BC547 transistor: zvese zvaunoda kuti uzive

Kana iwe uri mugadziri, iwe unofarira DIY nemagetsi, zvirokwazvo iwe wakamboda kushandisa a BC547 transistor. Iyo bipolar junction transistor iyo yakatanga kugadzirwa naPhilips naMullard pakati pa1963 na1966. Pakutanga yakatumidzwa zita rekuti BC108 uye yaive ne TO-18 mhando yesimbi encapsulation (Transistor Outline package - case style 18). Iyo package yaive inodhura zvakanyanya kupfuura epurasitiki yakaenzana TO-92, asi kupisa kupisa kuri nani mune yekutanga.

Gare gare yaizove nepurasitiki nyowani uye yakapihwa zita rekuti kodhi BC148. Uye zvakashanduka kubva BC108, BC238, kuenda kune izvo zvatinoziva iye zvino seBC548 ine encapsulation yakachipa mhando TO-92, uye kubva pano kwakauya akasiyana akadai seB547. Misiyano iripakati pezviteedzano yakanyatsovharirwa, ichiva yakafanana mukati. Uye zvakare, kune ayo chirevo BC Inotaridza kuti iri silicon transistor (B), yepasi frequency (C).

Kune mamwezve mazita akadai se iyo BF, asi mune ino kesi inoshandiswa kuzivisa ma transistor anoshandiswa kuRF (radio frequency), ndiko kuti, iwo anowana mibairo yakanaka pamatanho akakwirira kwazvo.

BC5xx kuongorora kwemhuri:

Iyo BC547 ndeyemhuri yeva transistors vane zvakafanana maitiro seiyo BC546, BC548, BC549 uye BC550. Iwo ese ari eiyo bipolar kana bipolar junction mhando (BJT yeBipolar Junction Transistor). Ndokunge, ivo havazi munda unochinja ma transistors senge maFET, mwenje-unodzorwa mafototransistori, nezvimwe. Aya marudzi e bipolar transistors akagadzirwa nezvinhu zvakaita segermanium, silicon kana gallium arsenide.

Zita re bipolar rinouya kubva pakuti ivo vanoumba 2 PN mharadzano, sezvo ma transistor ane matatu semiconductor akaturikidzana akarongwa munzira mbiri dzinogona: NPN uye PNP. Panyaya yeBC547 takatotaura kuti iri NPN. Ndokunge, semiconductor yakasungirirwa nechinhu chetafura ye periodic iyo inobvumidza kuti ive neyakawandisa yechaji vatakuri (maerekitironi) eN zvikamu, uye semiconductor yakasungirirwa nechinhu chine maerekitironi mashoma epa valence achipa P-mhando semiconductor. ine yakawandisa yeakanaka mutero vatakuri mune ino (maburi).

Izvo zvakati, kana isu tichifunga nezvemhuri, mutsauko uripakati penhengo dzese iri nyoro kwazvo. Iyo encapsulation yezvose yakafanana, iyo SOT54 kana TO-92. Asi yega yega yakagadziriswa kune yakasarudzika mhando yebasa:

• BC546: kune yakakwira voltage (inosvika 65v).
• BC547: zvakare yeakakwira voltage (45v)
• BC548: kune akajairwa voltages, anosvika makumi matatu.
• BC549: yakafanana neBc548 asi iine ruzha rudiki rwezvimwe zvinonyanya kunetsa maitiro kana inonzwika kune ruzha rwemagetsi. Semuenzaniso, hi-fi kurira masisitimu.
• BC550: yakafanana neyokutanga mbiri, ndiko kuti, kune yakakwira voltage (45v) asi yakagadziridzwa kupa yakaderera ruzha.

Ose ane mapini matatu, sezvazvinonzwisisika mune transistors. Kuti tizvizive, isu tinofanirwa kuzvitarisa kubva kune yakakwenenzverwa kana kumeso kumeso kweiyo encapsulation, ndiko kuti, kusiya chiso chakatenderedzwa kune rimwe divi. Nekudaro, kubva kuruboshwe kurudyi pini ndidzo: collector - base - emitter.

• Zvakawanda: ipini yesimbi kana pini inosangana nenzvimbo isina doped kupfuura emitter. Mune ino kesi inzvimbo yeN.
• hwaro: iyo pini kana simbi inobatana yakabatana nenzvimbo yepakati iyo inofanirwa kuve yakatetepa. Mune ino kesi inzvimbo P.
• Rinofambisa: iko kubatana kwakabatana kune mumwe mugumo (nzvimbo N mune iyi kesi) uye iyo inofanirwa kuve inzvimbo ine doped zvakanyanya kupa huwandu hukuru hwevatakuri kune azvino.

Kana izvi zvangozivikanwa, isu tinonzwisisa zvirinani mashandiro anoita transistor BC. Mune chaiyo kesi yeiyo BC5xx, zvinobuda mazaya e kusvika ku100 mA. Ndokunge, uku ndiko kuve kwakanyanya kusimba uko kunogona kuyerera pakati pemuteresi uye emitter, inodzorwa nechigadziko sekunge chiri switch. Panyaya yematambudziko akagamuchirwa, izvi zvinosiyana zvichienderana nemuenzaniso sezvataona.

