The Fuji 6R1MBI125P-160-54 is a high-voltage IGBT power module rated at 125A and 1600V, engineered for reliable operation in high-power switching and conversion circuits. As part of Fuji's proven MBI-series platform, this module integrates IGBT and freewheeling diode configurations optimized for low switching losses and stable thermal characteristics under continuous industrial duty cycles. Its robust construction and high blocking voltage make it well suited for applications demanding both efficiency and long-term dependability in harsh electrical environments.

The 6R1MBI125P-160-54 is commonly deployed in industrial AC/DC drives, medium-voltage inverters, UPS systems, induction heating equipment, and traction power converters. Its 1600V voltage rating provides the necessary headroom for systems operating from high-voltage DC buses, while the 125A current rating accommodates substantial load demands in motor drive and power supply topologies. Energy infrastructure equipment, welding systems, and regenerative drive platforms also benefit from the thermal and switching performance this Fuji module delivers.

Key Features of the 6R1MBI125P-160-54:

• 1600V collector-emitter voltage (VCES) providing wide safety margin for high-voltage DC bus applications
• 125A continuous collector current rating suitable for heavy industrial load profiles
• Integrated freewheeling diodes optimized for low reverse recovery losses in switching converter topologies
• Low VCE(sat) characteristics reducing conduction losses and improving overall system efficiency
• Isolated baseplate construction for simplified thermal management and heatsink mounting in standard power module assemblies
• Compatible with standard Fuji MBI-series gate drive circuits, simplifying drop-in replacement in existing designs

With a factory lead time of 99 weeks for new production, the 6R1MBI125P-160-54 presents a significant procurement challenge for facilities managing unplanned downtime or production schedules that cannot absorb a two-year sourcing delay. Maintenance engineers and procurement teams requiring immediate replacement units for critical drive or converter repairs cannot rely on standard distribution channels for this part. ATI Accurate Technology specializes in exactly these situations — sourcing hard-to-find, long-lead-time, and obsolete power semiconductors from vetted supply channels to keep operations running without extended delays.

ATI Accurate Technology is located in Palmetto, Florida, and ships same-day on orders received before 5PM EST. Whether you need a single replacement module or volume quantities for a maintenance stockpile, ATI can support your requirements with new OEM product and competitive pricing.
