MOSFET Operating Characteristics

Muchokwadi, kubva pazita, iro simba MOSFET nderekuti rinogona kushanda zvakare kana yakabuda ikozvino yakakura, MOSFET classification yakakamurwa mumhando dzakawanda, izvo zvakatenderedza maitiro ekushandiswa kwesimba isu tinogona kukamurwa kuita kusimudzira uye kupera kwemhando, kana zvinoenderana nechiteshi chekusarudza mazwi anogona kukamurwa kuita N-chiteshi mhando uye P-chiteshi mhando.
MOSFETs anonyanya kushandiswa sesystem switch mumasisitimu anoburitsa simba. Kana tikawedzera imwe voltage pakati pegedhi uye kunobva N-channel MOSFET, inobatidza simba rayo switch. Kamwe chinja chemagetsi chabatidzwa, ikozvino inoyerera kuburikidza nemagetsi switch kubva padhiraini kuenda kune kwainosuka. Pane kupokana kwemukati pakati pekudonhedza uye kunobva, iyo yatinowanzo daidza iyo on-resistor RDS(ON). Izvo zvinofanirwa kuve pachena kuti gedhi reMOSFET chairo rakakwirira hunhu impedance terminal, saka isu tinofanirwa kuwedzera imwe voltage kugedhi. Kana iyo voltage pakati pechitubu negedhi iri zero, switch yemagetsi inodzima uye kuyerera kwazvino kunopera zvinoenderana nemudziyo. Kunyangwe mudziyo wakadzimwa kwenguva yakareba, pachine chidiki chidiki chazvino, chinodaidzwa kuti leakage ikozvino IDSS.
NokutiMOSFETsndechimwe chezvinhu zvakakosha zvegadziriro yemagetsi, kusarudza iyo MOSFET yakakodzera inoita basa rakakosha mukubudirira kwechirongwa chese chekugadzira. Nekugona chete mhando dzeMOSFET uye hunhu hwavo hwakakosha, vagadziri vanogona kusarudza iyo chaiyo MOSFET yeimwe dhizaini.

Simba MOSFET ikirasi inowanzo shandiswa yemagetsi emagetsi, zita rakazara reChinese ndere - metal oxide semiconductor field effect chubhu. Iyo ndeyechigadzirwa chemagetsi chinobuda, chinonyanya kuumbwa nesimbi, oxide uye semiconductor zvinhu. Saka simba racho chiiMOSFET?

Kuburikidza nekusimudzira kwemusika uye kubatanidza zviwanikwa zvinobudirira,olukeychave chimwe chevamiriri vakatanhamara uye vanokura nekukurumidza muAsia, uye ndicho chinangwa chakajairwa naLukey kuva mumiriri akakosha kwazvo pasi rose. Kwemakore, olukey kambani kukweretesa kupona, kuomerera kune "mhando yekutanga, sevhisi kutanga" chinangwa uye mazhinji epamusoro-tekinoroji mabhizinesi kumba nekune dzimwe nyika, iyo yekutanga fekitori yekumisikidza hukama hwakanaka hwekushanda, nemakore mazhinji ehunyanzvi ruzivo mukugovera. , nechikwereti chakanaka, sevhisi yakanaka, uye yakawana kuvimba nekutsigirwa kwakapararira.
