Lipini tse tharo tsa MOSFET, nka li arola joang?

I. Pin Identification

Heke (G):Hangata e ngotsoe "G" kapa e ka khetholloa ka ho lekanya ho hanyetsa lithapo tse ling tse peli, kaha heke e na le ts'oaetso e phahameng haholo sebakeng se se nang matla 'me ha e amane haholo le lithapo tse ling tse peli.

Mohloli (S):Hangata e ngotsoe "S" kapa "S2", ke phini ea hona joale ea ho kena 'me hangata e hokahane le theminale e fosahetseng ea MOSFET.

Khala (D):Hangata e ngotsoe "D", ke pinana ea hona joale ea phallo 'me e hokahane le terminal e ntle ea potoloho ea kantle.

II. Mosebetsi oa Pin

Heke (G):Ke phini ea senotlolo e laolang ho fetoha ha MOSFET, ka ho laola motlakase hekeng ho laola ho kena le ho tsoa ha MOSFET. Boemong bo se nang matla, ho thibela heke ka kakaretso ho phahame haholo, ho se na khokahanyo ea bohlokoa ho lithapo tse ling tse peli.

Mohloli (S):ke phini ea hona joale ea ho kena 'me hangata e hokahane le terminal e fosahetseng ea MOSFET. Ho NMOS, mohloli hangata o thehiloe (GND); ho PMOS, mohloli o ka hokahanngoa le phepelo e ntle (VCC).

Khala (D):Ke pin ea hona joale 'me e hokahane le terminal e ntle ea potoloho ea kantle. Ho NMOS, drain e hokahane le phepelo e ntle (VCC) kapa mojaro; ho PMOS, drain e hokahane le fatše (GND) kapa mojaro.

III. Mekhoa ea ho lekanya

Sebelisa multimeter:

Beha multimeter ho boemo bo nepahetseng ba khanyetso (mohlala, R x 1k).

Sebelisa terminal e mpe ea multimeter e hokahantsoeng le eleketrode efe kapa efe, pene e 'ngoe ho ikopanya le lipalo tse peli tse setseng ka ho latellana, ho lekanya ho hanyetsa ha eona.

Haeba litekanyetso tse peli tse lekantsoeng tsa ho hanyetsa li batla li lekana, pene e mpe ea ho kopana le heke (G), hobane heke le lithapo tse ling tse peli pakeng tsa ho hanyetsa hangata li kholo haholo.

Ka mor'a moo, multimeter e tla letsetsoa ho R × 1 gear, pene e ntšo e hokahantsoeng mohloling (S), pene e khubelu e hokahantsoeng le drainage (D), boleng ba ho hanyetsa bo lekantsoeng e lokela ho ba li-ohms tse 'maloa ho isa ho tse ngata tsa ohms, e bontšang. hore mohloli le drain pakeng tsa maemo a itseng e ka ba conduction.

Ela hloko tlhophiso ea pin:

Bakeng sa li-MOSFET tse nang le tlhophiso ea phini e hlalositsoeng hantle (joalo ka liforomo tse ling tsa sephutheloana), sebaka le mosebetsi oa pinana ka 'ngoe li ka khethoa ka ho sheba setšoantšo sa tlhophiso ea phini kapa database.

IV. Mehato ya tlhokomelo

Mefuta e fapaneng ea li-MOSFET e kanna ea ba le litlhophiso le matšoao a fapaneng, ka hona ho molemo ho sheba setlankana kapa setšoantšo sa sephutheloana sa mofuta o itseng pele o sebelisoa.

Ha u lekanya le ho hokahanya lithakhisa, etsa bonnete ba hore u ela hloko tšireletso ea motlakase o tsitsitseng ho qoba ho senya MOSFET.

Li-MOSFET ke lisebelisoa tse laoloang ke motlakase tse nang le lebelo la ho fetoha ka potlako, empa lits'ebetsong tse sebetsang ho ntse ho hlokahala ho ela hloko moralo le ntlafatso ea potoloho ea koloi ho netefatsa hore MOSFET e khona ho sebetsa hantle le ka ts'epo.

Ka bokhuts'oane, lithakhisa tse tharo tsa MOSFET li ka khetholloa ka nepo ka mekhoa e fapaneng joalo ka boitsebahatso ba phini, tšebetso ea phini le mekhoa ea ho metha.
