I-MOSFET ngokwayo ineengenelo ezininzi, kodwa kwangaxeshanye i-MOSFET inobuntununtunu bexeshana elifutshane lomthwalo wokugcwala, ngakumbi kwiimeko zesicelo esine-frequency ephezulu, ngoko ke kusetyenziso lwamandla.Ii-MOSFETs kufuneka iphuhliswe kwisekethe yayo yokukhusela esebenzayo ukuqinisa uzinzo lwesixhobo.
Ukuyibeka ngokungqongqo ukhuseleko lwe-overcurrent, lukwimveliso yeempazamo zesekethe ezimfutshane okanye umthwalo ogqithisiweyo kunikezelo lwamandla okanye ukugcinwa komthwalo, kweli nqanaba lonikezelo lwamandla okhuseleko lwe-overcurrent kukho iindlela ezahlukeneyo, ezinje ngokuqhubekayo-yangoku, ukuphuma rhoqo. uhlobo lwamandla, njl.njl., kodwa uphuhliso lwesekethe yokhuseleko lwe-overcurrent alunakwahlulwa kwi-MOSFET, i-MOSFETs ekumgangatho ophezulu inokuphucula indima yonikezelo lwamandla ukhuseleko olungaphaya.
