55N03LTA is TrenchMOS Logic Level FET.  N-channel logic level field-effect power transistor in a plastic package using TrenchMOS technology.

An N-channel logic level field-effect power transistor is a specific type of power transistor that uses an N-channel metal-oxide-semiconductor field-effect transistor (MOSFET) configuration.. These transistors are commonly used in electronic circuits for switching and amplifying purposes, where the ability to operate with low-voltage logic signals is important.
