Yuav ua li cas los txiav txim siab lub zog siab MOSFET yog kub hnyiab los ntawm burnout

(1) MOSFET yog cov khoom siv hluav taws xob tswj hluav taws xob, thaum transistor yog cov khoom siv tam sim no. Hauv kev tsav tsheb tsis muaj peev xwm, tsav tam sim no me me, yuav tsum xaivMOSFET; thiab nyob rau hauv lub teeb liab voltage yog tsawg, thiab tau cog lus tias yuav siv ntau tam sim no los ntawm hluav taws xob nuv ntses tshuab tsav theem tej yam kev mob, yuav tsum tau xaiv transistor.

 

(2) MOSFET yog kev siv cov khoom siv hluav taws xob feem ntau, yog li hu ua unipolar ntaus ntawv, thaum lub transistor yog tias muaj feem ntau ntawm cov neeg nqa khoom, tab sis kuj yog kev siv me me ntawm cov cab kuj conductive. Nws yog hu ua bipolar ntaus ntawv.

 

(3) Ib coMOSFET qhov chaw thiab cov dej ntws tuaj yeem hloov pauv rau kev siv lub rooj vag voltage tuaj yeem yog qhov zoo lossis qhov tsis zoo, qhov yooj yim dua li qhov transistor yog qhov zoo.

 

(4) MOSFET tuaj yeem ua haujlwm hauv qhov tam sim no me me thiab tsis tshua muaj hluav taws xob tsawg, thiab nws cov txheej txheem tsim khoom tuaj yeem yooj yim heev rau kev sib koom ua ke ntau MOSFETs hauv silicon nti, yog li MOSFETs nyob rau hauv loj-scale integrated circuits tau dav siv.

 

(5) MOSFET muaj qhov zoo ntawm cov tswv yim impedance siab thiab tsis tshua muaj suab nrov, yog li nws kuj tau siv dav hauv ntau yam khoom siv cuab yeej hluav taws xob. Tshwj xeeb tshaj yog nrog lub teb nyhuv tube ua tag nrho cov khoom siv hluav taws xob input, tso zis theem, tuaj yeem tau txais cov transistor dav dav yog qhov nyuaj rau kev ua haujlwm.

 

(6)MOSFETs tau muab faib ua ob pawg: liab hlws ris hom thiab insulated rooj vag hom, thiab lawv manipulation cov ntsiab lus yog tib yam.

 

Qhov tseeb, lub triode yog pheej yig dua thiab siv tau yooj yim dua, feem ntau siv rau hauv cov laus cov neeg nuv ntses tsawg zaus, MOSFET rau high-frequency high-speed circuits, high-tam sim no zaus, yog li hom tshiab ntawm high-frequency ultrasonic fishers, qhov tseem ceeb. yog covloj MOS. Feem ntau hais lus, cov nqi qis, kev siv dav dav ntawm thawj zaug xav txog kev siv cov transistors, tsis yog tias koj xav xav txog MOS.

 

MOSFET yog cov laj thawj tawg thiab cov kev daws teeb meem raws li hauv qab no

 

Ua ntej, cov tswv yim tiv thaiv ntawm MOSFET nws tus kheej yog siab heev, thiab lub rooj vag - qhov chaw inter-electrode capacitance yog me me, yog li nws yog qhov cuam tshuam rau sab nraud electromagnetic teb los yog electrostatic inductance thiab them, thiab tus nqi me me tuaj yeem tsim. nyob rau hauv inter-electrode capacitance ntawm qhov tsim nyog high voltage (U = Q / C), yuav puas lub raj. Txawm hais tias MOS cov tswv yim ntawm lub tshuab nuv ntses hluav taws xob muaj kev tiv thaiv kev tiv thaiv zoo li qub, tab sis tseem yuav tsum tau kho nrog kev saib xyuas, hauv kev khaws cia thiab xa khoom ntawm cov khoom siv hlau zoo tshaj plaws lossis cov khoom siv ntim khoom, tsis txhob muab tso rau hauv qhov yooj yim los tua static high voltage. chemical cov ntaub ntawv los yog chemical fibers. Sib dhos, commissioning, yam, tsos, workstation, thiab lwm yam yuav tsum tau zoo heev grounding. Txhawm rau kom tsis txhob muaj kev cuam tshuam ntawm tus neeg teb xov tooj electrostatic cuam tshuam, xws li yuav tsum tsis txhob hnav nylon, tshuaj fiber ntau cov khaub ncaws, tes los yog ib yam dab tsi ua ntej kov cov thaiv kev sib txuas yog qhov zoo tshaj plaws rau kev sib txuas hauv av. Rau cov cuab yeej coj ncaj thiab dabtsi yog khoov los yog phau ntawv vuam, kev siv cov cuab yeej yog tsim nyog rau qhov zoo tshaj hauv av.
