Stability ntawm diodes nyob rau hauv ib puag ncig kub

Qhov cuam tshuam ntawm qhov kub thiab txias ib puag ncig ntawm diodes
Thermal excitation ntawm tus nqi nqa khoom
Lub hauv paus ntsiab lus ua haujlwm ntawm diodes yog nyob ntawm kev txav ntawm cov khoom thauj khoom hauv cov khoom siv semiconductor. Nyob rau hauv ib puag ncig kub, thermal excitation phenomenon nyob rau hauv semiconductors ua ntau pronounced, ua rau ib tug tseem ceeb nce nyob rau hauv tus naj npawb ntawm cov neeg nqa khoom pub dawb. Qhov tshwm sim no cuam tshuam ncaj qha rau cov yam ntxwv ntawm lub diode, ua rau muaj kev nce hauv nws cov dej ntws tam sim no, uas cuam tshuam rau kev ruaj ntseg thiab kev ntseeg siab ntawm cov cuab yeej.

Nce nyob rau hauv cov dej ntws tam sim no
Nyob rau hauv qhov chaw kub kub, qhov dej ntws tam sim no (piv txwv li rov qab tam sim no) ntawm diodes ho nce. Qhov no yog vim hais tias thaum kub nce, lub zog bandgap ntawm cov khoom siv semiconductor txo qis, ua kom yooj yim dua los tsim cov hluav taws xob dawb thiab lub qhov khub, uas ua rau muaj qhov nce rov qab tam sim no. Qhov tshwm sim no tsis tsuas yog cuam tshuam rau kev ua haujlwm ntawm lub diode, tab sis kuj tseem tuaj yeem ua rau tsis ua haujlwm hauv Circuit Court.

Shortening lifespan
Kev kub kub ib puag ncig yuav ua rau cov txheej txheem kev laus ntawm cov khoom siv diode. Vim yog qhov sib txuam ntawm cov cua sov, cov khoom ntim ntawm lub diode tuaj yeem degrade, yog li cuam tshuam rau lub zog thiab kev sib khi ntawm cov cuab yeej. Kev pabcuam lub neej ntawm diodes raug kub siab rau lub sijhawm ntev yog feem ntau luv luv, uas cuam tshuam rau kev ntseeg tau ntawm tag nrho cov tshuab hluav taws xob.

Kev sib tw ntawm diodes nyob rau hauv ib puag ncig kub
Risk ntawm thermal runaway
Nyob rau hauv qhov kub thiab txias, qhov nce ntawm cov dej ntws tam sim no ntawm diodes tuaj yeem ua rau thermal runaway. Qhov no yog lub voj voog vicious: qhov nce ntawm qhov kub thiab txias ua rau muaj qhov nce hauv cov dej ntws tawm, uas ua rau qhov kub thiab txias ntxiv. Yog tias tsis siv qhov ntsuas kub kom zoo, lub diode yuav ua tsis tiav vim overheating.

hluav taws xob tawg
Kev kub siab kuj tuaj yeem ua rau txo qis ntawm qhov tawg ntawm diodes. Nyob rau hauv ib txwm muaj xwm txheej, kev tawg hluav taws xob yog qhov ntsuas ntawm qhov siab tshaj plaws uas lub diode tuaj yeem tiv taus nyob rau hauv cov xwm txheej rov qab. Txawm li cas los xij, ntawm qhov kub thiab txias, kev hloov pauv ntawm cov khoom hluav taws xob ntawm cov khoom siv tuaj yeem ua rau txo qis ntawm qhov tawg, yog li ua rau muaj kev pheej hmoo ntawm diode tawg hauv kev siv tswv yim.

Thermal qaug zog thiab thermal stress
Nrog kev hloov pauv ntawm qhov kub thiab txias, cov khoom siv sab hauv ntawm lub diode tuaj yeem ntsib kev qaug zog thiab thermal stress. Cov xwm txheej no tuaj yeem ua rau microcracks thiab qhov tsis xws luag hauv cov qauv sab hauv ntawm transistors, yog li cuam tshuam rau lawv lub sijhawm ntev thiab kev ntseeg siab.

Cov tswv yim rau kev txhim kho diode stability nyob rau hauv high-temperature ib puag ncig
Xaiv cov ntaub ntawv kub resistant
Nws yog ib qho tseem ceeb uas yuav tau xaiv cov ntaub ntawv tsim nyog semiconductor txhawm rau txhim kho kev ruaj ntseg ntawm diodes hauv qhov chaw kub kub. Piv txwv li, cov ntaub ntawv dav dav xws li silicon carbide (SiC) thiab gallium nitride (GaN) tau siv dav hauv cov khoom siv hluav taws xob kub kub vim lawv qhov ua tau zoo ntawm qhov kub thiab txias. Cov ntaub ntawv no muaj cov thermal conductivity siab thiab tsis tshua muaj hluav taws xob tsim cov yam ntxwv, thiab tuaj yeem tswj xyuas hluav taws xob ruaj khov ntawm qhov kub thiab txias.

Optimize ntaus ntawv tsim
Hauv kev tsim cov txheej txheem ntawm diodes, kev ntsuas xws li optimizing electrode qauv, txo cov kab mob parasitic thiab capacitance tuaj yeem txo qhov cuam tshuam ntawm qhov kub thiab txias ntawm lawv qhov kev ua tau zoo. Tsis tas li ntawd, siv cov txheej txheem ntim khoom tsim nyog, xws li ntim cov khoom siv ceramic, tuaj yeem txhim kho lub zog thiab kev sib khi ntawm diodes nyob rau hauv qhov chaw kub.

Kev tswj cua sov
Kev tswj xyuas kom sov zoo yog qhov tseem ceeb rau kev tswj xyuas qhov ruaj khov ntawm diodes hauv qhov chaw kub kub. Cov kws ua haujlwm tuaj yeem txo qhov kev ua haujlwm kub ntawm diodes thiab zam cov cuab yeej tsis ua haujlwm los ntawm kev ua kom sov dhau los ntawm kev ntxiv cov dab dej kub, ua kom zoo dua qhov kev teeb tsa hauv Circuit Court, thiab siv cov khoom siv hluav taws xob zoo.

Kev ntsuam xyuas thiab kev ntsuam xyuas tsis tu ncua
Kev ntsuam xyuas kev ntseeg siab thiab kev ntsuas tsis tu ncua yog tsim nyog los xyuas kom meej lub sijhawm ntev ntawm diodes nyob rau hauv qhov chaw kub kub. Los ntawm txoj kev ntsuas kev ua neej kom nrawm, ntsuas qhov kub thiab txias, thiab lwm txoj hauv kev, qhov muaj peev xwm kub siab tsis ua haujlwm ntawm diodes tuaj yeem txheeb xyuas ua ntej thiab kev txhim kho tuaj yeem ua tau raws sijhawm.
