Cov kev siv ntawm diodes desies hauv kev tiv thaiv kev tiv thaiv ntawm cov khoom sib txuas lus?

1. Cov xob laim kev hem thawj thiab kev tiv thaiv xob coj los ntawm kev sib txuas lus
(1) kev hem thawj
Xob laim yog qhov tshwm sim ntuj ua tau yooj yim uas ua rau muaj cov cim hluav taws xob (lemps Thaum xob laim sib txuas lus lossis cov vaj tse nyob ze, nws tuaj yeem tsim cov kev sib txuas lus, nrog ntau dua, thiab durations li ntawm ob peb nanoseconds mus rau ob peb microseconds. Ib qho ntxiv, xob laim kuj tseem tuaj yeem ua rau cov qauv sib txuas lus los ntawm cov kab hluav taws xob, tsim lub zog hluav taws xob. Yog tias cov kev hloov pauv hloov pauv thiab overcurrent tsis muaj kev ywj pheej, lawv yuav cuam tshuam ncaj qha rau kev sib txuas lus hauv kev sib txuas lus, ua rau muaj kev puas tsuaj los ntawm kev sib tsoo thiab hlawv.
(2) kev tiv thaiv xob laim
Txhawm rau kom ntseeg tau qhov kev ua haujlwm txhim khu kev qha ntawm kev sib txuas lus hauv kev tswj cov chaw, ntau {{qib qib kev tiv thaiv kev ntsuas yuav tsum tau coj. Ntawm lawv, siv TVs diodes rau kev tiv thaiv hauv zos hauv kev sib txuas lus module yog ib qho tseem ceeb txhais tau tias. TVS DIODES tuaj yeem ua tau sai thaum muaj kev tiv thaiv kev nyab xeeb xws li cov tawv nqaij uas muaj ntau yam thiab hluav taws xob overcurrent rau hauv kev sib txuas lus los ntawm kev sib txuas lus.
2. Ua ua haujlwm cov ntsiab cai thiab cov tsis tseem ceeb ntawm TVs Diode
(1) Lub ntsiab cai ua haujlwm
TVs Diode yog hom tshwj xeeb ntawm cov diode uas, nyob rau hauv ib txwm muaj kev ua haujlwm, yog yuav luag tsis cuam tshuam rau txoj haujlwm ib txwm ntawm Circuit Court. Thaum cov kev hloov pauv hloov pauv tshwm sim hauv Circuit Court, TVs Diode yuav teb sai sai, thiab nws txoj kev tawm tsam sab hauv, thiab nws lub xeev qis, luv luv ntawm kev tiv thaiv qis dua hauv av. Tom qab lub trackient overvoltes ploj, cov tvs diode yuav cia li rov qab mus rau lub xeev siab tiv taus rau Circuit Court.
(2) qhov tseem ceeb
Kev rhuav tshem voltage (vbr): hais txog tus nqi voltage uas TVs Diode pib ua. Thaum xaiv, qhov tsim nyog tawg yuam kev voltage yuav tsum tau xaiv raws li kev ua haujlwm zoo ntawm kev tiv thaiv Circuit Court. Feem ntau, rhuav tshem voltage yuav tsum muaj ntau dua qhov kev ua haujlwm siab tshaj plaws ntawm kev tiv thaiv Callcuit Court, thaum tawm ntawm qee lub npoo.
Clamp Voltage (VC): Thaum TVS DIODE yog muab rau, qhov voltage ntawm ob qho kawg yog clamped ntawm lub clampted voltage tus nqi. Qhov qis dua cov clamping voltage, qhov zoo dua cov kev tiv thaiv ua rau muaj kev tiv thaiv Circuit Court.
Tam sim no nqa muaj peev xwm (IPP): Hais txog qhov siab tshaj plaws siab peakse uas TVs Diode tuaj yeem tiv taus. Qhov loj dua tam sim no nqa lub peev xwm, lub zog loj xob laim lub zog uas tvs diodes tuaj yeem tiv taus.
Teb lub sijhawm (Tr): Hais txog lub sijhawm nws yuav siv rau TVs Diode los pib ua los ntawm kev kuaj xyuas cov kev hloov pauv hloov chaw. Lub sijhawm luv luv teb, qhov zoo dua qhov kev cuam tshuam ntawm kev hloov pauv hloov pauv.
3. Xaiv TVs DIODES rau kev sib txuas lus
(1) Xaiv raws li kev ua haujlwm hluav taws xob ntawm kev sib txuas lus module
Kev sib txuas lus module muaj qhov sib txuas ua haujlwm voltage, thaum xaiv cov khoom sib txuas lus, thaum muaj kev xaiv ntau dua li cov hluavtaws hloov kho thiab tawm ntawm qee qhov kev nyab xeeb npoo. Piv txwv li, rau kev sib txuas lus sib txuas lus nrog kev ua haujlwm voltage ntawm 3.3v, ib tvs diode nrog kev sib cav sib cav sib npaug ntawm 5v tuaj yeem xaiv tau.
