The RUE002N02TL is a surface mount signal MOSFET made by ROHM. It is an N-channel MOSFET, meaning it is a type of transistor that can be used to control the flow of electrical current, and has a maximum drain-source voltage of 20 volts and a maximum drain current of 0.2 amps. Its primary function is to control switch signals in electronic circuits, and can be used in a wide range of applications including logic level translation, power supplies, amplifiers, motor controls, battery management, switching regulators, and other types of circuits. Its small footprint allows for easy installation in tight spaces.
