BFS481H6327 mabwalo ophatikizika Magawo Amakono / Kasamalidwe ka Analogi Ochulukitsa Ogawa

Makhalidwe a Zamalonda

Zachilengedwe & Zogulitsa kunja

Transistor ndi chipangizo cha semiconductor chomwe chimagwiritsidwa ntchito kwambiri mu amplifiers kapena masiwichi oyendetsedwa ndimagetsi.Transistors ndiye midadada yomangira yomwe imayang'anira magwiridwe antchito a makompyuta, mafoni am'manja, ndi mabwalo ena onse amakono amagetsi.

Chifukwa cha liwiro lawo loyankha mwachangu komanso kulondola kwambiri, ma transistors atha kugwiritsidwa ntchito pazinthu zosiyanasiyana zama digito ndi analogi, kuphatikiza kukulitsa, kusintha, kuwongolera ma voltage, kusinthasintha kwa siginecha ndi oscillator.Ma transistors amatha kupakidwa payekhapayekha kapena m'dera laling'ono kwambiri lomwe limatha kukhala ndi ma transistors 100 miliyoni kapena kupitilira apo ngati gawo lophatikizika.

Poyerekeza ndi chubu la electron, transistor ili ndi ubwino wambiri:

Chigawo chilibe chakudya

Ziribe kanthu momwe chubu liri labwino bwanji, pang'onopang'ono lidzawonongeka chifukwa cha kusintha kwa maatomu a cathode ndi kutuluka kwa mpweya kosalekeza.Pazifukwa zaukadaulo, ma transistors anali ndi vuto lomwelo pomwe amapangidwa koyamba.Ndi kupita patsogolo kwazinthu komanso kuwongolera mbali zambiri, ma transistors nthawi zambiri amakhala nthawi 100 mpaka 1,000 kuposa machubu amagetsi.

Idyani mphamvu zochepa kwambiri

Ndi gawo limodzi la khumi kapena khumi la imodzi mwa chubu cha elekitironi.Sichifunika kutentha filament kuti apange ma elekitironi aulere monga chubu la electron.Wailesi ya transistor imangofunika mabatire owuma ochepa kuti amvetsere kwa miyezi isanu ndi umodzi pachaka, zomwe zimakhala zovuta kuchita pawailesi ya chubu.

Palibe chifukwa chotenthetsera

Gwirani ntchito mukangoyatsa.Mwachitsanzo, wailesi ya transistor imazima itangoyatsidwa, ndipo wailesi yakanema ya transistor imakhazikitsa chithunzithunzi ikangoyatsidwa.Zida zamachubu owumitsa sizingachite izi.Pambuyo pa boot, dikirani kwa kanthawi kuti mumve phokoso, onani chithunzicho.Mwachiwonekere, mu usilikali, muyeso, kujambula, ndi zina zotero, ma transistors ndi opindulitsa kwambiri.

Amphamvu ndi odalirika

Nthawi 100 zodalirika kuposa chubu la elekitironi, kukana kugwedezeka, kukana kugwedezeka, zomwe sizingafanane ndi chubu la elekitironi.Kuonjezera apo, kukula kwa transistor ndi gawo limodzi mwa magawo khumi mpaka zana limodzi la kukula kwa chubu la electron, kutentha kochepa kwambiri, kungagwiritsidwe ntchito popanga maulendo ang'onoang'ono, ovuta, odalirika.Ngakhale kupanga kwa transistor ndikolondola, njirayi ndi yosavuta, yomwe imathandizira kukonza kachulukidwe kazinthu.
