Nibihe bipimo nakagombye kwitondera muguhitamo Triode na MOSFET?

Ibikoresho bya elegitoronike bifite ibipimo byamashanyarazi, kandi ni ngombwa gusiga intera ihagije kubikoresho bya elegitoronike muguhitamo ubwoko kugirango hamenyekane ituze hamwe nigihe kirekire cyibikoresho bya elegitoroniki. Ibikurikira menyekanisha muri make uburyo bwo guhitamo Triode na MOSFET.

Triode nigikoresho kigenzurwa nigitemba, MOSFET nigikoresho kigenzurwa na voltage, hari ibyo bihuriyeho byombi, muguhitamo gukenera gutekereza kuri voltage ihagaze, ikigezweho nibindi bipimo.

 

1, ukurikije uburyo ntarengwa bwo kwihanganira guhitamo voltage

Ikusanyirizo rya Triode C na emitter E irashobora kwihanganira voltage ntarengwa hagati yumuyobozi mukuru wa V (BR), voltage iri hagati ya CE mugihe ikora ntishobora kurenga agaciro kagenwe, bitabaye ibyo Triode ikangirika burundu.

Umuvuduko ntarengwa nawo ubaho hagati yumuyoboro D nisoko S ya MOSFET mugihe cyo gukoresha, na voltage hejuru ya DS mugihe ikora ntigomba kurenza agaciro kagenwe. Mubisanzwe nukuvuga, voltage ihanganira agaciro kaBYINSHIni hejuru cyane ya Triode.

 

2, ubushobozi burenze urugero

Triode ifite ibipimo bya ICM, ni ukuvuga, gukusanya ubushobozi burenze urugero, kandi ubushobozi burenze urugero bwa MOSFET bugaragazwa mubijyanye nindangamuntu. Iyo ibikorwa byubu, ibyanyuze muri Triode / MOSFET ntibishobora kurenza agaciro kagenwe, bitabaye ibyo igikoresho kizatwikwa.

Urebye imikorere ihamye, intera ya 30% -50% cyangwa irenga iremewe muri rusange.

3、Ubushyuhe bwo gukora

Ubucuruzi-urwego rwubucuruzi: urwego rusange rwa 0 kugeza kuri +70 ℃;

Inganda zo mu rwego rwinganda: urwego rusange -40 kugeza +85 ℃;

Imipira yo mu rwego rwa gisirikare: urwego rusange -55 ℃ kugeza +150 ℃;

Mugihe uhitamo MOSFET, hitamo chip ikwiranye nigihe cyo gukoresha ibicuruzwa.

 

4, ukurikije guhitamo guhinduranya inshuro

Triode naBYINSHIufite ibipimo byo guhinduranya inshuro / igihe cyo gusubiza. Niba ikoreshejwe mumirongo myinshi yumurongo, igihe cyo gusubiza umuyoboro woguhindura kigomba gutekerezwa kugirango cyuzuze ibisabwa.

 

5、Ibindi byatoranijwe

Kurugero, on-resistance Ron ibipimo bya MOSFET, VTH ifunguye kuri voltage yaBYINSHI, n'ibindi.

 

Umuntu wese muguhitamo MOSFET, urashobora guhuza ingingo zavuzwe haruguru kugirango uhitemo.
