MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistor) galibi ana ɗaukar su azaman na'urori masu cikakken sarrafawa. Wannan saboda yanayin aiki (a kunne ko kashe) na MOSFET ana sarrafa shi gaba ɗaya ta hanyar wutar lantarki ta ƙofar (Vgs) kuma baya dogara da tushe na yanzu kamar yadda yake a cikin yanayin transistor bipolar (BJT).
A cikin MOSFET, ƙarfin wutar lantarki na ƙofar Vgs yana ƙayyade ko an samar da tashar gudanarwa tsakanin tushen da magudanar ruwa, da kuma faɗin tashar sarrafawa. Lokacin da Vgs ya wuce ƙarfin ƙarfin kofa na Vt, an kafa tashar gudanarwa kuma MOSFET ta shiga cikin ƙasa; lokacin da Vgs ya faɗi ƙasa da Vt, tashar mai gudanarwa ta ɓace kuma MOSFET tana cikin yanayin yankewa. Wannan iko yana da cikakken sarrafawa saboda ƙarfin wutar lantarki na ƙofar yana iya kansa da kansa kuma daidai yake sarrafa yanayin aiki na MOSFET ba tare da dogaro da wasu sigogin halin yanzu ko ƙarfin lantarki ba.
Sabanin haka, yanayin aiki na na'urori masu sarrafa rabin-tsayi (misali, thyristors) ba kawai yana shafar wutar lantarki ko na yanzu ba, har ma da wasu dalilai (misali, ƙarfin lantarki na anode, na yanzu, da sauransu). Sakamakon haka, na'urori masu cikakken sarrafawa (misali, MOSFETs) yawanci suna ba da kyakkyawan aiki dangane da daidaiton sarrafawa da sassauci.
A taƙaice, MOSFETs na'urori ne masu cikakken sarrafawa waɗanda yanayin aiki gaba ɗaya ke sarrafa su ta hanyar wutar lantarki ta ƙofar, kuma suna da fa'idodin daidaitattun daidaito, babban sassauci da ƙarancin wutar lantarki.
