Kuv yuav tsum xyuam xim rau dab tsi thaum xaiv Triode thiab MOSFET?

Cov khoom siv hluav taws xob muaj cov khoom siv hluav taws xob tsis zoo, thiab nws yog ib qho tseem ceeb uas yuav tsum tau tawm ntawm cov npoo txaus rau cov khoom siv hluav taws xob thaum xaiv hom kom muaj kev ruaj ntseg thiab kev ua haujlwm ntev ntawm cov khoom siv hluav taws xob. Tom ntej no luv luv qhia txog Triode thiab MOSFET txoj kev xaiv.

Triode yog cov khoom siv khiav-tswj, MOSFET yog cov khoom siv hluav taws xob tswj hluav taws xob, muaj qhov zoo sib xws ntawm ob, hauv kev xaiv ntawm qhov yuav tsum tau xav txog qhov tiv taus voltage, tam sim no thiab lwm yam tsis.

 

1, raws li qhov siab tshaj plaws tiv thaiv voltage xaiv

Triode collector C thiab emitter E tuaj yeem tiv taus qhov siab tshaj plaws ntawm qhov ntsuas V (BR) CEO, qhov hluav taws xob ntawm CE thaum lub sijhawm ua haujlwm yuav tsum tsis pub tshaj tus nqi teev, txwv tsis pub Triode yuav raug puas tsuaj mus tas li.

Qhov siab tshaj plaws voltage kuj tseem muaj nyob nruab nrab ntawm qhov ntws D thiab qhov chaw S ntawm MOSFET thaum siv, thiab qhov hluav taws xob hla DS thaum ua haujlwm yuav tsum tsis pub tshaj tus nqi teev. Feem ntau hais lus, qhov voltage withstand nqi ntawmMOSFETyog siab tshaj Triode.

 

2, lub siab tshaj plaws overcurrent muaj peev xwm

Triode muaj ICM parameter, piv txwv li, muaj peev xwm sau overcurrent, thiab lub peev xwm overcurrent ntawm MOSFET yog qhia nyob rau hauv cov nqe lus ntawm ID. Thaum lub sijhawm ua haujlwm tam sim no, qhov tam sim no ntws los ntawm Triode / MOSFET tsis tuaj yeem tshaj tus nqi teev, txwv tsis pub lub cuab yeej yuav raug hlawv.

Xav txog qhov kev ua haujlwm ruaj khov, cov npoo ntawm 30% -50% lossis ntau dua yog feem ntau tso cai.

3,Ua haujlwm kub

Kev lag luam-qib chips: dav dav ntawm 0 txog +70 ℃;

Industrial-qib chips: dav dav ntawm -40 txog +85 ℃;

Tub rog qib chips: dav dav ntawm -55 ℃ to +150 ℃;

Thaum xaiv MOSFET, xaiv cov nti tsim nyog raws li cov khoom siv sijhawm.

 

4, raws li kev xaiv hloov zaus

Ob leeg Triode thiabMOSFETmuaj cov kev hloov pauv zaus / lub sijhawm teb. Yog tias siv nyob rau hauv high-frequency circuits, lub sij hawm teb ntawm lub switching tube yuav tsum tau txiav txim siab kom ua tau raws li cov kev cai ntawm kev siv.

 

5,Lwm yam kev xaiv

Piv txwv li, nyob rau-kuj Ron parameter ntawm MOSFET, VTH tig-on voltage ntawm lubMOSFET, thiab lwm yam.

 

Txhua tus neeg hauv MOSFET xaiv, koj tuaj yeem muab cov ntsiab lus saum toj no rau kev xaiv.
