Le transistor - isiseko technology semiconductor

Transistor - ilungu okhulisa, isizukulwana, kananjalo lokuguqula oscillations zombane. Transistors ezi ndidi mbini: disorder entsimini.

transistor vuvabyi - a isixhobo semiconductor ezibandakanya ezimbini PN ezidibanayo. transistor elemental yakhiwe kwi crystal germanium, iye prongs ezimbini: i emitter nombuthi, ezinxulumene yikristale kumphezulu, nabanye omnye komnye yi kumgama 20-50 microns. Ngamanye amazwi, indledlana inxulumanisa emitter kwi siseko (oko kubizwa ngokuba isiphambuka emitter), kwaye eyesibini - sokuqokelela kunye nesiseko (ibizwa i isiphambuka umqokeleli). transistors Bipolar zahlulwe iintlobo ezimbini: PNP kunye npn.

Isiphumo ifildi transistor - isixhobo semiconductor, nelawulwa yi-cinci ku fana entsimini, xa kuthelekiswa izinto eguquguqukayo, apho imveliso yangoku kumiselwa ngokuguqula igalelo yangoku. izixhobo endle odnozatvornymi kunye mnogozatvornymi.

Idayagram ebonisa transistor kuboniswe kulo mfanekiso ungezantsi. Scheme element vuvabyi yi isiseko-line mfutshane, limela isiseko, apho kwi 60 ⁰ no-120 ⁰ iquka imigca emibini oxwesileyo, umgca ngotolo - yinto emitter, okwesibini - sokuqokelela. kwicala utolo ibonisa uhlobo sixhobo. Utolo olalathe kwiziko ledatha - eli transistor PNP hlobo kwisiseko - npn. Aa Incopho kumgca lesakhelo - i electrode kwisiseko. Ixabiso lombane lwe emitter kufuneka ukwazi ukuqhagamshela kakuhle transistor ukuya umbane. Isixhobo PNP chwetheza sokuqokelela kunye nesiseko kuyimfuneko ukuba unikeze elibi transistor ombane kunye npn uhlobo - HIV. FETs kwi imizobo zibhalwe ngolu hlobo lulandelayo: isango wenza umboniso dash, isimboli channel ngaxeshanye, conductivity umjelo amelwe iintolo ibekwe phakathi umthombo kunye idreyini. Ukuba amanqaku utolo kwicala umjelo, oko kuthetha ukuba element bobabo n-type, ukuba kwelinye icala, ngoko ke p-uhlobo. Umfanekiso we transistor isiphumo entsimini kunye yoqheliso channel eyahlukileyo imivumbo emithathu emifutshanana ngeveki. Ukuba isixhobo unomthamo amasango eziliqela, yabo emfutshane oodwi bonisa, umgca isango lokuqala usoloko kubekwa phezu ukwandiswa kumgca lomthombo.

Xa ndiqukumbela, senza ukuba le transistors azikho nangoko wanamathela igama, ekuqaleni wazibiza triodes semiconductor (technology tube efanayo). Sothi transistor - a transistor, leyo yinto efunekayo controllable, lisetyenziswa xa isenza i yaye zwi neziphaluka. Ukungabikho ubunzulu, ukuthembeka, ezincinane imilinganiselo kunye neendleko - ezi iingenelo eziphambili zezi zixhobo, ngenxa apho transistors ukuba kkuba ukusuka amasebe ezininzi kwimibhobho cleaner art. Inzuzo ephambili kwezixhobo semiconductor kukunqongophala cathode eshushu, nto leyo edla ngegunya, kwakunye ixesha athatha ukuncokola nabo. Ukongeza, i-transistor kuba ngaphantsi kakhulu isibane sombane yaye uyakwazi isebenze ombane asezantsi. Konke oku kuye ukuba nciphisa ngokubaluleka ubungakanani bezixhobo zombane.
