The MGSF1N02LT1G is a metal oxide semiconductor field-effect transistor (MOSFET), manufactured by ON Semiconductor. It is a surface-mount device in a small-outline package (SOT23) and is designed for low-power applications. It is an N-channel MOSFET with a drain-source voltage rating of 20 volts (VDS) and a drain current rating of 75 milli-amperes (ID). The on-state resistance (RDS(on)) is very low, at 90 milli-ohms (mO). It is very suitable for use as a switch in electronic applications such as motor control and other power management systems.
