Tsis muaj ib txoj kev ntawm kuaj mosfes (qhov tseeb, lwm yam khoom siv) hauv Circuit Court.

Hauv qhov no, MOSFETs puas qhib lossis kaw?

Cov lus teb luv luv yog kuv xav tau ib MOSFET rau poob as ib qhib Circuit Court vim over-temperatureconditions. Tsab ntawv xov xwm wikipedia no qhia tias: Ua kom indrain-rau-qhov chaw tsis kam. Ntau yam ntawm MOSFET cua sov athigh tam sim no nyob rau hauv cov coj - uas tau yooj yim heev unsoldert lawv tus kheej tsis muaj cov MOSFET ua tsis tiav !

Ib tug kuj yuav nug, dab tsi ua rau MosFet ua tsis tiav? Cov ua rau ntawm no ua tsis tiav yog ib tug heev highvoltage, ceev heev transient spike (uas tej zaum yuav positiveornegative mus). Yog hais tias xws li ib tug spike tau mus rau hauv lub qhov dej MOSFET , nws tau txais coupled los ntawm lub MOSFETs internalcapacitance rau lub rooj vag. Thaum uas tau tshwm sim, lub MOSFET tawg nyob rau hauv ib tug huab ntawm nplaim taws thiab cov pa taws dub.

Yog li ntawd, koj yuav ua li cas kuaj lub transistor hauv Circuit Court?

Hook qhov zoo txhuas txhuas los ntawm multimeter mus rau totheEMITTER (E) ntawm tus transistor . Hook qhov tsis zoo meterlead mus rau BASE (B) ntawm tus transistor . Rau qhov zoo NPN transistor , koj yuav tsum pom "OL" (OverLimit). Yog koj yog kuaj PNP transistor , lub meters yuav tsum showa voltage poob ntawm 0.45V thiab 0.9V.

Peb tuaj yeem kuaj transistor siv analog multimeter li cas?

Txuas lub hauv paus davhlau ya nyob twg transistor totheterminal cim qhov zoo (feem ntau xim liab) rau ntawm qhov multimeter . Txuas lub davhlau ya nyob twg uas cim tsis zoo los yog feem ntau (feem ntau xim dub) rau tus sau thiab ntsuas tiv thaiv. Nws yuav tsum nyeem qhib Circuit Court (yuav tsum muaj beadeflection rau PNP transistor ).
