NCEP055N30GU
30 V / 55 A NCE Power SGT MOSFET, 4.2 mOhm, DFN5x6 for dense DC-DC, load switches and battery protection.
The NCEP055N30GU is a 30 V / 55 A NCE Power N-channel MOSFET from the Shielded Gate Trench (SGT) family, in the compact surface-mount DFN5x6 package, with a typical on-resistance of 4.2 milliohm at a 10 V gate drive. The SGT structure reduces both on-resistance and gate charge, so the device delivers an excellent figure of merit for high-frequency switching and synchronous rectification, and the small DFN5x6 footprint suits a dense, high-frequency board where the thermal path runs through the PCB copper. The 30 V class and 55 A rating fit low-voltage DC-DC converters, load switches, battery protection and charger output stages, where efficiency and current density both matter. A power MOSFET turns on with a simple voltage drive, and the fast body diode allows the switch to freewheel cleanly in a bridge. Every device is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Designers should confirm the gate drive, the switching loop and the hot on-resistance for the thermal design. BeiLuo holds this class in stock and our FAE team supports gate drive, layout and thermal validation.
FAE Professional Review
The NCEP055N30GU is a compact 30 V SGT MOSFET in a DFN5x6, ideal for dense DC-DC and load-switch designs where board space is tight and switching frequency is high. The low gate charge keeps the drive simple, and the thermal path runs through the PCB copper. Confirm the copper area and thermal vias.

Frequently Asked Questions
What projects suit the NCEP055N30GU?
It fits low-voltage, medium-current converters such as DC-DC stages, load switches and battery protection circuits that run from a 24 V or lower bus. The small DFN5x6 package suits a dense, high-frequency board.
For higher current, step up to the NCEP018N60T.
How do I handle the thermal path in a DFN package?
A surface-mount DFN5x6 conducts heat through the PCB, so the copper area and thermal vias under the drain pad matter as much as the board thickness. Provide generous copper and connect it to a thermal plane, then confirm the case temperature under load.
Our FAE team can review your layout.
