The Fuji 2MBI100S-120-50 is a 1200V, 100A dual IGBT module from Fuji Electric's S-series platform, engineered for demanding switching applications where low saturation voltage, fast switching characteristics, and reliable thermal performance are essential. Built around Fuji's NPT (Non-Punch-Through) IGBT technology, this module delivers stable switching behavior across a wide temperature range, making it a dependable choice for high-efficiency power conversion in both new designs and legacy equipment maintenance. Its compact form factor and industry-standard pinout simplify integration into existing drive platforms.

The 2MBI100S-120-50 is widely deployed in industrial variable frequency drives (VFDs), AC servo amplifiers, UPS systems, induction heating equipment, and medium-power inverter stages. Its 1200V blocking voltage and 100A continuous current rating make it well-suited for three-phase motor control applications operating from 480V AC bus architectures. Field engineers maintaining older CNC machinery, industrial robotics, and process control drives frequently encounter this module as a direct replacement component where original equipment manufacturers no longer stock spares.

Key Features of the 2MBI100S-120-50:

• 1200V collector-emitter voltage (VCES) with 100A continuous collector current rating
• NPT IGBT chip technology providing positive temperature coefficient for straightforward parallel operation and stable thermal runaway protection
• Low VCE(sat) minimizes conduction losses in continuous-duty industrial inverter applications
• Integrated freewheeling diodes optimized for low reverse recovery loss at elevated switching frequencies
• Industry-standard module footprint and terminal layout compatible with common Fuji S-series drive platforms
• Isolated baseplate construction rated for standard thermal interface mounting to heatsink assemblies

The 2MBI100S-120-50 has been discontinued by Fuji Electric, and new factory production carries a 99-week lead time — effectively making open-market inventory the only practical source for maintenance and repair scenarios. For procurement teams managing MRO spares for legacy drive platforms, waiting nearly two years for factory delivery is not operationally viable. Unplanned downtime on a production line far exceeds the cost of securing verified stock now. ATI sources and maintains inventory of hard-to-find, obsolete, and long-lead-time IGBT modules precisely for situations like this.

ATI Accurate Technology, located in Palmetto, Florida, stocks the 2MBI100S-120-50 and ships same-day on orders received before 5PM EST.
