The Fuji 6MBI180VX-120-55 is a 6-in-1 IGBT module configured as a three-phase inverter bridge, rated for 180A continuous collector current and 1200V collector-emitter voltage. Built on Fuji's VX-series platform, this module integrates six IGBT chips with fast-recovery freewheeling diodes in a compact, isolated baseplate package. The design targets low switching loss and stable thermal performance under continuous load cycling, making it well suited for demanding industrial environments where reliability and switching efficiency are non-negotiable. Its integrated topology reduces external component count and simplifies gate drive design.

The 6MBI180VX-120-55 is deployed across a wide range of industrial power electronics applications, including variable frequency drives (VFDs), AC servo amplifiers, elevator traction inverters, uninterruptible power supplies (UPS), induction heating systems, and industrial welding equipment. The 1200V blocking voltage and 180A current rating place it in the mid-to-high power class suitable for motor drives in the 30–75kW range. Its three-phase bridge configuration makes it a direct fit for retrofit and repair of legacy drive systems originally designed around the Fuji VX IGBT platform.

Key Features of the 6MBI180VX-120-55:

• 180A continuous collector current (Ic) with 1200V collector-emitter voltage (VCES) for robust mid-to-high power inverter designs
• 6-in-1 three-phase inverter bridge configuration with integrated freewheeling diodes, minimizing external circuit complexity
• VX-series low-loss IGBT technology optimized for reduced switching losses at moderate to high switching frequencies
• Isolated copper baseplate for direct heatsink mounting, supporting efficient thermal management in enclosed drive enclosures
• Low saturation voltage (VCE(sat)) characteristics reduce conduction losses during continuous duty operation
• Compatible with standard Fuji 6MBI-series gate drive circuits, enabling drop-in replacement in existing drive platforms without redesign

The 6MBI180VX-120-55 has been discontinued by Fuji Electric, with any new factory production carrying a 99-week lead time — effectively making it unavailable through standard distribution channels. For maintenance engineers managing aging drive systems or procurement teams supporting installed base equipment, waiting nearly two years for factory delivery is not a viable option. Field failures, planned maintenance windows, and drive retrofits all demand access to critical IGBT modules now. ATI Accurate Technology maintains independent inventory of obsolete and long-lead-time Fuji IGBT modules specifically to support these scenarios.
