Description
55N03LTA is 25V, Logic Level FET. N-channel logic level field-effect power transistor in a plastic package using TrenchMOS technology.
An N-channel MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a type of field effect transistor (FET) that uses an N-type semiconductor material as the conducting channel to control the flow of current.
When a positive voltage is applied to the gate terminal, it attracts electrons to the channel, creating an inversion layer and allowing current to flow between the source and drain terminals.
