Schottky diode: kev daws teeb meem rau qhov poob qis

Cov yam ntxwv yooj yim
Tsawg pem hauv ntej siab poob
Qhov tseem ceeb tshaj plaws yog nws qhov tsis tshua muaj hluav taws xob poob qis (feem ntau ntawm {{0}}.2V thiab 0.4V), uas yog qis dua li 0.7V ntawm cov silicon diodes zoo tib yam. Cov yam ntxwv no ua rau Schottky diodes ua tau zoo nyob rau hauv qis-voltage circuits, zoo txo ​​hwj chim noj thiab txhim kho system efficiency.

Kev kub ceev hloov
Los ntawm kev siv cov hlau semiconductor hlws ris es tsis txhob ntawm cov tsoos PN hlws ris, cov cab kuj txhaj tshuaj thiab dissipation ceev ceev, uas ua rau muaj kev hloov ceev heev. Qhov no ua rau nws haum rau high-speed hloov circuits thiab high-frequency daim ntaub ntawv.

Tsawg rov qab lub sij hawm rov qab
Lub sij hawm rov qab rov qab yog luv heev, feem ntau nyob rau theem nanosecond. Cov yam ntxwv no ua rau nws ua tau zoo hauv kev hloov cov khoom siv hluav taws xob thiab RF daim ntawv thov, txo qhov kev poob qis.

Kev kub siab ua haujlwm
Ua kom qis qis rau pem hauv ntej siab poob thiab kev kub ceev hloov cov yam ntxwv nyob rau hauv qhov kub thiab txias ib puag ncig, haum rau kev ua haujlwm hnyav.

txoj cai ua haujlwm
Nws yog tsim los ntawm kev sib cuag ntawm hlau thiab semiconductor, nrog rau sab hlau muab electrons thiab semiconductor sab feem ntau yog N-hom khoom. Thaum no hlau semiconductor hlws ris yog rau pem hauv ntej biased, electrons migrate los ntawm cov hlau mus rau lub semiconductor, tsim ib tug tam sim no; Thaum rov qab biased, yuav luag tsis muaj tam sim no dhau los ntawm electrons nyuaj rau migrate los ntawm semiconductor mus rau hlau. Cov yam ntxwv no txiav txim siab qhov qis qis rau pem hauv ntej thiab lub sijhawm teb ceev ntawm Schottky diodes.

daim ntawv thov cheeb tsam
Hloov hom Fais fab mov
Hauv cov khoom siv hluav taws xob hloov hluav taws xob, nws tau siv dav rau kev kho kom haum xeeb thiab kev ua haujlwm pub dawb. Nws qhov qis rau pem hauv ntej voltage poob thiab ceev hloov cov yam ntxwv tuaj yeem txhim kho qhov ua tau zoo ntawm cov khoom siv hluav taws xob thiab txo qhov kub poob. Piv txwv li, nyob rau hauv DC-DC converters, Schottky diodes yuav siv tau raws li cov zis rectifying pab kiag li lawm los txo qhov voltage poob ntawm cov zis voltage thiab txhim kho conversion efficiency.

RF Circuit Court
Nws kuj tseem muaj cov ntawv thov tseem ceeb hauv RF circuits. Vim nws tsis tshua muaj peev xwm thiab cov yam ntxwv ntawm cov lus teb ceev, nws feem ntau yog siv hauv RF mixers thiab detectors los txhim kho cov teeb liab ua kom ceev thiab raug.

roj teeb charger
Hauv cov roj teeb chargers, nws yog siv los tiv thaiv qhov rov qab tam sim no. Tom qab lub charger raug kaw lawm, tam sim no ntawm lub roj teeb yuav ntws rov qab rau hauv lub charger. Lub sijhawm no, qhov qis qis rau pem hauv ntej poob thiab cov yam ntxwv kho kom zoo tuaj yeem tiv thaiv qhov xwm txheej no kom tsis txhob tshwm sim thiab tiv thaiv lub roj teeb thiab lub charger.

Photovoltaic system
Hauv cov tshuab photovoltaic, nws yog siv los tiv thaiv qhov rov qab tam sim no hauv cov hnub ci vaj huam sib luag thaum hmo ntuj lossis lub teeb qis. Vim qhov tsis tshua muaj hluav taws xob poob tus yam ntxwv ntawm Schottky diodes, lawv tuaj yeem ua kom lub zog ua haujlwm tau zoo thiab txo qis zog.

Automotive Electronics
Hauv automotive electronics, nws yog siv rau kev tiv thaiv hluav taws xob thiab kev tswj hluav taws xob. Nws cov kev ua haujlwm siab thiab kev ntseeg siab tau ua rau nws siv dav hauv tsheb pib tshuab, teeb pom kev zoo, thiab ntau yam sensor circuits.

Cov ntaub ntawv thov tshwj xeeb
Siv tau zoo Switching Power Supply
Ib lub tuam txhab tau tsim muaj kev hloov pauv hluav taws xob zoo uas siv Schottky diodes ua cov khoom siv hluav taws xob. Thaum lub sij hawm sim, engineers pom tias piv rau cov tsoos silicon diodes, Schottky diodes ho txo ​​qhov tso zis voltage poob ntawm lub hwj chim mov thiab txhim kho tag nrho cov efficiency. Los ntawm kev siv Schottky diodes, qhov ua tau zoo ntawm cov khoom siv hluav taws xob hloov pauv tau zoo dua los ntawm ntau dua 5%, thaum txo cov cua sov tsim thiab txhim kho kev ntseeg tau.

Optimization ntawm photovoltaic system
Lub photovoltaic system integrator tau txais Schottky diodes nyob rau hauv nws cov tiam tshiab hnub ci vaj huam sib luag system los tiv thaiv rov qab tam sim no. Kev sim cov ntaub ntawv qhia tau hais tias lub zog poob ntawm lub cev tau raug txo los ntawm 10%. Nyob rau hauv hmo ntuj los yog tsis tshua muaj teeb pom kev zoo, lub zog hluav taws xob ntawm lub hnub ci vaj huam sib luag yog zoo khaws cia, kev txhim kho efficiency thiab kev lag luam ntawm tag nrho cov photovoltaic system.

Battery Management System
Hauv kev tswj hwm roj teeb (BMS) rau lub tsheb hluav taws xob, cov neeg tsim khoom siv Schottky diodes los tiv thaiv kev thim rov qab ntawm lub roj teeb. Cov txiaj ntsig kev sim qhia tau hais tias tus yam ntxwv tsis tshua muaj hluav taws xob poob zoo txo ​​qis lub zog poob ntawm lub roj teeb, thaum nws cov yam ntxwv hloov pauv siab ua kom cov tshuaj tiv thaiv ceev ntawm BMS, ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub roj teeb.
