Txheeb xyuas transistor: piav qhia ib qib zuj zus

IRFZ44 N

Qee lub sij hawm dhau los peb tau tshaj tawm cov lus qhia yuav ua li cas koj tuaj yeem ua tau xyuas cov capacitors. Tam sim no nws yog lwm tus tig cov khoom siv hluav taws xob tseem ceeb, qhov no zoo li cas. Ntawm no koj tuaj yeem pom li cas xyuas lub transistor piav qhia yooj yim heev thiab ib kauj ruam zuj zus, thiab koj tuaj yeem ua nws nrog cov cuab yeej zoo ib yam li cov multimeter.

lub transistors tau siv dav hauv ntau qhov hluav taws xob thiab hluav taws xob hluav taws xob rau kev tswj hwm nrog cov khoom siv hauv lub xeev no. Yog li ntawd, muab ntau npaum li cas lawv yog, koj yuav muaj tseeb hla cov xwm txheej uas koj yuav tsum txheeb xyuas lawv ...

Kuv xav tau dab tsi

yuav ua li cas xaiv multimeter, yuav ua li cas siv

Yog koj twb muaj zoo multimeter, lossis multimeter, qhov ntawd yog txhua yam koj xav tau los ntsuas koj lub transistor. Yog, qhov no Multimeter nws yuav tsum muaj txoj haujlwm los ntsuas cov transistors. Ntau tus niaj hnub digital multimeter muaj cov yam ntxwv no, txawm tias pheej yig. Nrog nws koj tuaj yeem ntsuas NPN lossis PNP bipolar transistors los txiav txim siab yog tias lawv puas.

Yog tias yog koj li xwm txheej, koj tsuas yog yuav tsum ntxig rau peb tus pin ntawm lub transistor hauv lub qhov (socket) ntawm lub multimeter uas tau qhia rau nws, thiab tso tus xaiv rau ntawm hFE txoj hauj lwm los ntsuas qhov nce. Yog li koj tuaj yeem tau txais kev nyeem ntawv thiab txheeb xyuas cov ntaub ntawv yog tias nws sib haum rau qhov nws yuav tsum muab.

Cov kauj ruam los tshuaj xyuas transistor bipolar

yuav ua li cas xaiv multimeter

Hmoov tsis zoo, tsis yog txhua lub multimeter muaj qhov yooj yim ntawd, thiab sim nws hauv txoj hauv kev ntau dua nrog txhua lub ntsuas cua koj yuav tsum ua nws txawv, nrog rau "Diode" kev ntsuas ua haujlwm.

  1. Thawj qhov yog tshem tawm transistor los ntawm Circuit kom tau txais kev nyeem ntawv zoo dua. Yog tias nws yog ib feem tseem tsis tau muab pov tseg, koj tuaj yeem txuag cov theem no.
  2. Kev xeem Base rau Issuer:
    1. Txuas qhov zoo (liab) cov hlau lead ntawm lub ntsuas cua mus rau lub hauv paus (B) ntawm lub transistor, thiab qhov tsis zoo (dub) ua rau tus emitter (E) ntawm transistor.
    2. Yog tias nws yog NPN transistor hauv qhov xwm txheej zoo, lub ntsuas yuav tsum qhia qhov poob qis ntawm 0.45V txog 0.9V.
    3. Nyob rau hauv rooj plaub ntawm PNP, lub npe OL (Tshaj Txwv) yuav tsum pom ntawm qhov screen.
  3. Kev xeem Base rau Collector:
    1. Txuas cov hlau lead zoo los ntawm lub ntsuas ntsuas mus rau lub hauv paus (B), thiab cov hlau lead tsis zoo rau tus sau (C) ntawm lub transistor.
    2. Yog tias nws yog NPN hauv qhov xwm txheej zoo, nws yuav qhia qhov poob qis ntawm 0.45v txog 0.9V.
    3. Yog tias ua PNP, ces OL yuav tshwm sim dua.
  4. Kev xeem Issuer rau Base:
    1. Txuas cov xov hlau zoo rau tus tso tawm (E) thiab xaim tsis zoo rau lub hauv paus (B).
    2. Yog tias nws yog NPN hauv qhov xwm txheej zoo nws yuav qhia OL lub sijhawm no.
    3. Nyob rau hauv rooj plaub ntawm PNP, qhov poob ntawm 0.45v thiab 0.9V yuav raug qhia.
  5. Kev xeem Collector rau Base:
    1. Txuas qhov zoo ntawm lub ntsuas ntsuas mus rau tus sau (C) thiab qhov tsis zoo rau lub hauv paus (B) ntawm transistor.
    2. Yog tias nws yog NPN, nws yuav tsum tshwm ntawm OL screen los qhia tias nws zoo.
    3. Nyob rau hauv rooj plaub ntawm PNP, qhov poob yuav tsum yog 0.45V thiab 0.9V yog tias ua tau.
  6. Kev xeem Collector rau Emitter:
    1. Txuas cov xaim liab mus rau tus neeg khaws khoom (C) thiab xaim dub mus rau tus tso tawm (E).
    2. Txawm hais tias nws yog NPN lossis PNP hauv qhov xwm txheej zoo, nws yuav qhia OL ntawm qhov screen.
    3. Yog tias koj thim rov qab cov xov hlau, qhov zoo ntawm tus xa tawm thiab qhov tsis zoo ntawm tus neeg sau khoom, ob qho tib si ntawm PNP thiab NPN, nws yuav tsum nyeem OL.

