount of current flowing from base to the emitter controls the amount of the current flowing through the collector. Its maximum current gain is around 800. Save my name, email, and website in this browser for the next time I comment. There are also other designations such as BF, but in this case it is used to identify transistors used for RF (radio frequency), that is, those that achieve good gains at very high frequencies. October 27, 2020 October 2, 2020 by James Smith. The BC549C is an NPN transistor belonging to a group of general-purpose NPN semiconductors consisting of BC547, BC548, and BC549. I will be able to buy BC547 but I will use the S8050 because I have it, Transistor as as switch - replace BC547 with S8050, Topic: Transistor as as switch - replace BC547 with S8050, Re: Transistor as as switch - replace BC547 with S8050, https://www.sparkfun.com/datasheets/Components/BC546.pdf, http://media.nkcelectronics.com/datasheet/s8050.pdf, Quote from: botzko on Dec 06, 2017, 06:11 pm. Tu mets n'importe quoi NPN.... sauf 1N1711 qui devrait être une diode. Unlike EC (Common Transmitter), which is the only one to achieve both voltage and current gains, and CC (Common Collector) very useful to adapt stages with very different impedances respectively.
