5N52U is N-channel 525 V, 1.25 Ω typ., 4.4 A, UltraFAST Power MOSFET. This device is N-channel Power MOSFET developed using UltraFASTmesh technology, which combines the advantages of reduced on resistance, Zener gate protection and very high dv/dt capability with an enhanced fast body-drain recovery diode.

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.


• Outstanding dv/dt capability

• Gate charge minimized

• Very low intrinsic capacitances

• Very low RDS(on) • Extremely low trr
