YUAV UA LI CAS YUAV TSHUAJ KOV SWITCH siv tsuas yog ib tus MOSFET TRANSISTOR

Muaj ntau txoj hauv kev, MOSFETs zoo dua li cov transistors niaj hnub thiab niaj hnub no transistor project

peb yuav qhia yuav ua li cas thiaj hloov tau qhov kov yooj yim uas yuav hloov qhov hloov pauv ib txwm nrog kev pab los ntawm

ib mosfet transistor.

Kev hloov pauv yog hom hloov pauv uas tsuas yog yuav tsum tau kov los ntawm ib qho khoom siv los ua haujlwm. Nws tau siv rau hauv ntau lub teeb thiab cov phab ntsa hloov pauv uas muaj cov hlau sab nrauv ntxiv rau hauv cov chaw siv computer. Lub vijtsam kov suav nrog ib qho ntawm cov hloov pauv ntawm lub vijtsam.

Rau qhov haujlwm no koj yuav xav tau:

mosfet

9 v pin

12v coj sawb lossis 12v teeb

xov hlau

Kauj Ruam 1: Mosfet Transistor

Cov hlau – oxide – semiconductor field-effect transistor (MOSFET, MOS-FET, lossis MOS FET) yog ib hom kev cuam tshuam kev hloov pauv hloov chaw (FET). Nws muaj lub qhov rooj thaiv, nws qhov hluav taws xob txiav txim siab qhov ua tau zoo ntawm lub cuab yeej. Lub peev xwm no los hloov kev coj ua nrog tus nqi siv hluav taws xob tuaj yeem siv rau kev hloov pauv lossis hloov pauv cov cim hluav taws xob. Cov hlau – insulator – semiconductor field-effect transistor lossis MISFET yog lo lus yuav luag zoo ib yam nrog MOSFET. Lwm lub ntsiab lus yog IGFET rau insulated-gate field-effect transistor.

Lub hauv paus ntsiab lus tseem ceeb ntawm kev hloov pauv hloov pauv hauv thaj av yog thawj daim ntawv lees paub los ntawm Julius Edgar Lilienfeld xyoo 1925.

Qhov txiaj ntsig tseem ceeb ntawm MOSFET yog qhov nws xav tau yuav luag tsis muaj cov tswv yim tam sim no los tswj cov thauj khoom tam sim no thaum piv nrog bipolar transistors. Hauv "kev txhim kho hom" MOSFET, qhov ntsuas hluav taws xob tau siv rau lub qhov rooj davhlau ya nyob twg nce kev ua haujlwm ntawm lub cuab yeej. Hauv "hom depletion" transistors, qhov hluav taws xob tau thov ntawm lub qhov rooj txo qhov kev coj ua

Kauj Ruam 2: Mosfet Transistor Projects

Tam sim no peb yuav txuas mus rau qhov txuas ntawm cov xov hlau mus rau 3 lub davhlau ya nyob twg ntawm mosfet tsuas yog kom yooj yim thaum peb yuav ua qhov txuas rau peb hloov thiab muab tso rau hauv rooj plaub me me rau cov phiaj xwm yav tom ntej.

Mosfet siv hauv txoj haujlwm no yog IRF z44n ib qho transistor ntau heev

Raws li IRFZ44 cov ntawv no yog lub zog thib peb MOSFET uas muab kev sib xyaw zoo tshaj plaws ntawm kev hloov pauv sai, ruggedized ntaus ntawv tsim, tsis muaj kev tiv thaiv thiab tus nqi tsim nyog. Cov pob TO-220AB yog thoob ntiaj teb nyiam rau kev lag luam-kev lag luam kev siv hluav taws xob nyob rau theem kwv yees li 50 W. Kev tiv thaiv cua sov tsawg thiab cov nqi qis ntawm TO-220AB pab txhawb rau nws qhov kev lees paub thoob plaws hauv kev lag luam. Kev qhia tshwj xeeb: VDSS Siab Tshaj: 55VMaximum Dej ntws tam sim no: 49A ntawm 250CRDS (ntawm): 17.5mOhmsMuaj zog tshaj tawm: 50WPackage: TO-220

Kauj Ruam 3: Mosfet Hloov Daim Duab

Koj muaj daim duab qhia yuav ua li cas txuas cov xov hlau yog yooj yim heev tsuas yog txuas lub load (qhov no yog 12v qhov muag teeb)

mus rau + lub davhlau ya nyob twg ntawm 9v lub roj teeb thiab lub hauv paus ntawm lub nra rau nruab nrab tus pin ntawm mosfet. Qhov -lub davhlau ya nyob twg tsis zoo ntawm lub roj teeb mus rau sab xis kawg lub davhlau ya nyob twg ntawm mosfet. Thiab qhov ntawd yog nws koj muaj lub tsev kawm ntawv qub hloov.

Txhawm rau qhib qhov hloov pauv koj yuav tsum muab koj tus ntiv tes tso rau sab laug kawg ntawm lub davhlau ya nyob twg ntawm mosfet thiab +lub davhlau ya nyob twg ntawm lub roj teeb.

Txhawm rau tshem tawm qhov hloov pauv koj muab koj tus ntiv tes tso rau sab laug kawg ntawm lub davhlau ya nyob twg ntawm mosfet thiab sab xis kawg ntawm lub davhlau ya nyob twg ntawm mosfet lossis - davhlau ya nyob twg ntawm lub roj teeb.

Kauj Ruam 4: Diy Kov Hloov Hauv Lub Thawv

Tam sim no tsuas yog siv koj lub tswv yim thiab ua lub thawv/lub thawv tso rau tag nrho cov xov hlau thiab mosfet transistor koj tuaj yeem siv cov yas yas qub uas koj tsis siv ntxiv lawm hauv cov vis dis aus kuv tau siv lub qub zog pheej yig lub txhab nyiaj ntim khoom

tab sis koj tuaj yeem siv tic-tac rooj plaub qub tes pleev (Nivea) thiab ntau yam ntxiv.

Txhua qhov zoo tshaj plaws thiab siv koj lub tswv yim!