Rangarira kuti iko kusimba kwazvino kusimba kwe100mA ndeye chete iyo DC, nekuti iyo yekuchinjika yazvino uko kune points peaks yenguva pfupi inogona kukwira kusvika ku200 mA isina kuparadza iyo transistor. Nekudaro, vamwe vagadziri senge yengano uye nhoroondo Fairchild vakatovaka BC547 mamodheru anokwanisa kusvika 500mA, kunyangwe isiri standard. Saka iwe unogona kuwana pamwe madhatashiti eiyo BC547 ane ma voltages angangochinja kune izvo zvataurwa pano

Zvimiro zveBC547:

Mushure mekudzidza nezvezvimwe zvinhu zvakafanana nenhengo dzemhuri, ngatitarisei pane mamwe makuru uye chaiwo maficha eiyo BC547.

Wana:

La kuwana ikozvino, kana tichitaura nezve base base, ingangove iyo yazvino kuwana kubva kune iyo emitter kuenda kune muunganidzi munzvimbo yakananga inoshanda, inogara iri pasi pe1. yepakati 110 uye 800 hFE yezvazvino uno. Izvi zvinowanzo rondedzerwa neimwe tsamba yekupedzisira kumagumo ezita rezita rinoratidza iro huwandu hwekuwana uchifunga kushivirira kwechigadzirwa. Kana pasina tsamba yakadai saka inogona kuve chero iri mukati mehurefu hwandakapa. Semuyenzaniso:

• BC547: pakati pe110-800hFE.
• BC547A: pakati pe110-220hFE.
• BC547B: pakati pe200-450hFE.
• BC547C: pakati pe450-800hFE.

Ndokunge, iye mugadziri anofungidzira kuti ichave iri pakati pematanho aya, asi hazvizivikanwe chaizvo kuti chaicho purofiti chii, saka tinofanira kuzviisa mukati nyaya yakaipisisa patinogadzira dunhu. Nenzira iyi, zvinovimbiswa kuti dunhu rinoshanda kunyangwe iko kuwana kuri kushoma kweiyo renji, pamwe nekuvimbisa kuti dunhu raizoramba richishanda kana tikatsiva transistor yakati. Fungidzira kuti iwe wakagadzira iyo dunhu kuti ishande neinosvika 200hFE uye iwe une BC547B asi funga kuitsiva ne BC547A kana BC547, inogona kusasvika mwero iwoyo uye haishande ... Kune rimwe divi, kana unozviita kuti ushande nevane zana, zvimwe zvinokushandira.

La frequency mhinduro zvakakosha zvakanyanya kune ma amplifaya. Kunyangwe zvichikwanisika kushanda neimwe kana mamwe mafrifits kunoenderana neyakawandisa mhinduro yeiyo transistor. Izvi zvinokuyeuchidza nezve chimwe chinhu kana iwe wakadzidza misoro senge frequency kukwira kupasa uye pasi paseti mafirita, handiti? Muchiitiko chemhuri inoonekwa pano, uye nekuda kweiyo BC547, ivo vane yakanaka frequency frequency mhinduro uye vanokwanisa kushanda pazviyero pakati 150 uye 300 Mhz.

Kazhinji, mu dhatabheti Yakazara ruzivo rweiyo transistor inopihwa kubva kune vanogadzira, kusanganisira girafu yeiyo frequency mhinduro. Aya magwaro anogona kutorwa pasi muPDF kubva kune epamutemo mawebhusaiti evagadziri vezvigadzirwa, uye ipapo uchawana iwo maitiro. Iwe uchaona kupindura kwakawanda nema initials fT.

Aya mafambiro akakurisa anozovimbisa kuti transistor gonesa kanenge 1, sezvo iko kukwirira kweiyo frequency, iko kudzikisa kukwidziridzwa kweiyo transistor nekuda kweiyo capacitive chikamu chayo. Pamusoro peaya mafambiro anogamuchirwa, iyo transistor inogona kunge iine yakaderera kwazvo kana kusawana pfuma, saka haina kubhadhara.

Kufanana uye kuzadzikiswa:

• Zvakaenzana:
  • Saizvozvowo: rakaenzana gomba bhodhi gomo transistor raizove iro 2N2222 kana PN2222 yatiri kuenda kunotsaurira imwe yakakosha chinyorwa. Asi chenjera! Muchiitiko cheiyo yenhema 2N2222, iyo emitter uye yekuunganidza pini inodzoserwa. Ndokunge, ichave emitter-base-muteresi panzvimbo ya collector-base-emitter. Naizvozvo, iwe unofanirwa kuiisa simbi kana kuiisa ichitenderedza 180 respect zvine chekuita nemabatiro awakaita BC547.
  • SMDKana iwe uchida nzvimbo yepamusoro yakaenzana neBC547 yemadiki madiki maseketi akadhindwa kana maPCB, saka izvo zvauri kutsvaga ndeye BC487 yakavharirwa pasi peSOT23. Izvo zvinodzivirira kuve neplate ine maburi ekumisikidza uye kugadzira. Nenzira, kana iwe uchitsvaga akaenzana bipolar transistors enedzimwe nhengo dzemhuri, unogona kutarisa iyo BC846, BC848, BC849 uye BC850. Ndokunge, chinja BC4xx neiyo yakaenzana BC8xx.
• Inowirirana: Imwe mamiriro ezvinhu anogona kuitika ndeyekuti iwe unoda zvakapesana, ndiko kuti, PNP panzvimbo yeNPN. Panguva iyoyo, iyo chaiyo ichave iyo BC557. Kutsvaga zvinowaniswa zvevamwe vemumhuri, unogona kushandisa BC5xx senge: BC556, BC558, BC559 uye BC560.
