The Fuji 1MBH25-120 is a single-configuration Insulated Gate Bipolar Transistor (IGBT) module offering a 25A continuous collector current rating and a 1200V collector-emitter voltage (VCES) rating. Built to Fuji Electric's established power module standards, this device combines the high input impedance of a MOSFET gate with the low saturation voltage characteristics of a bipolar transistor — delivering efficient, high-frequency switching performance in a thermally manageable package. The 1200V voltage class makes it appropriate for applications powered from three-phase AC mains where elevated DC bus voltages are present.

The 1MBH25-120 sees broad use across industrial power electronics, particularly in variable frequency drives (VFDs), servo amplifiers, and medium-power inverter stages. Its single-switch configuration gives design engineers and field service teams flexibility when replacing discrete switch positions within multi-phase bridge assemblies or when building custom converter topologies. Additional applications include UPS systems, induction heating equipment, welding inverters, and auxiliary power supplies in industrial automation environments where reliable switching at elevated voltages is non-negotiable.

Key Features of the 1MBH25-120:

• 1200V VCES rating supports operation on 480V three-phase AC bus architectures with appropriate derating margin
• 25A continuous collector current (IC) in a single-switch module configuration for flexible circuit integration
• Low gate charge and high input impedance enable straightforward drive circuit design with standard IGBT gate drivers
• Isolated baseplate construction allows direct heatsink mounting without additional insulation hardware, simplifying thermal management
• Low VCE(sat) characteristic reduces conduction losses, improving overall inverter and converter efficiency at operating load
• Fuji Electric OEM construction ensures dimensional and electrical interchangeability with original equipment specifications

The 1MBH25-120 carries a factory lead time of 99 weeks for new production orders — a reality that creates significant risk for maintenance operations and active production lines alike. When a drive or inverter goes down, waiting nearly two years for a factory shipment is not a viable option. Procurement teams managing MRO inventory and engineers supporting legacy equipment increasingly turn to stocking distributors who carry genuine OEM parts on the shelf. Sourcing from a reliable distributor with verified new stock eliminates lead time risk and keeps critical systems running without extended downtime.
