Intshayelelo kwiimpawu zedayidi

Isalathiso

intshayelelo emfutshane

Idiode sisixhobo esinee-electrode ezimbini, isihlanganisi se-PN esenziwe ngohlobo lwe-P-semiconductor kunye nohlobo lwe-N semiconductor. Okwangoku inokuhamba kuphela ukusuka kwi-anode yedayode kwaye iphume kwi-cathode. Inendawo yombane eyakhelweyo kwaye isetyenziswa ngokubanzi kwiisekethi zokulungisa.

Iimpawu ezintle

Kwisekethe, i-cathode ye-diode iqhagamshelwe kwisiphelo se-voltage esezantsi, kwaye i-anode idityaniswe kwisiphelo se-high-voltage. Ngeli xesha, idiode iya kuvulwa.Leli lizwe libizwa ngokuba kukukhetha phambili. Xa umahluko wevolthi phakathi kweziphelo zombini zedayode incinci kakhulu, idayode ayinakuvulwa. Ngenxa yokuba i-diode yangoku incinci kakhulu. Kuphela kuxa umbane we-diode oya phambili ufikelela kwixabiso elithile (elona futhe lisezantsi elisezantsi lesilicon diode ngu-0.6V, elona ziko lisezantsi le-germanium diode yi-0.2V) apho i-diode iya kuvulwa ngokupheleleyo. Emva kokuvula, i-voltage kwi-diode ihlala ingatshintshi (malunga ne-0.7V yee-diode ze-silicon kunye ne-0.3V ye-germanium diode) Le meko ibizwa ngokuba yi-diode phambili ye-voltage drop.

Ukuguqula iimpawu

Kwisekethe, xa i-cathode ye-diode iqhagamshelwe kwisiphelo sevolthi ephezulu kwaye i-anode iqhagamshelwe kwisiphelo sevolthi esezantsi, i-diode ikwisimo sokunqunyulwa ngeli xesha, kwaye akukho kuhamba ngoku. Xa i-diode ikwi-bias ephambeneyo, ukuba kusekho ubuthathaka obukhoyo ngoku ohamba nge-diode, le yimeko yokuvuza. Xa i-voltage ebuyela umva kwi-diode eqhelekileyo ifikelela kwixabiso elithile, i-reverse yangoku iya kunyuka kabukhali.Ngoku ngeli xesha, i-diode iya kuphulukana nokuqhuba kwayo okungahambisiyo kwaye kuya konakaliswa kukonakala okubuyela umva.
