MMN13J120U
1200 V / 107 A MacMic SiC MOSFET module in rugged SOT-227, 13.4 mOhm Rds(on) for industrial and PV use.
The MMN13J120U is a 1200 V / 107 A MacMic silicon carbide MOSFET module in the rugged SOT-227 package, with a typical RDS(on) of about 13.4 mOhm and a 175 C junction rating. The SOT-227 footprint installs with a standard screw-mount heatsink and is well proven in industrial equipment, making it a practical single-switch SiC option where mechanical robustness matters alongside high switching speed. SiC reduces switching loss and supports higher frequencies than silicon, which improves efficiency and shrinks magnetics in industrial drives, photovoltaic inverters and charging equipment. Because there is no tail current, transitions are clean, and gate drive is more straightforward than silicon IGBT turn-off trade-offs. Every module is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Confirm gate resistance, loop inductance and the RDS(on) hot value with our FAE team before layout, and validate the thermal design for continuous operation at 175 C. Each module ships with import, origin and RoHS documents, and BeiLuo can support your qualification testing and volume planning with genuine, traceable parts.
FAE Professional Review
The MMN13J120U trades a little RDS(on) for the rugged, familiar SOT-227 mounting. It is the SiC module we suggest when a customer wants proven mechanical robustness with the efficiency gains of silicon carbide in an industrial drive or inverter.

Frequently Asked Questions
Why choose the SOT-227 SiC module?
SOT-227 is a proven, screw-mount package that installs easily on standard heatsinks. This module pairs that robustness with SiC efficiency, making it a good fit for industrial drives and inverters.
For the lowest RDS(on), consider the NCB SiC module.
How does SiC change my switching design?
SiC switches fast with no tail current, so you can raise frequency and shrink magnetics, but gate-loop inductance and gate resistance then dominate ringing. Keep loops short.
Our SiC review covers gate-drive practice.
How do I mount and cool a SOT-227 module?
Apply the recommended torque and a thin thermal interface, then verify case temperature at full load. The package spreads heat across its metal base.
Request a thermal review for your heatsink.
Is lead time longer for SiC parts?
SiC modules can be scheduled rather than stocked, so confirm volume early. BeiLuo sources through MacMic's authorized channel and reserves supply against your plan.
