MOSFET palokha ili ndi maubwino ambiri, koma nthawi yomweyo MOSFET imakhala ndi mphamvu zochulukira kwakanthawi kochepa, makamaka pamawonekedwe ogwiritsira ntchito pafupipafupi, motero pakugwiritsa ntchito mphamvu.Zithunzi za MOSFET iyenera kupangidwa kuti ikhale yogwira ntchito yotetezera kuti ipititse patsogolo kukhazikika kwa chipangizocho.
Kunena mosapita m'mbali chitetezo overcurrent, ndi linanena bungwe la yochepa dera zolakwika kapena zimamuchulukira pa magetsi kapena katundu kukonza, pa siteji iyi ya magetsi overcurrent chitetezo pali njira zosiyanasiyana, monga nthawi zonse-panopa, nthawi zonse linanena bungwe. mtundu mphamvu, etc., koma chitukuko cha overcurrent dera chitetezo sangathe kulekana ndi MOSFET, ndi MOSFETs apamwamba akhoza kusintha udindo wa magetsi overcurrent chitetezo.
