The MDP5N50F, MDF5N50F use advanced Magnachip’s MOSFET Technology, which provides low on-state resistance, high switching performance and excellent quality. MDP5N50F/MDF5N50F are suitable device for SMPS, HID and general purpose applications.

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.

N-channel MOSFETs are widely used in a variety of electronic applications due to their high input impedance, fast switching speeds, and low power consumption. They are commonly used as switches, amplifiers, and voltage regulators.
