Matsayin MOSFETs a cikin da'irori

MOSFETstaka rawaa cikin sauyawa da'irorishine sarrafa kewayawa a kunne da kashewa da juyar da sigina.MOSFETs Za a iya raba shi zuwa kashi biyu: N-channel da P-channel.

A cikin N-channelMOSFETkewaye, BEEP fil yana da girma don ba da damar amsawar buzzer, kuma ƙananan don kashe buzzer.P-channel.MOSFETdon sarrafa wutar lantarki na module GPS a kunne da kashewa, GPS_PWR fil yana da ƙasa lokacin da aka kunna, GPS module ɗin ne wutar lantarki ta al'ada, kuma mai girma don sa na'urar GPS ta kashe wuta.

P-tasharMOSFETa cikin nau'in siliki na N-type akan yankin P + yana da biyu: magudanar ruwa da tushe. Wadannan sandunan guda biyu ba su da motsi ga junansu, lokacin da aka sami isasshen wutar lantarki mai inganci da aka kara wa tushen lokacin da aka kasa kasa, shimfidar siliki mai nau'in N-type da ke ƙasan ƙofar zai fito a matsayin nau'in P-inverse Layer, zuwa tashar da ke haɗa magudanar ruwa da tushe. . Canza wutar lantarki a ƙofar yana canza girman ramuka a cikin tashar, don haka canza juriya na tashar. Wannan ana kiransa transistor na haɓaka tasirin tasirin tashar P-tashar.