(2) Xaiv cov hom interface raws li kev sib txuas lus
Kev sib txuas lus modules feem ntau muaj ntau yam cuam tshuam, xws li cov chaw nres nkoj tseem ceeb, yog li ntawd yuav tsum tau xaiv TV uas tsim nyog rau kev tiv thaiv.
Chaw nres nkoj serial: serial chaw nres nkoj chaw nres nkoj feem ntau yog tsawg {- ceev cov paib thiab yuav tsum muaj cov paib hluav taws xob. Koj tuaj yeem xaiv Unidirectional lossis Bidirectional TVs dodes diodes rau kev tiv thaiv, xws li smig series unidirectional TVs dodes.
Ethernet chaw nres nkoj: Ethernet chaw nres nkoj muaj qhov kev xav tau siab thiab nruj yuav tsum tau ua rau teeb liab kev ncaj ncees thiab capital. Tsawg Capacchance thiab Cov Lus Teb Flrays Farrays Diode yuav tsum tau xaiv rau kev tiv thaiv, xws li SRV05F TVs Array.
USB interface: USB interfaces muaj cov qauv sib txawv xws li USB 2.0 thiab USB 3.0, uas kuj muaj kev tiv thaiv sib txawv rau xob laim. Rau USB 2.0 interfaces, pob me, tsawg peev TVs dodes dodces xws li usbc6 {}} 2Sc6 series tuaj yeem xaiv; Rau kev cuam tshuam USB 3.0 cuam tshuam, nws yog qhov tsim nyog los xaiv TVs dodes diodes nrog kev ua tau zoo dua kom tau raws li lawv qhov kev yuav tsum tau ua kom tau sai.
(3) Xaiv raws li xob laim kev tiv thaiv theem
Cov xwm txheej sib txawv nyias muaj nyias yuav tsum muaj rau xob laim kev tiv thaiv kev tiv thaiv qib. Hauv cov cheeb tsam uas muaj kev coj ua hluav taws xob tsis tu ncua, nws yog qhov tsim nyog los xaiv TVs dodes nrog qib kev tiv thaiv ntau dua thiab qib siab. Piv txwv li, nyob rau sab nraum zoov hauv paus thiab lwm yam xwm txheej, TVs muaj peev xwm tam sim no ntawm ob peb lub kilowatts siab ntawm ob peb lub zog high {
4. Daim ntawv thov cov TVs Diode hauv kev sib txuas lus module
(1) Kev tiv thaiv fais fab
Lub hwj chim ntawm kev sib txuas lus module yog ib qho ntawm txoj kev tseem ceeb rau xob laim los txeeb chaw. Ntawm lub hwj chim tawm tswv yim xaus, ntau -}} Kev tiv thaiv qib ntshav yuav tau txais. Thawj theem yuav siv roj ou roj (GDT) lossis varistors (mov) rau kev tiv thaiv ntxhib, tso tawm ntau lub zog rau hauv av; Qib thib ob siv TVs cov TVs dodes Piv txwv li, ib qho sib txawv tuaj yeem txuas nrog hauv cov lus qhia lub zog kawg, ua raws li los ntawm cov TVs Diode hauv parallel, xws li SMaj series.
(2) Kev Tiv Thaiv Kab Teeb Meem
Rau cov teeb liab kab kev sib txuas lus, cov TV txaus nyiam siv yuav tsum tau xaiv rau kev tiv thaiv raws hom thiab tus nqi ntawm lub teeb liab. Parallel TVs Diodes Uiodes tau txuas rau ntawm ob qho kawg ntawm cov teeb liab kab. Thaum lub sijhawm hloov pauv hloov pauv ntawm cov teeb liab kab, cov TVs Diode nrawm rau hauv av, tiv thaiv kab teeb tsa thiab rov qab} {kawg nti. Piv txwv li, Bidirectional TVs diodes xws li SM8s Series Bidirectional TV yuav siv tau rau kev tiv thaiv Rs-485 daim paib.
(3) Kev Tsim Av Hauv Av
Kev cog qoob loo zoo yog tus yuam sij rau kev tiv thaiv lub zog tsim nyog ntawm TVs diodes. Lub hauv paus ntawm kev sib txuas lus sib txuas yuav tsum ua raws li lub hauv paus ntsiab lus kev sib txuas, hauv av, thiab lwm yam hauv av ua ke los ntawm cov khoom siv tsis zoo thiab ua rau lawv muaj zog. Lub hauv paus tsis kam yuav tsum me li ntau tau, feem ntau tsawg dua 4 ω. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau kev zam dhau lub voj loops thiab txo cov electromagnetic cuam tshuam.
