MMN1000DB010B
100 V / 1250 A MacMic half-bridge MOSFET module with 0.57 mOhm Rds(on) for battery-source motor drives.
The MMN1000DB010B is a 100 V / 1250 A MacMic power MOSFET module in a half-bridge configuration, delivering exceptionally low RDS(on) around 0.57 mOhm and high current capability in a single package. The half-bridge arrangement suits inverter and synchronous rectification circuits for battery-source motor drives in roughly the 2-15 kW class, where a module avoids paralleling discretes and keeps current sharing predictable. Its low on-resistance holds conduction loss down at hundreds of amps, and the module's thermal coupling keeps the two switches at similar temperatures. High avalanche energy provides margin for inductive loads. Every module is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Because the current is high, confirm busbar inductance, gate drive strength and the RDS(on) hot value with our FAE team, and validate the thermal design against your duty cycle before layout sign-off. Every order includes import, origin and RoHS documents, and BeiLuo can confirm availability and lead time for the production volumes your drive program requires.
FAE Professional Review
The MMN1000DB010B is a half-bridge for serious current. At about 0.57 mOhm it keeps conduction loss tiny even at 1000 A, which is hard to achieve with discretes. Watch busbar inductance; at this current the commutation loop dominates.

Frequently Asked Questions
What applications suit a 1250 A half-bridge module?
It fits battery-source motor-drive inverters in the 2-15 kW class, high-current synchronous rectification and plating power. The half-bridge avoids paralleling discretes and keeps current sharing predictable.
Confirm your topology before selecting.
How do I control busbar and gate inductance?
At these currents the commutation loop dominates ringing and overshoot. Use laminated busbars, keep the loop tight, and drive the gates with a stiff, short loop.
Our FAE team can review your layout.
How do I plan thermal design at 1250 A?
Use the datasheet RthJC plus interface and heatsink resistance, and verify junction temperature at your duty cycle. Liquid cooling is typical at this current level.
Request a thermal review before committing the heatsink.
Is lead time longer for this part?
High-current modules can be scheduled rather than stocked, so confirm annual volume early. BeiLuo sources through MacMic's authorized channel and reserves supply against your plan.
