The Fuji Electric 2MBI75S-120-03 is a 1200V, 75A dual IGBT module built for demanding industrial switching applications. Based on Fuji's S-series IGBT technology, this module integrates two IGBT switches with freewheeling diodes in a single compact package, reducing board space and simplifying thermal management. Engineered for high switching frequency operation with low saturation voltage, the 2MBI75S-120-03 delivers the efficiency and ruggedness required in continuous-duty industrial environments where thermal cycling and transient voltage stress are constant concerns.

The 2MBI75S-120-03 is widely deployed in AC motor drive inverter stages, regenerative braking systems, industrial UPS and backup power converters, induction heating equipment, and servo amplifier output stages. Its 1200V blocking voltage provides necessary headroom for 480V and 690V AC bus applications, while the 75A continuous rating supports mid-range drive platforms. The dual configuration directly replaces a two-switch inverter leg, making it a practical choice for OEM board-level designs and field replacements in aging drive systems across manufacturing, oil and gas, and material handling industries.

Key Features of the 2MBI75S-120-03:

• Dual IGBT configuration with integrated freewheeling diodes for inverter leg replacement in a single module
• 1200V collector-emitter voltage (VCES) provides robust margin for 480V and 690V three-phase bus applications
• 75A continuous collector current (IC) suitable for mid-range industrial motor drive and power conversion platforms
• Low VCE(sat) characteristic reduces conduction losses and minimizes heat sink requirements in space-constrained designs
• Isolated baseplate construction simplifies thermal interface to heat sink without additional electrical isolation hardware
• Compatible with standard Fuji S-series footprint, enabling direct board-level substitution in existing OEM equipment

The 2MBI75S-120-03 is officially obsolete with no active production at Fuji Electric, and current factory lead times for equivalent new production parts extend to 99 weeks or longer. For maintenance teams managing aging drive systems or procurement professionals sourcing for MRO inventory, waiting on factory allocation is rarely an option. ATI Accurate Technology sources and stocks obsolete and long-lead-time IGBT modules precisely for these situations, providing verified new OEM parts from traceable supply chains so you can complete repairs and avoid extended downtime.
