Menene aikin MOSFETs?

MOSFETs suna taka rawa wajen daidaita ƙarfin wutar lantarki duka tsarin samar da wutar lantarki. A halin yanzu, babu MOSFET da yawa da ake amfani da su a kan allo, yawanci kusan 10. Babban dalilin shine yawancin MOSFETs an haɗa su cikin guntu IC. Tunda babban aikin MOSFET shine samar da ingantaccen ƙarfin lantarki don na'urorin haɗi, don haka ana amfani dashi gabaɗaya a cikin CPU, GPU da soket, da sauransu.MOSFETsgabaɗaya suna sama da ƙasa nau'in rukuni na biyu suna bayyana akan allo.

TO (Transistor Out-line) shine ƙayyadaddun fakiti na farko, kamar TO-92, TO-92L, TO-220, TO-252, da sauransu. A cikin 'yan shekarun nan, buƙatun kasuwa na kasuwa ya karu, kuma TO fakitin sun ci gaba zuwa fakitin hawa saman.

TO-252 da TO263 sune fakitin hawa saman. TO-252 kuma ana kiranta D-PAK kuma TO-263 kuma ana kiranta D2PAK.

Kunshin D-PAK MOSFET yana da lantarki guda uku, kofa (G), lambatu (D), tushen (S). Ɗaya daga cikin magudanar ruwa (D) yana yanke ba tare da amfani da baya na magudanar zafi don magudanar (D), kai tsaye welded zuwa PCB, a gefe guda, don fitar da babban halin yanzu, a daya hannun, ta hanyar PCB zafi watsar. Don haka akwai pad ɗin PCB D-PAK guda uku, kushin (D) ya fi girma.

Kunshin SOT

SOT (Small Out-line Transistor) ƙaramin fakitin transistor ne. Wannan fakitin ƙaramin fakitin transistor ne na SMD, ƙarami fiye da kunshin TO, gabaɗaya ana amfani da shi don ƙaramin iko MOSFET.

Kunshin SOP

SOP (Ƙananan Kunshin Layi) yana nufin "Ƙananan Kunshin Shafi" a cikin Sinanci, SOP ɗaya ne daga cikin fakitin dutsen saman, fil ɗin daga bangarorin biyu na kunshin a cikin siffar reshe na gull (L-dimbin yawa), kayan filastik ne da yumbu. Ana kuma kiran SOP SOL da DFP. Ka'idodin kunshin SOP sun haɗa da SOP-8, SOP-16, SOP-20, SOP-28, da sauransu. Lamba bayan SOP yana nuna adadin fil.

Kunshin SOP na MOSFET galibi yana ɗaukar ƙayyadaddun SOP-8, masana'antar tana son barin "P", wanda ake kira SO (Ƙananan Layi).

Kunshin MOSFET SMD

Kunshin filastik SO-8, babu farantin tushe na thermal, ƙarancin zafi mai zafi, galibi ana amfani dashi don MOSFET mai ƙarancin ƙarfi.

PHILIP ne ya fara samar da SO-8, sannan kuma a hankali ya samo asali daga TSOP (kananan ƙaramin fakitin fakiti), VSOP (ƙananan fakitin fakiti), SSOP (raguwar SOP), TSSOP (SOP na bakin ciki) da sauran ƙayyadaddun ƙayyadaddun bayanai.

Daga cikin waɗannan ƙayyadaddun fakitin da aka samo, ana amfani da TSOP da TSSOP don fakitin MOSFET.

Kunshin MOSFET Chip

QFN (Quad Flat Non-leaded kunshin) yana daya daga cikin fakitin dutsen saman, Sinawa da ake kira fakitin lebur mai gefe hudu, girman kushin ne karami, karami, filastik azaman abin rufewa na guntun dutsen da ke fitowa. fasahar marufi, wanda yanzu aka fi sani da LCC. Yanzu ana kiransa LCC, kuma QFN shine sunan da Ƙungiyar Masana'antar Lantarki da Makanikai ta Japan ta ayyana. An saita kunshin tare da lambobin lantarki a kowane bangare.

An saita kunshin tare da lambobin lantarki a duk bangarorin hudu, kuma tunda babu jagora, wurin hawan ya fi QFP karami kuma tsayin ya yi kasa da na QFP. Ana kuma san wannan fakitin da LCC, PCLC, P-LCC, da sauransu.
