Bikunze gukoreshwa SMD MOSFET yamapaki pinout ikurikirana

Ni uruhe ruhare rwa MOSFETS?

MOSFETs igira uruhare mukugenzura voltage ya sisitemu yose itanga amashanyarazi. Kugeza ubu, nta MOSFETS nyinshi zikoreshwa ku kibaho, ubusanzwe zigera ku 10. Impamvu nyamukuru ni uko MOSFETs nyinshi zinjizwa muri chip ya IC. Kubera ko uruhare runini rwa MOSFET ari ugutanga voltage ihamye kubikoresho, bityo rero ikoreshwa muri CPU, GPU na sock, nibindi.MOSFETSmuri rusange hejuru no munsi yuburyo bwitsinda ryibiri rigaragara kurubaho.

Amapaki menshi

Chip ya MOSFET mubikorwa byarangiye, ugomba kongeramo igikonoshwa kuri chip ya MOSFET, ni ukuvuga paketi ya MOSFET. MOSFET chip shell ifite inkunga, kurinda, gukonjesha, ariko kandi kugirango chip itange umurongo wamashanyarazi no kwigunga, kuburyo igikoresho cya MOSFET nibindi bice bigize uruziga rwuzuye.

Ukurikije kwishyiriraho muburyo bwa PCB gutandukanya,BYINSHIpaki ifite ibyiciro bibiri byingenzi: Binyuze kuri Hole na Surface Umusozi. winjijwemo ni pin ya MOSFET unyuze muri PCB yimyobo isudira kuri PCB. Ubuso bwa Surface ni pin ya MOSFET hamwe nubushyuhe bwa sink flange yasuditswe kuri padi ya PCB.

Ibipimo bisanzwe bipfunyika kubipaki

TO (Transistor Out-line) nigitekerezo cyambere cyo gutondekanya, nka TO-92, TO-92L, TO-220, TO-252, nibindi ni plug-in igishushanyo mbonera. Mumyaka yashize, isoko ryisoko ryisoko ryiyongereye, kandi TO pack yateye imbere hejuru yububiko.

TO-252 na TO263 nubuso bwububiko. TO-252 izwi kandi nka D-PAK naho TO-263 izwi kandi nka D2PAK.

Porogaramu D-PAK MOSFET ifite electrode eshatu, irembo (G), imiyoboro (D), isoko (S). Imwe mumazi ya Dine (D) yaciwe adakoresheje inyuma yubushyuhe bwo gushyushya amazi (D), asudira neza kuri PCB, kuruhande rumwe, kugirango asohore amashanyarazi menshi, kuruhande rumwe, anyuze kuri Gukwirakwiza ubushyuhe bwa PCB. Hano hari udupapuro dutatu twa PCB D-PAK, imiyoboro ya drain (D) nini.

Gupakira TO-252 igishushanyo

Chip pack ikunzwe cyangwa ibiri mumurongo, byitwa DIP (Dual ln-line Package) .DIP yamashanyarazi muricyo gihe ifite PCB ikwiye (icapiro ryumuzingo wacapwe) yashizwemo, kandi byoroshye kuruta TO-Ubwoko bwa PC PC wiring no gukora ni byiza cyane kandi rero kuri bimwe mubiranga imiterere yububiko bwayo muburyo bwimibare myinshi, harimo ibice byinshi bya ceramic byombi kumurongo DIP, umurongo umwe Ceramic Dual In-Line

DIP, kuyobora ikadiri DIP nibindi. Bikunze gukoreshwa muri power transistors, voltage igenzura chip pack.

SOT

SOT (Gitoya-Imirongo Transistor) ni pake ya tristoriste. Iyi paki ni SMD ntoya ya transistor yamashanyarazi, ntoya kurenza TO pack, mubisanzwe ikoreshwa kububasha buto MOSFET.

SOP

SOP. ni plastiki na ceramic. SOP nayo yitwa SOL na DFP. Ibipimo bya SOP birimo SOP-8, SOP-16, SOP-20, SOP-28, nibindi. Umubare nyuma ya SOP werekana umubare wibipapuro.

Porogaramu ya SOP ya MOSFET ahanini ifata ibisobanuro bya SOP-8, inganda zikunda gusiba "P", bita SO (Ntoya-Umurongo).

Ububiko bwa SMD MOSFET

Porogaramu ya plastike ya SO-8, nta plaque yubushyuhe ihari, kugabanuka kwubushyuhe, mubisanzwe bikoreshwa mumashanyarazi make MOSFET.

SO-8 yabanje gutunganywa na PHILIP, hanyuma buhoro buhoro ikomoka kuri TSOP (pake ntoya yoroheje), VSOP (pake ntoya cyane), SSOP (yagabanije SOP), TSSOP (yagabanutse SOP) nibindi bisobanuro bisanzwe.

Muri ibyo bisobanuro byatanzwe, TSOP na TSSOP bikoreshwa mubisanzwe MOSFET.

Chip MOSFET

QFN. tekinoroji yo gupakira, ubu izwi cyane nka LCC. Ubu yitwa LCC, naho QFN ni izina ryashyizweho n’ishyirahamwe ry’inganda z’amashanyarazi n’Ubuyapani. Ipaki igizwe na electrode ihuza impande zose.

Ipaki igizwe na electrode ihuza kumpande zose uko ari enye, kandi kubera ko nta ziyobora, agace kegeranye ni nto kurenza QFP kandi uburebure buri munsi ya QFP. Iyi paki izwi kandi nka LCC, PCLC, P-LCC, nibindi.