Yam kev ntsuas sib txawv ntawm qhov ntawd, yog ua kom raug, yuav qhia tias transistor tsis zoo. Koj kuj yuav tsum tau coj mus rau hauv tus account lwm yam, thiab qhov ntawd yog qhov kev ntsuas no tsuas yog kuaj xyuas yog tias lub transistor muaj qhov luv Circuit Court lossis lawv tau qhib, tab sis tsis yog lwm yam teeb meem. Yog li ntawd, txawm tias nws hla lawv, lub transistor yuav muaj qee qhov teeb meem uas tiv thaiv nws txoj haujlwm raug.

FET transistor cov

Yuav ua li cas thiaj yog a transistor FEB, thiab tsis yog bipolar ib, tom qab ntawd koj yuav tsum ua raws lwm cov kauj ruam no nrog koj cov digital lossis analog multimeter:

  1. Muab koj lub multimeter tso rau hauv qhov ntsuas kev ntsuas diode, zoo li ua ntej. Tom qab ntawd tso qhov dub (-) sojntsuam rau ntawm lub davhlau ya nyob twg, thiab liab (+) sojntsuam ntawm Lub Chaw Haujlwm Qhov Chaw. Qhov tshwm sim yuav tsum yog nyeem ntawm 513mv lossis zoo sib xws, nyob ntawm seb hom FET. Yog tias nyeem tsis tau, nws yuav qhib thiab yog tias nws qis heev nws yuav luv-ncig.
  2. Tsis tshem tawm cov lus qhia dub los ntawm lub qhov tso dej, tso cov lus qhia liab rau ntawm lub davhlau ya nyob twg Gate. Tam sim no qhov kev xeem yuav tsum tsis rov nyeem ib qho ntxiv. Yog tias nws pom ib qho txiaj ntsig ntawm qhov screen, tom qab ntawd yuav muaj qhov xau lossis luv Circuit Court.
  3. Muab cov taub tso rau hauv tus ciav dej, thiab ib qho dub yuav nyob hauv qhov dej. Qhov no yuav sim Drain-Source sib txuas los ntawm kev qhib nws thiab tau txais kev nyeem qis txog 0.82v. Txhawm rau deactivate transistor, nws peb lub davhlau ya nyob twg (DGS) yuav tsum luv-circuited, thiab nws yuav rov qab los ntawm lub xeev mus rau lub xeev tsis ua haujlwm.

Nrog rau qhov no, koj tuaj yeem sim FET-hom transistors, zoo li MOSFETs. Nco ntsoov kom muaj cov yam ntxwv zoo lossis cov ntaub ntawv ntawm cov no kom paub yog tias qhov txiaj ntsig koj tau txais yog txaus, vim nws txawv raws li hom transistor ...
