MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) yana da sanduna uku waɗanda sune:
Kofa:G, Ƙofar MOSFET daidai yake da tushe na transistor bipolar kuma ana amfani dashi don sarrafa sarrafawa da yankewa MOSFET. A MOSFETs, ƙarfin lantarki na ƙofar (Vgs) yana ƙayyade ko an samar da tashar sarrafawa tsakanin tushen da magudanar ruwa, da kuma faɗin tashar sarrafawa. Ƙofar an yi ta ne da abubuwa kamar ƙarfe, polysilicon, da sauransu, kuma an kewaye shi da wani rufin da ke rufe (yawanci silicon dioxide) don hana halin yanzu shiga ko fita kai tsaye.
Source:S, tushen MOSFET yayi daidai da emitter na transistor bipolar kuma shine inda halin yanzu ke gudana. A cikin MOSFETs na tashar N-channel, yawanci ana haɗa tushen zuwa madaidaicin madaidaicin (ko ƙasa) na wutar lantarki, yayin da a cikin MOSFET na P-tashar, tushen yana haɗa da ingantaccen tashar wutar lantarki. Madogararsa na ɗaya daga cikin mahimman sassan da ke samar da tashar gudanarwa, wanda ke aika electrons (N-channel) ko ramuka (P-channel) zuwa magudanar ruwa lokacin da ƙarfin gate ya isa.
Ruwa:D, magudanar MOSFET yayi daidai da mai tara transistor bipolar kuma shine inda na yanzu ke gudana a ciki. Magudanar yawanci ana haɗawa da kaya kuma tana aiki azaman fitarwa na yanzu a cikin kewaye. A cikin MOSFET, magudanar ruwa ita ce ƙarshen tashar gudanarwa, kuma lokacin da wutar lantarki ta ƙofar ke sarrafa samar da tashar gudanarwa tsakanin tushen da magudanar ruwa, halin yanzu na iya gudana daga tushen ta hanyar tashar sarrafawa zuwa magudanar ruwa.
A takaice dai, ana amfani da kofar MOSFET wajen sarrafa wuta da kashewa, inda ake fitar da ruwa daga waje, kuma magudanar ruwa ita ce inda na yanzu ke kwarara. .
