A Schottky diode yog ib hom hluav taws xob tiv thaiv, uas tseem hu ua barrier diode. Nws yog dav siv nyob rau hauv sib txawv daim ntawv thov xws li ib tug tov khoom, nyob rau hauv lub xov tooj cua zaus daim ntawv thov, thiab raws li ib tug rectifier nyob rau hauv lub hwj chim daim ntawv thov. Nws yog qhov tsawg voltage diode. Lub zog poob qis dua piv rau PN junction diodes.
Schottky diode siv rau 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.
Diode siv qhov twg?
Txawm hais tias tsis muaj dab tsi ntau dua li cov khoom siv yooj yim ob-pin semiconductor, diodes tseem ceeb heev rau cov khoom siv hluav taws xob niaj hnub no. Qee qhov ntawm lawv cov ntawv thov feem ntau suav nrog tig AC rau DC, cais cov cim los ntawm cov khoom siv, thiab sib xyaw cov cim. Lub diode muaj ob 'sab' thiab txhua sab yog doped sib txawv.
Schottky diode yog dab tsi thiab nws ua haujlwm li cas?
Nyob hauv Schottky diode, semiconductor-hlau hlws ris yog tsim los ntawm ib qho semiconductor thiab hlau, yog li tsim 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.
Kuv tuaj yeem nrhiav Schottky diode nyob qhov twg?
Rov qab qhov kev xeem cojntawm lub multimeter los ntawm qhov muab qhov kev ntsuam xyuas zoo coj mus rau cathode thiab qhov kev sim ntau ua rau lub anode ntawm diode. Saib seb lub multimeter emits ib lub suab. Yog hais tias lub multimeter tsis suab nrov, Schottky diode ua haujlwm raug.
