U haynta MOSFET sida Beddel ahaan: Hagaha Dhaqangelinta Dhamaystiran ee Korontada Elektarooniga ah

Dulmar degdeg ah:Hagahan dhammaystiran waxa uu sahaminayaa sida si wax ku ool ah loogu isticmaalo MOSFET-yada sida beddelka codsiyada elektarooniga ah, iyada oo diiradda la saarayo hirgelinta wax ku oolka ah iyo xalalka adduunka dhabta ah.

Fahamka MOSFET Beddelka Aasaaska

Metal-Oxide-Semiconductor Field-Saamaynta Transistor-ka (MOSFETs) waxay wax ka beddeleen qalabka elektaroonigga ah ee casriga ah iyagoo siinaya xal beddel ah oo hufan oo la isku halayn karo. Adiga oo hormuud u ah alaab-qeybiyaha MOSFET-yada tayada sare leh, waxaanu kugu hagi doonaa wax kasta oo aad u baahan tahay inaad ka ogaato isticmaalka qaybahan kala duwan sida shixnad ahaan.

Mabaadi'da Hawlgelinta aasaasiga ah

MOSFET-yadu waxay u shaqeeyaan sidii furayaasha korantada lagu xakameeyo, iyagoo siinaya faa'iidooyin dhowr ah marka loo eego furayaasha farsamada dhaqameed iyo aaladaha kale ee semiconductor:

Xawaaraha beddelka degdega ah (kala duwanaansho second)
Iska caabin hoose oo gobolka ah (RDS(daar))
Isticmaalka tamarta ugu yar ee gobolada taagan
Ma jiro jeex iyo jeex farsamo
