Iwo mapini matatu eMOSFET, ndingaasiyanisa sei?

I. Pin Identification

Gedhi (G):Iyo inowanzonzi "G" kana inogona kuzivikanwa nekuyera kushorwa kune mamwe mapini maviri, sezvo gedhi rine yakakwira impedance mumamiriro asina simba uye haina kunyanya kubatana kune mamwe mapini maviri.

Kwakabva (S):Inowanzo kunzi "S" kana "S2", ndiyo pini iripo zvino uye inowanzobatanidzwa kune isina kunaka terminal yeMOSFET.

Dhonza (D):Kazhinji yakanyorwa kuti "D", ndiyo pini inoyerera uye yakabatana kune yakanaka terminal yedunhu rekunze.

II. Pin Basa

Gedhi (G):Ndiyo pini yakakosha inodzora kuchinjika kweMOSFET, nekudzora voltage pagedhi kuti idzore kubuda nekubuda kweMOSFET. Munzvimbo isina simba, iyo impedance yegedhi inowanzove yakakwira zvakanyanya, isina kukosha kwakabatana kune mamwe mapini maviri.

Kwakabva (S):ndiyo yazvino pini yekupinda uye inowanzobatanidzwa kune isina kunaka terminal yeMOSFET. MuNMOS, sosi inowanzoiswa pasi (GND); muPMOS, sosi inogona kunge yakabatana kune yakanaka inopa (VCC).

Dhonza (D):Ndiyo yazvino pini uye yakabatana kune yakanaka terminal yedunhu rekunze. MuNMOS, dhiraivha yakabatana kune yakanaka inopa (VCC) kana mutoro; muPMOS, dhiraini yakabatana pasi (GND) kana mutoro.

III. Kuyera nzira

Shandisa multimeter:

Seta iyo multimeter kune yakakodzera yekumisa kurongeka (semuenzaniso R x 1k).

Shandisa iyo isina kunaka terminal ye multimeter yakabatana kune chero electrode, imwe peni kuti ubate mapango maviri asara pamwe chete, kuyera kuramba kwayo.

Kana iyo miviri yakayerwa miyero yekupikisa inenge yakaenzana, iyo yakaipa peni yekubata gedhi (G), nekuti gedhi nemamwe mapini maviri pakati pekupikisa kazhinji yakakura kwazvo.

Tevere, iyo multimeter ichadaidzwa kuR × 1 giya, chinyoreso nhema chakabatana kune sosi (S), peni dzvuku yakabatana nedhiraivha (D), iyo yakayerwa kuramba kukosha kunofanirwa kuve mashoma ohms kune gumi nemaviri ohms, zvichiratidza. kuti tsime uye dhiraivha pakati chaiwo ezvinhu anogona conduction.

Tarisa kurongeka kwepini:

Kune maMOSFET ane yakatsanangurwa pini gadziriro (senge mamwe mafomu epasuru), nzvimbo uye basa repini yega yega inogona kutariswa nekutarisa pini kuronga dhiyagiramu kana dheteti.

IV. Zvekungwaririra

Mhando dzakasiyana dzeMOSFET dzinogona kunge dziine mapini akasiyana marongero uye mamaki, saka zvakanakisa kubvunza dhetabheti kana pasuru kudhirowa kweiyo chaiyo modhi usati washandisa.

Pakuyera nekubatanidza mapini, iva nechokwadi chekuteerera kune static magetsi kudzivirira kudzivirira kukuvadza MOSFET.

MOSFETs midziyo inodzorwa nevoltage ine kukurumidza kushandura kumhanya, asi mune inoshanda maapplication zvichiri kufanira kutarisisa dhizaini nekugadzirisa kwedhiraivha yedhiraivha kuti ive nechokwadi chekuti MOSFET inogona kushanda nemazvo uye nekuvimbika.

Muchidimbu, mapini matatu eMOSFET anogona kunyatsosiyaniswa nenzira dzakasiyana senge pini yekuzivikanwa, pini basa uye nzira dzekuyera.
