Ni irihe tandukaniro riri hagati ya MOSFETs na Triode iyo ikoreshejwe nka switch?

MOSFET na Triode nibintu bisanzwe bikoreshwa muburyo bwa elegitoronike, byombi birashobora gukoreshwa nka elegitoronike, ariko kandi mubihe byinshi byo guhanahana ikoreshwa rya switch, nkuburyo bwo gukoresha,BYINSHIna Triode bifite byinshi bisa, hari nahantu hatandukanye, none byombi bigomba kuba uburyo bwo guhitamo?

 

Triode ifite ubwoko bwa NPN nubwoko bwa PNP.MOSFET nayo ifite N-umuyoboro na P-umuyoboro. Amapine atatu ya MOSFET ni irembo G, imiyoboro D nisoko S, naho pin eshatu za Triode ni base B, umuterankunga C na emitter E. Ni irihe tandukaniro riri hagati ya MOSFET na Triode?

 

 

N-MOSFET na NPN Triode ikoreshwa nkihame ryo guhinduranya

 

(1) Uburyo butandukanye bwo kugenzura

Triode ni ubwoko bwubwoko bugenzura, kandi MOSFET nigice cyo kugenzura voltage, Triode kumurongo winjiza ibisabwa byuruhande rwigenzura ni bike, mubisanzwe 0.4V kugeza 0.6V cyangwa byinshi birashobora kugerwaho Triode kuri, muguhindura imipaka shingiro Kurwanya kurubu birashobora guhindura ishingiro ryibanze. MOSFET iyobowe na voltage, voltage isabwa kugirango ikorwe mubisanzwe iba hafi 4V kugeza 10V, kandi iyo kwiyuzuza bigeze, voltage isabwa ni 6V kugeza 10V. Mugucunga ibihe bya voltage yo hasi, gukoresha muri rusange Triode nka switch, cyangwa Triode nka buffer igenzura MOSFET, nka microcontrollers, DSP, PowerPC hamwe nibindi bitunganyiriza I / O icyambu cya porte ni gito, gusa 3.3V cyangwa 2.5V , muri rusange ntabwo bizagenzura nezaBYINSHI, voltage yo hasi, MOSFET ntishobora kuba imiyoboro cyangwa kurwanya imbere yimikoreshereze yimbere yimbere Muri iki gihe, kugenzura Triode bisanzwe bikoreshwa.

 

(2) Inzitizi zitandukanye zo kwinjiza

Triode yinjiza impedance ni nto, MOSFET yinjiza impedance nini, capacitance ihuza iratandukanye, ubushobozi bwa Triode ihuza nini kuruta MOSFET, ibikorwa bikurikije MOSFET kugirango byihute kuruta Triode;BYINSHImu gutuza kwibyiza, ni umuyoboro mwinshi, urusaku ruto, ubushyuhe bwumuriro nibyiza.

MOSFET irwanya imbere ni nto cyane, kandi Triode igabanuka kuri leta ya voltage igabanuka hafi ya, mugihe gito gito, muri rusange ukoreshe Triode, kandi ukoreshe MOSFET nubwo kurwanya imbere ari bito cyane, ariko ikigezweho ni kinini, igitonyanga cya voltage nacyo nini cyane.
