Kev xaiv Diode txiav txim siab li cas lub neej ntawm cov cuab yeej kho mob?

 

Nws yog kev ntxias kom xav tias kev ntseeg siab yog ib yam uas koj tuaj yeem sim hauv lossis kho tom qab. Qhov tseeb, feem ntau ntawm nws yog ci rau lub sijhawm koj xaiv ib feem. Ib lub diode xaiv nrog cov npoo nyias nyias yuav ua kom kub thiab ntxhov siab ntau dua rau nws lub neej tag nrho - thiab tsis muaj ntau npaum li cas ntawm cov firmware ntse yuav rov ua qhov ntawd.

Qhov no yog vim li cas xaiv diodes rau cov khoom siv kho mob tsim nyog tiag tiag engineering saib pem hauv ntej:

Tsim - hauv kev xaiv yog nyob ruaj khov. Thaum ib feem tau teev tseg thiab lub rooj tsavxwm tau nteg tawm, nws qhov kev ntxhov siab yog kho rau lub neej ntawm cov khoom.

Kho nws tom qab yog kim. Kev rov tsim dua tshiab, kev tsim nyog, lossis kev rov ua dua tshiab raug nqi ntau dua li kev xaiv qhov zoo thawj zaug.

Me me margins compound. Lub diode khiav ze rau nws cov kev txwv tsis yog tsuas yog pheej hmoo ua tsis tiav - nws muaj hnub nyoog sai dua txhua hnub.

Nyob rau hauv luv luv, lifespan koj xav tau nyob rau hauv lub xyoo kaum yog txiav txim los ntawm lub diode xaiv cov txheej txheem koj thov nyob rau hauv lub xyoo zero.

 

Yog li dab tsi tiag tiag txiav txim siab ntev npaum li cas lub diode - thiab cov cuab yeej nyob ib puag ncig nws - yuav kav ntev npaum li cas? Feem ntau ntawm cov xwm txheej ua haujlwm feem ntau:

Voltage npoo. Ib feem ntsuas tau zoo tshaj qhov ua haujlwm voltage tsis ntxhov siab los ntawm ib txwm spikes, yog li nws muaj hnub nyoog maj mam.

Tam sim no thiab surge headroom. Kev ntsuas tam sim no yooj yim txhais tau tias muaj cua sov tsawg dua thiab hnav tsawg dua thaum thauj khoom.

Derating. Txhob txwm ua haujlwm ib feem hauv qab nws cov kev txwv yog tib lub zog uas muaj zog tshaj plaws rau kev ua neej ntev (ntau ntxiv ntawm qhov no ntxiv).

Thermal tsim. Ua kom qhov sib txuas ua kom txias qeeb txhua qhov cua sov- tsav cov txheej txheem kev laus.

Tsawg to. Ib qho huv si, qis- qhov dej ntws tawm tsawg dua thiab nyob hauv spec ntev dua.

Kev ua tau zoo thiab kev tshuaj ntsuam xyuas. iav -passivated kev tsim kho thiab raug hlawv- nyob rau hauv cov nroj tsuag tawm qhov tsis muaj zog uas ua tsis tau thaum ntxov.

Nco ib qho ntawm cov no thiab koj tau ntsiag to luv lub cuab yeej lub neej ua ntej nws puas tawm hauv lub Hoobkas. Ntsia lawv thiab koj tau tsim nyob rau hauv ntev - lub neej cov khoom siv kho mob.

 

Yog hais tias muaj ib lub tswv yim tsim nyog internalizing, nws yog qhov no: tshav kub yog tus yeeb ncuab ntawm lifespan, thiab derating yog li cas koj ntaus nws.

Muaj ntau txoj cai lij choj hais txog tus ntiv tes xoo - muab los ntawm Arrhenius qauv - uas rau ntau yam khoom, txhua qhov kwv yees li 10℃nce hauv kev ua haujlwm kub tuaj yeem kwv yees li ob npaug ntawm qhov tsis ua haujlwm, lossis muab sib txawv, kwv yees li ib nrab ntawm lub neej xav tau. Nws yog qhov kwv yees, tsis yog txoj cai lij choj (lub neej tiag tiag muaj ntau hom kev ua tsis tiav), tab sis cov kev taw qhia yog pob zeb- khoom: cov khoom txias txias tau ntev dua. Txo qhov kub ntawm qhov sib txuas ua kom lub neej zoo dua qub, txo qhov ua haujlwm ntxov - lub neej tsis ua haujlwm, thiab ua kom ruaj khov ntev - lub sijhawm ua haujlwm.

Rov qab leakage qhia tib zaj dab neeg - nws kuj roughly ob npaug rau txhua txhua 10℃ntawm kub nce, yog li ib tug kub, ntxhov siab diode ob lub hnub nyoog sai thiab leaks ntau raws li nws mus. Cov tswv yim coj tawm yog yooj yim:

Xaiv cov kev ntsuas dav dav kom qhov chaw khiav txias hauv kev siv ib txwm.

Derate rau lub hom phiaj - tsis txhob khiav qhov twg nyob ze qhov siab tshaj plaws voltage, tam sim no, los yog kub.

Tsim kom txias - txhua qib koj chais tawm ntawm kev sib tshuam yuav koj lub neej ua haujlwm.

Qhov no yog kev tsim vaj tsev nyob ntsiag to tom qab muaj zog cov cuab yeej kho mob kev ntseeg siab thiab MTBF tus lej.

 

Lub neej ntev pib nrog xaiv cov khoom uas muaj cov npoo, khiav txias, thiab ua kom tsis tu ncua. Peb tus neeg ua haujlwm pov thawj haum rau daim nqi.
