Gabatarwa ga halayen diodes

Magana

taƙaitaccen gabatarwa

Diode na’ura ce mai dauke da wayoyi guda biyu, mahada PN wanda ya kunshi na semiconductor na P da na semiconductor na N. A halin yanzu ana iya shigowa ne daga anode diode kuma ana fita daga cathode.Yana da wutar lantarki da kanta ta kera ta kuma ana amfani da ita gaba daya a cikin da'irar masu gyara.

Halaye masu kyau

A cikin da'ira, cathode na diode an haɗa shi zuwa ƙarshen ƙaramin ƙarfin lantarki, kuma anode an haɗa shi zuwa ƙarshen mai ƙarfin lantarki. A wannan lokacin, za a kunna diode ɗin. Wannan jihar ana kiranta gaba son rai. Lokacin da bambancin wutar lantarki tsakanin iyakar biyu na diode yayi kadan, ba za a iya kunna diode ba. Saboda halin yanzu ta hanyar diode kadan ne. Sai kawai lokacin da ƙarfin gaban diode ya kai wani ƙima (mafi ƙarancin juya-on ƙarfin silinon diode shine 0.6V, ƙarfin wuta mafi ƙasƙanci na germanium diode shine 0.2V) za a kunna diode ɗin gaba ɗaya. Bayan kunnawa, wutar lantarki a cikin diode din bata canza ba (kimanin 0.7V na dikedon silicon da kuma kusan 0.3V na dioxes na germanium) .Ana kiran wannan yanayin diode forward voltage digo.

Halaye na baya

A cikin da'irar, lokacin da cathode na diode ya haɗu da ƙarshen babban ƙarfin lantarki kuma anode an haɗa shi da ƙarshen ƙarfin lantarki, diode ɗin yana cikin yanayin yankewa a wannan lokacin, kuma babu wani kwararar da ke gudana a yanzu.Wannan jihar ana kiranta bias bias. Lokacin da diode din yake cikin son zuciya, idan har yanzu akwai ragwancin rashi da ke gudana ta cikin diode, wannan shine yanayin kwararar ruwa. Lokacin da wutar lantarki ta baya a cikin diode ta yau da kullun ta kai wani darajar, ta baya za ta karu sosai .. A wannan lokacin, diode din zai rasa ikon sarrafa shi ta hanyar rashin hanya kuma zai lalace ta hanyar rugujewar baya.
