SGM300HF12A3TFD
1200 V / 300 A Silan SGM industrial IGBT module in A3 2-pack, 2.2 V VCE(sat), for motor drives, UPS and solar.
The SGM300HF12A3TFD is a 1200 V / 300 A Silan industrial IGBT module in the A3 2-pack package, with a typical saturation voltage of 2.2 V. A 2-pack module contains two IGBT switches with their anti-parallel freewheeling diodes, forming one half-bridge leg, so three modules build a complete three-phase inverter. The A3 package provides a low-inductance internal structure and a large insulating substrate for effective heat spreading, and the 1200 V class gives the margin a 380 to 480 V AC drive needs. The 300 A rating covers a wide range of industrial inverters, motor drives, UPS and solar power stages, and the module reduces the parts count, wiring and assembly time of the power stage compared with a discrete design. Silan manufactures the IGBT and diode chips in-house, which keeps lot-to-lot consistency tight. Every module is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Designers should confirm busbar inductance, gate-drive values and the thermal path before layout sign-off. BeiLuo holds this module in regional stock and can supply samples with the full documentation package, and our FAE team supports gate-drive, layout and thermal design.
FAE Professional Review
The SGM300HF12A3TFD is the 1200 V 2-pack we reach for in the low-hundreds-of-amps class. The A3 low-inductance package makes turn-off overshoot predictable, and 300 A from one leg covers most industrial drives. Control the commutation loop and the gate path and it is a forgiving module.

Frequently Asked Questions
What projects suit the SGM300HF12A3TFD?
It fits 1200 V hard-switched inverters in the tens-of-kilowatts class such as motor drives, UPS stages and solar converters. Three modules build a three-phase bridge, so it is a flexible building block.
For higher current or a lower saturation voltage, consider the SGM450HF12B4TFD half-bridge.
Is a 2-pack module hard to apply?
A 2-pack is the building block of a three-phase inverter: use three for a full bridge, or one for a half-bridge leg or a chopper. It keeps each switch thermally independent and gives you flexibility to add a brake or a separate leg.
Our selection guide walks through the layout.
How do I plan the thermal design?
Begin from RthJC in the datasheet, add interface and heatsink resistance, and verify junction temperature at worst-case current. The A3 flat substrate keeps the thermal path consistent.
