Xaiv Scottky diodes nrog txo qis rau pem hauv ntej voltage yuav ua tau zoo txhim kho lub roj teeb.
(2) Rov qab cov kev thim hluav taws xob tiv thaiv (VRRM)
Thim rov qab tiv thaiv voltage yog hais txog qhov ntau tshaj plaws uas yog schottky diode yuav tiv taus thaum thim biased. Nyob rau hauv kev sib txuas lus kev sib txuas lus, ntau yam kev hloov pauv hloov pauv, xws li cov thim rov qab nrog cov voltage ntawm cov diode tsis txaus, nws yuav tawg cia thiab puas, ua rau cov kab ke tsis ua haujlwm. Yog li ntawd, nws yog qhov tseem ceeb los xaiv schottky donges nrog txaus thim rov qab raws li kev sib txuas lus Circuit Court thiab ntau tshaj plaws tau rov qab voltage. Piv txwv li, nyob rau hauv lub siab -}}}}}}}}}}}}} }iod with nrog kev ua haujlwm siab xav tau kev ua haujlwm hauv kev ua haujlwm hluav taws xob ib puag ncig.
(3) to tam sim no (ir)
Kev xau dej tam sim no yog qhov tam sim no uas ntws los ntawm kev ua si schottky thaum nws thim rov qab. Raws li qhov kub nce ntxiv, lub xau dej tam sim no yuav ua rau nce ntxiv. Hauv kev sib txuas lus kev sib txuas lus, ntau dhau dej ntws tam sim no tuaj yeem nce kev siv hluav taws xob thiab txo lub zog txuag ntawm Circuit Court. Tshwj xeeb tshaj yog nyob rau hauv qis - fais fab sib txuas lus xws li IOT sensor nodes, qhov kev cuam tshuam ntawm lub roj teeb lub neej muaj ntau tshaj. Yog li ntawd, thaum xaiv, saib xyuas yuav tsum tau them rau cov toast tam sim no ntawm Diode, tshwj xeeb tshaj yog cov to taub tam sim no muaj nyob rau hauv high- qhov chaw ib puag ncig.
(4) lub sijhawm rov qab rov qab (TRR)
Lub sijhawm rov qab rov qab ntawm Schottky Diodes yog luv heev, feem ntau nyob rau hauv nanosecond ntau. Qhov no muab nws kom zoo dua ntawm high- zaus hloov pauv hloov tsheb, txo kev hloov chaw thiab kev txhim kho hluav taws xob ua tau zoo. Nyob rau hauv kev sib txuas lus sib txuas lus, xws li high- Ceev Digital ua kev ua voj voog, thiab lwm yam. Xaiv Scottky diodes nrog luv rov qab lub sij hawm rov qab yuav ua kom cov ruaj khov thiab kev ntseeg tau ntawm lub sijhawm siab thaum siab- kev ua haujlwm.
2. Xaiv cov lus qhia rau schottky disies nyob rau hauv ntau qhov kev thov sau cov xwm txheej ntawm kev sib txuas lus circuits
(1) Kev kub ceev Digital teeb liab kev ua haujlwm
Nyob rau hauv high - Ceev digital teeb liab kev ua haujlwm, xws li high} Cov kev xa khoom ceev thiab kev sib kis tau nrawm nrawm heev. Qhov no yuav tsum muaj kev npau taws nyob rau hauv lub hauv paus hniav kom tau nrawm nrawm nrawm nrawm thiab qis dua voltage poob mus rau kev teeb liab ncua thiab poob. Piv txwv li, hauv high - ceev analog} Txij ntawm no, schottky diodes nrog txo cov qauv hluav taws xob hauv ntej thiab cov qauv luv luv, yuav tsum tau xaiv kom tau raws li qhov yuav tsum tau ua.
