Nyob hauv Schottky diode, a semiconductor-hlau hlws ris yog tsim los ntawm ib tug semiconductor thiab ib tug hlau, yog li tsim ib tug Schottky barrier. N-hom semiconductor ua raws li cathode thiab sab hlau ua raws li anode ntawm diode. Qhov teeb meem Schottky no ua rau ob qho tib si qis rau pem hauv ntej voltage poob thiab hloov ceev heev.
Lub hom phiaj ntawm Schottky diode yog dab tsi?
Schottky diodes yog siv rau lawvqis tig-rau qhov hluav taws xob, lub sijhawm rov qab sai thiab tsis tshua muaj zog ntawm cov zaus ntau dua. Cov yam ntxwv no ua rau Schottky diodes muaj peev xwm kho qhov tam sim no los ntawm kev ua kom muaj kev hloov pauv sai ntawm kev coj mus rau lub xeev thaiv.
Schottky diode ua haujlwm li cas hauv kev tsis ncaj ncees?
Forward Biased Schottky Diode
Ntawm lub diode, thaum rau pem hauv ntej bias voltage yog siv, ntau electrons yog tsim nyob rau hauv cov hlau thiab conductor. Thaum siv qhov hluav taws xob ntau dua 0.2 volts, cov hluav taws xob dawb tsis tuaj yeem txav mus los ntawm kev sib tshuam. Vim qhov tam sim no yuav ntws los ntawm diode.
Koj siv Schottky diode hauv Circuit Court li cas?
Lub voj voog nyob rau sab laug muaj cov pa diode, ib qho ntawm sab xis yog Schottky diode. Ob leeg yog powered nrog 2V DC qhov chaw. Cov pa diode siv 0.7V, tawm tsuas yog 1.3V los ua lub zog thauj khoom. Nrog rau nws qhov qis dua rau pem hauv ntej voltage poob, Schottky diode siv tsuas yog 0.3V, tawm hauv 1.7V kom lub zog thauj khoom.
Thaum lub Schottky diode yog kev tsis ncaj ncees rau pem hauv ntej?
Thaum rau pem hauv ntej tsis ncaj ncees lawm, kev coj mus los ntawm kev sib tshuam tsis pib kom txog rau thaum qhov hluav taws xob sab nraud mus txog qhov "lub hauv caug voltage" ntawm qhov taw tes tam sim no nce nrawm thiab rau silicon diodes qhov voltage xav tau rau kev xa mus tom ntej yuav tshwm sim yog nyob ib ncig ntawm0.65 txog 0.7 volts raws li qhia.
