I Transistor - isisekelo Semiconductor ubuchwepheshe

Transistor - ilungu okhulisa, isizukulwane, futhi yokuguqula oscillations kagesi. Transistors kukhona ezimbili zama: okuguquguqukayo futhi ensimini.

Transistor Bipolar - a idivayisi Semiconductor ehlanganisa kokuhlangana okubili PN. Transistor Elemental ukwakhiwa phezu crystal germanium, it has prongs ezimbili: i emitter futhi ngalendoda, ezihlobene ebusweni crystal, bathinteka komunye nomunye by ibanga 20-50 microns. Ngamanye amazwi, a yezinyawo uxhuma emitter base (ibizwa ngokuthi kwalapho emitter), kanti eyesibili - ngalendoda sizindza (ibizwa ngokuthi kwalapho ngalendoda). transistors Bipolar zihlukaniswe izinhlobo ezimbili: pnp futhi npn.

Inkambu umphumela Transistor - idivayisi Semiconductor, okuyinto ilawulwa ukushintshashintsha ensimini, ngokungafani kuya izakhi okuguquguqukayo, lapho wamanje okukhipha kunqunywa ngokushintsha zamanje input. amadivaysi Field kukhona odnozatvornymi futhi mnogozatvornymi.

Umdwebo wokuhlelwa kwendikimba Transistor kuboniswa esithombeni ngezansi. Isikimu isici okuguquguqukayo mfushane yomugqa isisekelo, limelela isizinda, lapho 60 ⁰ no-120 ⁰ kuhlanganisa imigqa emibili idayagonali, umugqa umcibisholo - kuyinto emitter, kwesibili - ngalendoda. isiqondiso umcibisholo kubonisa uhlobo lisebenze. Umcibisholo obheke ku-database - lokhu Transistor pnp uhlobo base - npn. Perpendicular base umugqa - a electrode isizinda. Inani conductivity kagesi of emitter odinga ukukwazi ukuze uxhume kahle Transistor amandla supply. Wensimbi pnp thayipha ngalendoda futhi base kuyadingeka ukunikezela negative voltage Transistor futhi npn uhlobo - omuhle. FETs kule imidwebo kuboniswe kanje: esangweni wenza isibonisi dash, uphawu isiteshi okufanayo, le conductivity wesiteshi emelelwa imicibisholo ibekwe phakathi omthombo abakhwabanisi. Uma amaphuzu umcibisholo isiqondiso siteshi, kusho ukuthi element kungokwalabo n-hlobo, futhi uma kolunye uhlangothi, ke p-hlobo. Image of a Transistor ensimini umphumela nge lokungeniswa isiteshi uhluke imivimbo emithathu emfushane. Uma idivayisi yasensimini amasango eziningana, sawo sokuphila esifushane odwi show, owokuqala esangweni umugqa njalo ibekwe ukwelulwa umugqa umthombo.

Ekuphetheni, siye sinezele ukuthi we transistors kungukuthi ngokushesha wanamathela igama, ekuqaleni wababiza Semiconductor triodes (efanayo tube ubuchwepheshe). Ngakho ukuthi Transistor - a Transistor, okuyinto liyisici luyalawuleka, it is kabanzi ukushintsha futhi yokukhulisa izwi izifunda. Ukuswelakala kokusebenza ngokuhlanganyela ukushuba, ukuthembeka, ezincane Ubukhulu kanye nezindleko - lawa izinzuzo main yalezi amadivaysi, ngenxa okuyinto transistors kuyo kungawisa emagatsheni amaningi amashubhu art cleaner. Inzuzo enkulu amadivayisi Semiconductor ukungabi cathode hot, okuyinto ngezikweletu amandla abalulekile, kanye azithathe isikhathi ukuxoxa. Ngaphezu kwalokho, Transistor incane kakhulu kunaleyo Isibani sikagesi futhi uyakwazi sokuqhuba voltage aphansi. Konke lokhu kuye bavunyelwe kakhulu ukunqinda amadivayisi ayi- elekhthroniki.
