Pali mitundu yambiri ya magawo akuluakulu aMOSFET, yomwe ili ndi ma DC apano, magawo apano a AC ndi malire, koma kugwiritsa ntchito pafupipafupi kumangofunika kusamala magawo oyambira awa: machulukitsidwe a gwero lotayikira pano IDSS kutsina voteji Kumwamba, transconductance gm, kutayikira gwero lamagetsi BUDS, Kutayika kwakukulu kwa mphamvu ya PDSM ndi gwero lalikulu la IDSM lamakono.
1.Saturated kutayikira gwero panopa
IDSS yodzaza ndi gwero lapano la IDSS imatanthawuza kukhetsa komwe kumachokera pamagetsi a chipata UGS = 0 pamphambano kapena mtundu wocheperako wa chipata cha MOSFET.
2. Chotsitsa chamagetsi
Pinch-off voltage UP imatanthawuza mphamvu yamagetsi ogwiritsira ntchito pachipata pamphambano kapena mtundu wa depletion wosanjikiza chipata.MOSFETzomwe zimapangitsa kuti drain-source iwonongeke. Dziwani zomwe IDSS ndi UP zimatanthauza.
3, Yatsani magetsi
Mphamvu yamagetsi ya UT imatanthawuza mphamvu yamagetsi ogwiritsira ntchito pachipata mu MOSFET yolumikizidwa ndi chipata kuti cholumikizira cholumikizira chitseko chiziyatsidwa. Dziwani zomwe UT ikutanthauza.
4.Malangizo odutsa
Transguide gm imagwiritsidwa ntchito kuwonetsa kuthekera kwa chipata gwero lamagetsi kuwongolera kukhetsa kwapano, ndiye kuti, chiŵerengero chapakati pa kusintha kwa kukhetsa kwapano ndi kusintha kwa magetsi a chipata.
5, Kutayika kwakukulu kwa mphamvu zotulutsar
Mphamvu yotulutsa yotayika kwambiri imakhalanso ya malire, zomwe zikutanthauza kuti mphamvu yotayika kwambiri yotayika yomwe imatha kuloledwa ikamagwira ntchito.MOSFETndi zabwinobwino komanso zosakhudzidwa. Tikamagwiritsa ntchito MOSFET, kutayika kwake kogwira ntchito kuyenera kukhala kotsika kuposa PDSM ndi mtengo wake.
6, Maximum kutayikira gwero panopa
The maximum drain-source current, IDSM, imakhalanso yochepetsera malire, kutanthauza kuti pakali pano amaloledwa kudutsa pakati pa kukhetsa ndi gwero la MOSFET panthawi ya ntchito yabwino, ndipo sayenera kupitirira pamene MOSFET ikugwira ntchito.
olukey wakhala m'modzi mwa othandizira omwe akukula mwachangu ku Asia kudzera mukutukuka kwa msika komanso kuphatikiza kothandiza kwa zinthu, ndipo kukhala wothandizira wofunika kwambiri padziko lonse lapansi ndicho cholinga chofala cha olukey.
