WebHowever, the minority current electrons (as you will see later) play the most important part in the operation of the NPN transistor. These minority carriers actually conduct the current for the reverse-biased junction when electrons from the P material enter the N material, and the holes from the N material enter the P material. WebA lyukak a fő töltéshordozók az NPN tranzisztorban? Magyarázat: Az npn tranzisztorban a bal oldali n-régió (kibocsátó) erősen adalékolt. Tehát az emitternek nagy számú szabad elektronja van. Tudjuk, hogy a p-típusú félvezetőben a lyukak a többségi töltéshordozók, és a szabad elektronok a kisebbségi töltéshordozók.
