Amapine atatu ya MOSFET, nababwira nte gutandukana?

I. Kumenyekanisha Pin

Irembo (G):Ubusanzwe byanditseho "G" cyangwa birashobora kumenyekana mugupima ukurwanya kurindi pine ebyiri, kuko irembo rifite inzitizi ndende cyane muri reta idafite ingufu kandi ntaho ihuriye cyane nizindi pin ebyiri.

Inkomoko (S)：Mubisanzwe byanditseho "S" cyangwa "S2", ni pin yinjira muri iki gihe kandi isanzwe ihujwe na terefone mbi ya MOSFET.

Drain (D)：Mubisanzwe byanditseho "D", ni pine igezweho kandi ihujwe na terminal nziza yumuzingi wo hanze.

II. Imikorere ya Pin

Irembo (G):Nibipapuro byingenzi bigenzura guhinduranya MOSFET, mugucunga voltage kumuryango kugirango igenzure kuri MOSFET. Muburyo budafite imbaraga, inzitizi y irembo muri rusange ni ndende cyane, ntaho ihuriye cyane nizindi pin ebyiri.

Inkomoko (S)：ni ikigezweho cyinjira pin kandi mubisanzwe ihujwe na terefone mbi ya MOSFET. Muri NMOS, isoko isanzwe iba ishingiye (GND); muri PMOS, isoko irashobora guhuzwa nibintu byiza (VCC).

Drain (D)：Nibisanzwe hanze pin kandi ihujwe na terminal nziza yumuzingi wo hanze. Muri NMOS, imiyoboro ihujwe no gutanga ibintu byiza (VCC) cyangwa umutwaro; muri PMOS, imiyoboro ihujwe nubutaka (GND) cyangwa umutwaro.

III. Uburyo bwo gupima

Koresha multimeter:

Shyira multimeter muburyo bukwiye bwo guhangana (urugero R x 1k).

Koresha itumanaho ribi rya multimeter ihujwe na electrode iyariyo yose, irindi karamu kugirango uhuze inkingi ebyiri zisigaye nazo, kugirango upime guhangana.

Niba indangagaciro zibiri zapimwe zingana zingana, ikaramu itari nziza ihuza irembo (G), kubera ko irembo nizindi pine ebyiri hagati yuburwanya ari nini cyane.

Ibikurikira, multimeter izahamagarwa kuri R × 1 ibikoresho, ikaramu yumukara ihujwe ninkomoko (S), ikaramu itukura ihujwe numuyoboro (D), agaciro kapimye gupimwa kugomba kuba oms nkeya kugeza kuri mirongo ya ohm, byerekana ko isoko namazi hagati yimiterere yihariye irashobora kuba imiyoboro.

Itegereze pin:

Kuri MOSFETs hamwe na pin isobanuwe neza (nkuburyo bumwe bwo gupakira), ahantu hamwe nibikorwa bya buri pin birashobora kugenwa no kureba igishushanyo mbonera cya pin cyangwa datasheet.

IV. Kwirinda

Ubwoko butandukanye bwa MOSFETs bushobora kugira gahunda ya pin itandukanye hamwe nibimenyetso, nibyiza rero kubaza datasheet cyangwa igicapo cyo gushushanya kubintu byihariye mbere yo gukoresha.

Mugihe cyo gupima no guhuza amapine, menya neza ko wirinda amashanyarazi ahamye kugirango wirinde kwangiza MOSFET.

MOSFETs ni ibikoresho bigenzurwa na voltage ifite umuvuduko wo guhinduranya byihuse, ariko mubikorwa bifatika biracyakenewe kwitondera igishushanyo mbonera no gutezimbere umuzenguruko wa drayike kugirango MOSFET ikore neza kandi yizewe.

Muncamake, amapine atatu ya MOSFET arashobora gutandukanywa neza nuburyo butandukanye nko kumenya pin, imikorere ya pin nuburyo bwo gupima.
