Inowanzo shandiswa SMD MOSFET package pinout sequence details

Ndeipi basa reMOSFETs?

MaMOSFET anoita basa mukugadzirisa voltage yemagetsi ese emagetsi system. Parizvino, hapana maMOSFET akawanda anoshandiswa pabhodhi, kazhinji anenge anenge 10. Chikonzero chikuru ndechokuti vazhinji veMOSFETs vanobatanidzwa muI IC chip. Sezvo basa guru reMOSFET nderekupa mhepo yakagadzikana yemidziyo, saka inowanzo shandiswa muCPU, GPU uye socket, nezvimwe.MOSFETskazhinji pamusoro uye pazasi chimiro cheboka revaviri vanoonekwa pabhodhi.

MOSFET Package

MOSFET chip mukugadzirwa kwapera, unofanirwa kuwedzera ganda kune MOSFET chip, kureva, MOSFET package. MOSFET chip shell ine tsigiro, dziviriro, kutonhora mhedzisiro, asiwo kune chip kuti ipe magetsi kubatana nekuzviparadzanisa nevamwe, kuitira kuti MOSFET mudziyo uye zvimwe zvikamu zvigadzire dunhu rakazara.

Zvinoenderana nekuisirwa muPCB nzira yekusiyanisa,MOSFETpackage ine maviri makuru mapoka: Kuburikidza neHole uye Surface Mount. inoiswa pini yeMOSFET kuburikidza nePCB inokwira maburi akaiswa paPCB. Surface Mount ndiyo MOSFET pini uye kupisa sink flange yakasungirirwa kune PCB pamusoro pedhi.

Standard Package Zvinotsanangurwa KUTI Package

KUTI (Transistor Out-line) ndiyo yekutanga pasuru yakatarwa, senge TO-92, TO-92L, TO-220, TO-252, nezvimwewo iplug-in package dhizaini. Mumakore achangopfuura, kudiwa kwemusika wepamusoro kwakawedzera, uye TO mapakeji akafambira mberi kusvika pamusoro pemapakeji.

TO-252 uye TO263 ari pamusoro pegomo mapakeji. Iyo TO-252 inozivikanwa zvakare seD-PAK uye TO-263 inozivikanwa zvakare seD2PAK.

D-PAK package MOSFET ine matatu maelectrodes, gedhi (G), drain (D), sosi (S). Imwe yepini (D) pini inochekwa pasina kushandisa kuseri kwekugezera kwemvura yekugezera (D), yakanangana nePCB, kune rumwe rutivi, yekubuda kweiyo yakakwira ikozvino, kune rumwe rutivi, kuburikidza ne PCB kupisa kupisa. Saka kune matatu PCB D-PAK pads, iyo yekudhonza (D) padhi yakakura.

Package TO-252 pini dhayagiramu

Chip package yakakurumbira kana mbiri-mutsetse pasuru, inonzi DIP (Dual ln-line Package) .DIP package panguva iyoyo ine yakakodzera PCB (yakadhindwa redunhu bhodhi) perforated kugadzika, ine nyore kupfuura TO-mhando pasuru PCB wiring uye kushanda. iri nyore uye zvichingodaro mamwe emhando yechimiro chepakeji yayo nenzira yehuwandu hwemafomu, kusanganisira akawanda-layer ceramic dual in-line DIP, single-layer Ceramic Dual In-Line.

DIP, lead frame DIP uye zvichingodaro. Inowanzo shandiswa mumagetsi transistors, voltage regulator chip package.

SOT Package

SOT (Small Out-Line Transistor) idiki reratidziro transistor package. Iyi pasuru iSMD diki simba transistor package, idiki pane TO package, inowanzo shandiswa kune diki simba MOSFET.

SOP Package

SOP (Small Out-Line Package) zvinoreva "Small Outline Package" muchiChinese, SOP imwe yemapakeji epamusoro, mapini kubva kumativi maviri epakeji muchimiro chebapiro regull (L-shaped), zvinhu. ndiyo plastiki uye ceramic. SOP inonzi zvakare SOL uye DFP. SOP package miyero inosanganisira SOP-8, SOP-16, SOP-20, SOP-28, etc. Nhamba iri mushure meSOP inoratidza nhamba yepini.

Iyo SOP pasuru yeMOSFET inowanzo tora SOP-8 yakatarwa, iyo indasitiri inowanzosiya iyo "P", inonzi SO (Small Out-Line).

SMD MOSFET Package

SO-8 purasitiki pasuru, hapana chinopisa chigadziko chendiro, isina kupisa kupisa, chinowanzo shandiswa kune yakaderera-simba MOSFET.

SO-8 yakatanga kugadzirwa nePHILIP, uye zvishoma nezvishoma yakabva kuTSOP (yakaonda pepa rehurukuro), VSOP (duku duku rehurukuro pasuru), SSOP (yakaderedzwa SOP), TSSOP (yakaonda yakaderedzwa SOP) uye mamwe maitiro akajairwa.

Pakati peaya akatorwa epakeji zvirevo, TSOP neTSSOP zvinowanzo shandiswa kuMOSFET mapakeji.

Chip MOSFET Packages

QFN (Quad Flat Non-lead pasuru) ndeimwe yemapakeji epamusoro, maChinese anonzi mana-side non-lead flat package, idiki padhi, idiki, purasitiki sechinhu chekuvharisa chinobuda pamusoro pegomo chip. kurongedza tekinoroji, ikozvino inonyanya kuzivikanwa seLCC. Yave kunzi LCC, uye QFN izita rakataurwa neJapan Electrical and Mechanical Industries Association. Iyo package inogadziriswa ne electrode contacts kumativi ese.

Iyo pasuru inogadziriswa nemagetsi emagetsi pamativi ese mana, uye sezvo pasina anotungamira, nzvimbo yekumisikidza idiki pane QFP uye kureba kwakadzikira pane kuya kweQFP. Iyi pasuru inozivikanwawo seLCC, PCLC, P-LCC, nezvimwe.
