Puas yog txhua tus NPN cov contistors tib yam?

1, qauv sib txawv
Firstly, kev hais lus hais, Txawm hais tias txhua tus qauv NPN ya ua ke, yuav muaj qhov sib txawv, tob tob, thiab lwm yam ntawm cov neeg sib txawv ntawm NPNN. Cov kev sib txawv no yuav cuam tshuam ncaj qha rau cov yam ntxwv hluav taws xob ncaj qha rau cov xeeb ceem uas hluav taws xob, xws li tam sim no lub zog hluav taws xob, kev ua haujlwm hluav taws xob ntau, hloov ceev, thiab lwm yam.
2, kev sib txawv
Kev ua yeeb yam sib txawv yog ib qho tseem ceeb tshaj plaws ntawm NPN chaw tshaj tawm. Txawv NPN transistors yuav txawv heev hauv kev ua tsis tau xws li tam sim no borificate factor, cov lus tawm tsis kam, thiab teb tau ntau zaus. Piv txwv li, siab zaus NPNN cov transistors muaj kev ua tau zoo dua nyob rau hauv cov chaw sib txuas lus loj li wireless sib txuas lus thiab RF amplification; Tsawg zaus NPN transistors tej zaum yuav muaj ntau dua cov amplification thiab qis dua cov suab nrov, ua rau nws haum ntau rau cov kev siv xws li audio amplification thiab teeb liab ua.
3, thov sib txawv
Vim yog kev ua tau zoo sib txawv, cov qauv sib txawv ntawm NPN cov transistors kuj muaj lawv tus kheej hauv daim ntawv thov. Hauv kev voj voog ampification, kev ua yeeb yam zoo NPN tuaj yeem muab kev xaiv ntau dua thiab txo qis kev xaiv rau cov khoom siv xws li audio amplifiers thiab rf amplifiers; Hauv kev hloov pauv hloov pauv, cov lus teb ceev nrn tuaj yeem tswj tau zoo dua ntawm / tawm ntawm tam sim no, thiab tau siv dav hauv teb xws li lub cev muaj zog tswj thiab relay tsav. Ntxiv rau, nrog kev txhim kho cov tshuab hluav taws xob ntxiv, NPN cov chaw nyob hauv ntau cov teb xws li microprocess, digital kev tswj hwm, thiab lwm yam.
4, sib txawv hauv kev tsim cov txheej txheem
Cov txheej txheem tsim khoom kuj tseem yog ib qho ntawm cov tseem ceeb uas ua rau sib txawv ntawm NPN nyuam qhuav. Cov txheej txheem tsim kev sib txawv yuav ua rau sib txawv hauv kev sib txawv hauv doping tej khaub ncaws, thiab lwm yam ntawm cov transistors, uas nyob rau hauv lem cuam tshuam rau lawv kev ua tau zoo thiab ntseeg tau. Nrog kev nce qib nro ntawm semiconductor thev naus laus zis, xws li cov txheej txheem kev loj hlob ntawm cov khoom siv tshiab thiab kuj nce qib ntawm cov khoom hluav taws xob.
