2N2222 transistor: yonke into ekufuneka uyazi

El 2N2222 okanye i-PN2222 transistor Yenye yezona zinto zisetyenziswayo kunye ne-BC548. Ke ngoko, ukuba uyayithanda i-DIY kwaye ungumenzi, ngokuqinisekileyo ngaxa lithile uye wafuna enye yezi zixhobo. Kule meko, i-PN2222 sisixhobo esiphantsi se-silicon transistor kwaye siyilelwe ukukhulisa umgca kunye nokusetyenziswa kwezicelo.

Isizathu sokuba ifunwa kangaka kukuba kulungile ekwandiseni imisinga emincinci kunye neethamo ezincinci okanye eziphakathi, ukongeza ekubeni ukwazi ukusebenza ngokuhamba rhoqo okuphakathi. Oko kuthetha ukuba ine ukusetyenziswa gabalala kwaye ithandwa kakhulu oonomathotholo. Abo bangabo baya kwazi ukuba yenye yeetransistors ezisetyenziselwa ukwakhiwa kwe-BITX transceiver, okanye ukuba yavumela iklabhu kanomathotholo iNorcal ham ngo-1999 ukuba iphumeze umceli mngeni wokwakha i-radio transceiver enama-22 kuphela abaguquli balolu hlobo ngaphandle kwayo uhlobo lwe-IC eyongezelelweyo.

Njengo-BC548, yenziwa kusetyenziswa iinkqubo zeepitaxy. Ikwayi-transistor Uhlobo lwebipolar kunye ne-NPN. Okwangoku ihlala ineepakeji ezininzi ezinokwenzeka, ezinje ngeplastiki TO-92, edla ngokuba yeyona ndlela iqhelekileyo yokuyivelisa kunye nezinye ezinje nge TO-18, SOT-23, SOT-223, njl.

Yintoni kanye le transistor?

Ukususela irediyo okanye i-transistor yabizwa njalo ngenxa yesi sixhobo sithethe ngaso, ndingathanda ukwenza intshayelelo emfutshane malunga nokuba yintoni i-transistor kunye nembali. Abaguquleli abekho ngaphezu kwezixhobo ezifana nokutshintshwa kunye nokukwazi ukwandisa umqondiso. Oko kukuthi, zizinto ezithatha indawo yeetyhubhu zokuthambisa zangaphambili okanye iivelufa zokucoca ezanika iingxaki ezininzi.

Ezi zivalo bezifana neebhalbhu zesintu, ke zinokuvuthuza kwaye kufuneka zitshintshwe rhoqo. Zazinkulu ngobukhulu kwaye zazingavumeli ukwenziwa kwezixhobo ezincinci. Ubushushu ababenzileyo yayiyenye ingxaki. Ngokufika kwe imeko zombane eziqinileyoOko kukuthi, ye semiconductors, ivumele ukwenziwa kolu hlobo lwezixhobo zitshiphu, zincinci kwaye zithembekile.

Igama le-transistor livela kumanyano we ukudlulisa kunye nokumelanaOko kukuthi, ukudluliselwa kokuchasana ngesiNgesi. Khumbula ukuba ukuxhathisa kukuxhathisa. Ukongeza, njengoko usazi, uyilo lwavela eYurophu kunye nelungelo lokuqala lobunikazi be-physicist uLilienfeld (1925). Kwakungaphambi kwexesha layo, kuba abafumananga zicelo zisetyenziswayo kule minyaka ilishumi okanye elandelayo, kwaye yayiyimpembelelo yentsimi, ingcinga ethe kratya nangaphezulu kunee-bipolar.

U-Oskar Heil wenza isixhobo esifanayo eJamani ngo-1934, emva koko uRobert Pohl no-Rudolf Hilsch nabo bazakwenza imifuniselo enxulumene nolu hlobo lwesixhobo kwiyunivesithi yaseJamani. Ngendlela ephantse yafana, eUnited States kwi Iilebhu zeBell ze-AT & T Uvavanyo olungaphumelelanga belusenziwa, de kwasemva kokuba iMfazwe yesibini (II) yeHlabathi itshintshile kubo kwaye xa bebuya emfazweni eYurophu beza nesisombululo ngokuza nezimvo "ezihlaziyiweyo".

UJohn Bardeen, uWlater Brattain kunye noWilliam Shockley Bathathe ikhredithi ngokunikezela ngelungelo lokushicilela kwi-transistor yokuqala kwimbali kunye nokuphumelela amabhaso eNobel. Ngomnyaka we-1948 baqulunqa i-transistor yoqhakamshelwano, isixhobo esikhulu kakhulu, esingcolileyo nesingenakwenzeka esabiza kakhulu ukwenza kwaye ngamanye amaxesha sasilela kwaye kwafuneka sibekwe kwezinye iimeko. Ukusuka apho baya kuguquka baye kwi-transistors yangoku.

Kodwa ukuba uyafuna ukwazi indlela esebenza ngayo ngokuchanekileyo esi sixhobo Uhlaziyo lwe-elektroniki kunye nehlabathi lobuchwepheshe, Nantsi le GIF enomfanekiso malunga ne-transistor kunye nenkqubo ye-hydraulic, endicinga ukuba awuyi kuyifumana ibhetele kunalo mzekelo wokubamba umbono wokuba isebenza njani i-transistor:

Kuyabonakala ukuba xa umbane unikezelwa kwisiseko se-NPN transistor okwangoku kudlula kumqokeleli uye kwi-emitter. Kodwa iyakhula, kuba ukuba ujonga umfanekiso, umsinga wamanzi osisiseko kunye nomqokeleli uyongezwa. Yi isifaniso ilula kakhulu, nangona inkqubo ye-elektroniki kufuneka ubeke endaweni yamanzi ngee-elektroni ...

Ukuba ufuna ukubona umfanekiso okhanyisayo ngakumbi ukusuka kwindawo yokujonga ukusebenza kwemimandla ye-semiconductor, oko kukuthi, abathwali bemithwalo, nanku omnye umfanekiso:

Emfanekisweni uyabona ukuba xa kusetyenziswa umbane ongalunganga kwi-emitter, ityhala iarriers carriers (electron) kwaye kwisiseko izithuthi ezihlawulisayo (imingxunya) "yifunxa" ii-electron ukuze bakwazi ukutsiba kumqokeleli...

Kwimeko ye PNP Kuya kufana, kodwa tshintsha iipolarization okanye iindlela zokudibanisa i-transistor.

2n2222 Iimpawu:

I-2N2222 okanye i-PN2222 ihlala ihleli yenziwe nguPhilips Semiconductor, nangona sinokufumana abanye abavelisi abanjengoMbali weSemiconductor wembali, i-Nokia yaseJamani, i-COMSET Semiconductor, iSEMICOA, njl. Une Umahluko ogama linguN2A.

I-2N2222A yile ezifakwe ngaphakathi kuhlobo lwesinyithi TO-18 kwaye ikulungele ukusetyenziswa kwizicelo zomkhosi (MIL-STD) ngenxa yomelela kwayo, uluhlu lobushushu olwamkelekileyo, njl. Ukuba sijonga iidathasheets ezibonelelwe ngala malaphu, iimpawu esiza kuzifumana kule transistor zezi:

I-JZK-Iseti ye-Assortment ye...
