Nhanganyaya kune hunhu hwemadhiodhi

sumo pfupi

Dhiode mudziyo une ma electrode maviri, junction yePN inoumbwa neP-mhando semiconductor uye N-mhando semiconductor.Izvino inogona kungoyerera ichipinda ichibva kune anode yedhodhi uye kuyerera ichibva mukathodhi.Iine yega-yakavakirwa magetsi munda uye inowanzo shandiswa mumatanho ekugadzirisa.

Hunhu hwakanaka

Mune dunhu, iyo cathode yedhiode yakabatana kune yakaderera-magetsi magumo, uye anode yakabatana kune yakakwira-magetsi magumo.Panguva ino, diode ichavhurwa.Iyi nyika inonzi yekumberi kusarura. Kana iwo mutsauko wemagetsi pakati pemakona maviri e diode iri diki kwazvo, diode harigone kuvhurwa. Nekuti iyezvino kuburikidza ne diode idiki kwazvo. Chete kana iyo yekumberi magetsi eiyo diode yasvika pane imwe kukosha (iyo yakadzikira-kudzora-voltage yemesilicon diode iri 0.6V, iyo yakadzikira-kutenderera-magetsi emagetsi egermanium diode iri 0.2V) ndiyo diode rinozadziswa zvizere. Mushure mekutendeuka, iyo voltage pamhepo diode inoramba isina kuchinjika (inenge 0.7V yesilicon diode uye ingangoita 0.3V yegermanium diode) Iyi mamiriro anonzi diode kumberi voltage kudonha.

Reverse hunhu

Mudunhu, kana cathode yedhayeti yakabatana nemagetsi emagetsi ekupedzisira uye iyo anode yakabatana kune yakaderera magetsi magumo, diode iri munzvimbo yakatemwa panguva ino, uye hapana kuyerera kwazvino.Iyi nyika inonzi reverse bias. Kana diode iri mukutendeuka, kana kuchine isina simba yazvino kuyerera kuburikidza nedhodhi, iyi ndiyo mamiriro ekudonha. Kana iyo voltage yekumusoro ichipfuura neyakajairika diode inosvika pane imwe kukosha, iyo yekumashure yazvino ichawedzera zvakanyanya.Panguva ino, diode icharasikirwa neayo unidirectional kuitisa uye ichakanganiswa nekudzosera kuparara.
