The Fuji 1MBH10D-120 is a single-configuration Insulated Gate Bipolar Transistor (IGBT) module rated for 10A continuous collector current and 1200V blocking voltage. Built to Fuji Electric's established IGBT module standards, this device integrates a high-speed switching IGBT with a freewheeling diode in a compact, isolated baseplate package. The 1200V voltage class makes it suitable for 480V and 600V AC bus topologies, while the 10A current rating targets low-to-medium power stages where precision gate control and low conduction losses are required in a modular form factor.

The 1MBH10D-120 is well suited for industrial variable frequency drives (VFDs), uninterruptible power supplies (UPS), switched-mode power supplies (SMPS), induction heating equipment, and auxiliary inverter stages in renewable energy systems. Its single-switch configuration also makes it a practical choice for engineers designing custom half-bridge or chopper circuits, or replacing individual switching legs in multi-module assemblies. Wherever 1200V-class IGBT switching is needed in a controlled, thermally manageable package, this Fuji module delivers consistent performance in demanding industrial environments.

Key Features of the 1MBH10D-120:

• 1200V VCES rating supports 480V and 600V AC line applications with robust voltage margin
• 10A continuous collector current (IC) in a single-switch topology for flexible circuit integration
• Integrated freewheeling diode eliminates the need for an external anti-parallel rectifier in most designs
• Isolated copper baseplate construction enables direct heatsink mounting with standard thermal interface materials
• Low gate charge and optimized turn-off characteristics reduce switching losses at standard industrial frequencies
• Compatible with standard Fuji 1MBH-series footprints, simplifying drop-in replacement in existing assemblies

With a current factory lead time of 99 weeks from Fuji Electric, the 1MBH10D-120 presents a serious procurement risk for maintenance teams and production planners alike. A single unplanned failure or an upcoming scheduled retrofit can leave a facility without a critical spare for nearly two years if ordered new from the factory. For engineers managing aging drives or legacy inverter platforms, sourcing from a stocking distributor is not just convenient — it is operationally essential. ATI maintains inventory of hard-to-find and long-lead-time IGBT modules precisely for these situations.

ATI Accurate Technology is located in Palmetto, Florida and ships same-day on orders placed before 5PM EST. We stock new OEM IGBT modules, thyristors, diodes, and rectifier assemblies including obsolete and long-lead-time parts. Volume pricing is available.
