Olukey piav qhia qhov tsis sib xws ntawm MOSFET rau koj!

Raws li ib qho ntawm cov khoom siv yooj yim tshaj plaws hauv thaj chaw semiconductor, MOSFET tau siv dav hauv ob qho tib si IC tsim thiab board-theem Circuit Court daim ntawv thov. Yog li koj paub ntau npaum li cas txog qhov ntau yam ntawm MOSFET? Raws li tus kws tshaj lij hauv nruab nrab thiab qis voltage MOSFETs,Olukeyyuav piav qhia rau koj paub meej txog ntau yam ntawm MOSFETs!

VDSS qhov siab tshaj plaws ntws-qhov chaw tiv taus hluav taws xob

Qhov hluav taws xob ntws-qhov hluav taws xob thaum lub ntws ntws tam sim no nce mus txog tus nqi tshwj xeeb (surges sharply) nyob rau hauv ib qho kub thiab qhov rooj-qhov luv luv Circuit Court. Qhov dej-qhov hluav taws xob hauv qhov no tseem hu ua avalanche breakdown voltage. VDSS muaj qhov zoo kub coefficient. Ntawm -50 ° C, VDSS yog kwv yees li 90% ntawm qhov ntawd ntawm 25 ° C. Vim qhov nyiaj pub dawb feem ntau tshuav nyob rau hauv ib txwm tsim, avalanche tawg voltage ntawmMOSFETyog ib txwm ntau dua qhov nominal rated voltage.

Olukey cov lus ceeb toom sov: Txhawm rau kom ntseeg tau cov khoom lag luam, raws li kev ua haujlwm tsis zoo, nws raug pom zoo tias qhov ua haujlwm voltage yuav tsum tsis pub tshaj 80 ~ 90% ntawm tus nqi ntsuas.

VGSS qhov siab tshaj plaws qhov rooj tiv thaiv hluav taws xob

Nws hais txog tus nqi VGS thaum qhov rov qab tam sim no ntawm lub rooj vag thiab qhov chaw pib nce sharply. Tshaj qhov nqi hluav taws xob no yuav ua rau dielectric tawg ntawm lub rooj vag oxide txheej, uas yog kev puas tsuaj thiab irreversible tawg.

ID siab tshaj qhov ntws tawm tam sim no

Nws hais txog qhov siab tshaj plaws tam sim no tso cai rau hla ntawm qhov ntws thiab qhov chaw thaum lub teb cuam tshuam transistor ua haujlwm ib txwm. Kev khiav hauj lwm tam sim no ntawm MOSFET yuav tsum tsis pub tshaj ID. Qhov no parameter yuav derate li junction kub nce.

IDM siab tshaj pulse ntws-qhov tam sim no

Reflects theem ntawm mem tes tam sim no uas lub cuab yeej siv tau. Qhov parameter no yuav txo qis thaum qhov sib txuas kub nce. Yog tias qhov ntsuas no tsawg dhau, lub kaw lus yuav muaj kev pheej hmoo ntawm kev tawg los ntawm tam sim no thaum kuaj OCP.

PD siab tshaj lub zog dissipation

Nws hais txog qhov siab tshaj plaws ntws-qhov hluav taws xob dissipation tso cai yam tsis muaj kev cuam tshuam qhov kev ua tau zoo ntawm thaj chaw cuam tshuam transistor. Thaum siv, qhov tseeb siv hluav taws xob ntawm lub teb cov nyhuv transistor yuav tsum tsawg dua li ntawm PDSM thiab tawm ntawm cov npoo. Qhov no parameter feem ntau derates li junction kub nce.

TJ, TSTG kev khiav hauj lwm kub thiab cia ib puag ncig kub ntau yam

Ob qhov kev ntsuas no ntsuas qhov ntsuas kub ntawm qhov sib txuas tau tso cai los ntawm cov cuab yeej ua haujlwm thiab chaw cia khoom. Qhov ntsuas kub no yog teem kom ua tau raws li qhov yuav tsum tau ua ntawm lub neej ua haujlwm yam tsawg kawg nkaus. Yog tias lub cuab yeej tau ua haujlwm nyob rau hauv qhov ntsuas kub no, nws lub neej ua haujlwm yuav ntev heev.
