Fuji Electric 7MBR100XRE120-50 1200V 100A IGBT Module

Fuji Electric 7MBR100XRE120-50 — High-Density 1200 V / 100 A IGBT PIM

The Fuji Electric 7MBR100XRE120-50 is a compact, high-performance IGBT power module from Fuji’s X-series PIM family, engineered for demanding industrial power-electronics uses such as three-phase inverters, NC servo drives and uninterruptible power supplies. It delivers a 1200 V collector–emitter rating with a continuous inverter collector current of 100 A (Tc = 100 °C) and low VCE(sat), helping systems achieve high power density while keeping conduction losses low. The module integrates converter and dynamic-brake circuitry in a PCB-mountable PIM package, simplifying design and saving board space for dense motor-drive and UPS assemblies.

Built for long service life under heavy switching, the 7MBR100XRE120-50 supports high junction temperatures (inverter/brake Tvj up to 175 °C) and offers substantial collector power dissipation (Pc ≈ 685 W for the inverter device), enabling robust thermal tolerance in continuous and transient loads. It also provides strong surge capability (IFSM ≈ 945 A at Tvj = 25 °C) and converter average-output capability suitable for three-phase full-wave converter use, so designers can confidently handle short-term overloads and dynamic braking without excessive derating. These characteristics make the module well suited to industrial and commercial applications where efficiency, durability and predictable thermal performance matter.

From a system-integration standpoint the PIM’s compact outline and recommended mounting details simplify assembly into power stacks and drive PCBs. The module’s gate-emitter rating (±20 V), recommended M5 screw torque range and PCB-mount form factor reduce mechanical and layout complexity during installation, helping shorten development time and lower BOM overhead for motor control and UPS vendors.
