MM50G3T120BM
1200 V / 50 A MacMic G3T discrete IGBT in TO-247 Plus for motor drives and power conversion below 15 kHz.
The MM50G3T120BM is a 1200 V / 50 A MacMic discrete IGBT in the TO-247 Plus package, from the G3T series optimized for typical power applications up to 15 kHz. Its typical saturation voltage of 1.8 V, 535 W power dissipation and 0.28 K/W junction-to-case thermal resistance make it a strong fit for motor drives, power conversion and inverter stages where conduction loss dominates. TO-247 Plus extends the current capability of a single device compared with a standard TO-247, so high-power designs avoid paralleling and its current-sharing challenges. The Trench Field-Stop chip provides a good balance of conduction and switching loss, and the rugged device tolerates short-circuit events common in motor-drive equipment. Every device is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Confirm gate drive, dead time and the 0.28 K/W thermal path with our FAE team before finalizing your layout. Every order includes import, origin and RoHS documents, and BeiLuo can confirm availability and lead time for the ratings your production plan requires.
FAE Professional Review
The MM50G3T120BM pairs the 1200 V class with the wider TO-247 Plus package, so it carries 50 A without paralleling. It is a good choice for motor-drive and conversion stages below 15 kHz where conduction loss sets the thermal budget.

Frequently Asked Questions
Why choose TO-247 Plus for a 1200 V design?
TO-247 Plus extends the current range of a single device, so a 50 A design avoids paralleling two standard parts and the current-sharing risk that brings. It keeps the layout compact and reliable.
Consider it whenever a standard TO-247 rating falls short.
G3T is for below 15 kHz: is that my case?
G3T targets motor drive, power conversion and other circuits below 15 kHz where conduction loss dominates. If your design switches above 15 kHz, choose the G3U series instead.
Match the series to your switching frequency first.
How do I manage heat at 50 A?
Start from the 0.28 K/W RthJC, add interface and heatsink resistance, and verify junction temperature at continuous current. The TO-247 Plus footprint spreads heat over a larger area.
Request a thermal review of your heatsink.
Is lead time longer for this part?
Availability is confirmed per request; some ratings are held in stock while others are scheduled. BeiLuo sources through MacMic's authorized channel.
