MMG100J120UZ
1200 V / 100 A MacMic HN-series IGBT module, half-bridge GJ package, 1.8 V Vce(sat) for high-frequency drives.
The MMG100J120UZ is a 1200 V / 100 A MacMic IGBT module from the HN high-speed series, built on Trench Field-Stop technology for low switching and conduction loss. With a typical saturation voltage of 1.8 V, 690 W total power dissipation and a junction-to-case thermal resistance of 0.18 K/W, it suits hard-switched inverters running up to tens of kilohertz, including motor drives, welding inverters and induction heating. The GJ package with a flat substrate provides a low thermal resistance and a rugged, industry-standard footprint for both non-isolated and isolated designs. A co-packaged freewheeling diode supports half-bridge and three-phase bridge circuits without extra components. Every module is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Engineers choosing this part should budget gate drive and dead time for the switching energy and confirm the heatsink against the 0.18 K/W thermal path. BeiLuo holds this module in stock and can supply samples with a full import, certificate of origin and RoHS documentation package for your evaluation.
FAE Professional Review
The MMG100J120UZ is our go-to module for 1200 V stages in the 30-60 kW class. The 1.8 V saturation voltage keeps conduction loss low, and the 0.18 K/W thermal path lets a modest heatsink handle the load. Watch the gate loop when you push toward 50 kHz.

Frequently Asked Questions
What projects suit the MMG100J120UZ?
It fits 1200 V hard-switched inverters in the 30-60 kW class such as motor drives, welding inverters and induction heating. The 100 A rating and 0.18 K/W thermal path keep a modest heatsink viable.
For higher current in the same class, step up to the MMG400KR120U.
How high can I switch this module?
The HN series supports hard switching up to about 50 kHz with VCE(sat) around 2.0 V. Above 20 kHz, gate-loop layout and gate resistance dominate EMI and overshoot.
Our FAE team can review your switching target.
What thermal points matter for installation?
Use a thin, uniform thermal interface and verify junction temperature at worst-case current using the 0.18 K/W RthJC plus your interface and heatsink resistance. The flat substrate keeps contact consistent.
Request a thermal review for your heatsink.
Is the module genuine and documented?
BeiLuo supplies factory-traceable MMG100J120UZ modules with import declaration, certificate of origin and RoHS files on every order. Stock is normally available.
