The RUM002N05T2L is a surface-mounted MOSFET (metal oxide semiconductor field effect transistor) manufactured by ROHM. It is a n-channel type MOSFET and has three pins that allow it to dissipate heat more effectively; two power pins (source and drain) and a control gate pin. This MOSFET has a maximum voltage rating of 50V and a maximum current rating of 0.2A. The device is typically used to control and manage power to other components in an electronic circuit, such as a switching power supply or a DC-DC converter.
