Feem ntau siv SMD MOSFET pob pinout cov ntsiab lus

Lub luag haujlwm ntawm MOSFETs yog dab tsi?

MOSFETs ua lub luag haujlwm hauv kev tswj qhov hluav taws xob ntawm tag nrho cov khoom siv hluav taws xob. Tam sim no, tsis muaj ntau cov MOSFETs siv rau ntawm lub rooj tsavxwm, feem ntau yog hais txog 10. Qhov laj thawj tseem ceeb yog vim li cas feem ntau ntawm MOSFETs tau muab tso rau hauv IC nti. Txij li lub luag haujlwm tseem ceeb ntawm MOSFET yog muab qhov ruaj khov rau cov khoom siv, yog li nws feem ntau siv hauv CPU, GPU thiab lub qhov (socket), thiab lwm yam.MOSFETsfeem ntau yog saum toj no thiab hauv qab daim ntawv ntawm ib pab pawg ntawm ob tshwm rau ntawm lub rooj tsavxwm.

MOSFET Pob

MOSFET nti hauv kev tsim khoom tiav, koj yuav tsum ntxiv lub plhaub rau MOSFET nti, uas yog, MOSFET pob. MOSFET nti plhaub muaj kev txhawb nqa, kev tiv thaiv, kev ua kom txias, tab sis kuj yog rau cov nti kom muab hluav taws xob sib txuas thiab kev sib cais, kom cov khoom siv MOSFET thiab lwm yam khoom siv los ua kom tiav Circuit Court.

Raws li kev teeb tsa hauv PCB txoj kev kom paub qhov txawv,MOSFETpob muaj ob pawg tseem ceeb: Los ntawm Qhov Nto thiab Nto Mount. ntxig yog MOSFET tus pin los ntawm PCB mounting qhov welded ntawm PCB. Surface Mount yog MOSFET tus pin thiab lub dab dej kub flange welded rau PCB nto pads.

Standard Package Specifications TO Pob

TO (Transistor Out-line) yog pob khoom thaum ntxov, xws li TO-92, TO-92L, TO-220, TO-252, thiab lwm yam. Nyob rau hauv xyoo tas los no, qhov saum npoo mount kev lag luam xav tau nce, thiab TO pob khoom tau nce mus rau saum npoo pob khoom.

TO-252 thiab TO263 yog cov pob khoom ntog. TO-252 tseem hu ua D-PAK thiab TO-263 tseem hu ua D2PAK.

D-PAK pob MOSFET muaj peb lub electrodes, rooj vag (G), ntws (D), qhov chaw (S). Ib qho ntawm cov dej ntws (D) tus pin yog txiav tsis siv lub nraub qaum ntawm lub dab dej kub rau qhov ntws (D), ncaj qha welded rau PCB, ntawm ib sab, rau qhov tso tawm ntawm cov hluav taws xob siab, ntawm ib sab, los ntawm cov PCB tshav kub dissipation. Yog li muaj peb lub PCB D-PAK pads, qhov ntws (D) ncoo loj dua.

Pob TO-252 tus pin daim duab

Chip pob nrov lossis dual hauv-kab pob, hu ua DIP (Dual ln-line Package).DIP pob thaum lub sijhawm ntawd muaj qhov tsim nyog PCB (luam tawm Circuit Board) perforated installation, nrog yooj yim dua TO-hom pob PCB thaiv thiab ua haujlwm. yog qhov yooj yim dua thiab yog li ntawm qee tus yam ntxwv ntawm cov qauv ntawm nws cov pob nyob rau hauv daim ntawv ntawm ntau cov ntaub ntawv, nrog rau ntau txheej ceramic dual hauv-kab DIP, ib txheej Ceramic Dual Hauv kab

DIP, txhuas ncej DIP thiab lwm yam. Feem ntau siv nyob rau hauv lub hwj chim transistors, voltage regulator nti pob.

ChipMOSFETPob

SOT pob

SOT (Small Out-Line Transistor) yog pob ntawv me me transistor. Cov pob no yog SMD me me fais fab transistor pob, me dua TO pob, feem ntau yog siv rau me me fais fab MOSFET.

SOP Pob

SOP (Small Out-Line Package) txhais tau hais tias "Cov Kab Qhia me me" hauv Suav, SOP yog ib qho ntawm cov pob khoom ntog, cov pins los ntawm ob sab ntawm lub pob nyob rau hauv cov duab ntawm tus gull tus tis (L-shaped), cov khoom siv. yog yas thiab ceramic. SOP tseem hu ua SOL thiab DFP. SOP pob cov qauv suav nrog SOP-8, SOP-16, SOP-20, SOP-28, thiab lwm yam. Tus lej tom qab SOP qhia txog tus lej pins.

SOP pob ntawm MOSFET feem ntau txais SOP-8 specification, kev lag luam nyhav kom tshem tawm "P", hu ua SO (Small Out-Line).

SMD MOSFET Pob

SO-8 pob yas, tsis muaj thermal puag phaj, tsis zoo cua sov dissipation, feem ntau yog siv rau MOSFET uas tsis muaj zog.

SO-8 yog thawj zaug tsim los ntawm PHILIP, thiab tom qab ntawd maj mam muab los ntawm TSOP (thin me me txheej txheem pob), VSOP (pob ntawv me me), SSOP (txo SOP), TSSOP (nyias txo SOP) thiab lwm yam kev qhia tshwj xeeb.

Ntawm cov pob khoom tshwj xeeb no, TSOP thiab TSSOP feem ntau yog siv rau MOSFET pob.

Chip MOSFET Pob

QFN (Quad Flat Non-leaded pob) yog ib qho ntawm cov pob khoom saum npoo av, Suav hu ua plaub-sab uas tsis yog-txheej txheem pob, yog lub ncoo loj me me, me me, yas raws li cov khoom sib khi ntawm cov txheej txheem mounting. ntim tshuab, tam sim no feem ntau hu ua LCC. Tam sim no nws yog hu ua LCC, thiab QFN yog lub npe teev tseg los ntawm Nyiv Hluav Taws Xob thiab Mechanical Industries Association. Lub pob yog configured nrog electrode hu rau txhua sab.

Lub pob tau teeb tsa nrog cov xov tooj hluav taws xob ntawm tag nrho plaub sab, thiab vim tias tsis muaj cov hlau lead, qhov chaw txuas yog me dua QFP thiab qhov siab qis dua ntawm QFP. Cov pob no tseem hu ua LCC, PCLC, P-LCC, thiab lwm yam.
