MMN400A010U1
100 V / 400 A MacMic MOSFET module, low Rds(on), single-switch, for high-power synchronous rectification.
The MMN400A010U1 is a 100 V / 400 A MacMic power MOSFET module in a single-switch configuration, offering low RDS(on) and high current carrying capability from one tested package. Instead of paralleling many discrete MOSFETs, a module guarantees current sharing and thermal coupling, which raises production yield and reliability. With a typical on-resistance around 1.4 mOhm and a junction-to-case thermal resistance of 0.14 K/W, it is an effective high-power synchronous rectifier for plating power supplies and similar low-voltage, high-current equipment. The single-switch configuration also serves as a solid-state replacement for a mechanical contactor, switching large currents without wear. High avalanche energy adds margin for inductive loads. Every module is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Confirm gate drive, thermal design and the RDS(on) hot value with our FAE team before finalizing your layout. The module ships with import, origin and RoHS documentation, and BeiLuo supports sample evaluation so you can confirm RDS(on) and thermal behavior at your load.
FAE Professional Review
The MMN400A010U1 is the module we recommend for low-voltage, high-current synchronous rectification. At about 1.4 mOhm, conduction loss stays low at 200-300 A continuous, and the module removes the current-sharing headache of paralleled discretes.

Frequently Asked Questions
Why use a MOSFET module instead of discretes?
A module guarantees current sharing and thermal coupling in one tested part, raising yield and reliability. It removes the layout and matching problems of paralleling many discretes.
It is the practical choice above a few hundred amps.
How do I size the synchronous rectifier?
Pick the lowest RDS(on) at your current and gate drive, then verify thermal resistance and avalanche margin. Check the RDS(on) hot value, not just the 25 C figure.
Our FAE team can compare candidates at your load.
What gate drive and layout does it need?
Use a stiff driver with a short gate loop and tune the gate resistance to your EMI target. Keep the power loop small to limit ringing at these currents.
