The Fuji 2MBI300S-120 is a 300A, 1200V dual IGBT module engineered for demanding power conversion environments. Its dual half-bridge configuration integrates two IGBT switches with freewheeling diodes in a single package, reducing board footprint while simplifying thermal management. The 1200V blocking voltage and 300A continuous current rating place this module squarely in the high-power tier, making it suitable for three-phase inverter legs, AC motor drives, and regenerative braking circuits where switching efficiency and ruggedness are non-negotiable design requirements.

The 2MBI300S-120 sees wide deployment across industrial and infrastructure applications including variable frequency drives (VFDs) for large AC induction and permanent magnet motors, UPS systems, solar inverters, traction converters, and medium-voltage servo amplifiers. Its robust current and voltage ratings make it a reliable choice for OEM equipment manufacturers building high-cycle-count machinery as well as maintenance teams performing like-for-like replacements in CNC machining centers, press drives, crane hoists, and HVAC compressor systems where unplanned downtime carries significant operational cost.

Key Features of the 2MBI300S-120:

• 1200V collector-emitter voltage (VCES) with 300A continuous collector current rating for high-power inverter and converter stages
• Dual IGBT configuration with integrated co-pack freewheeling diodes, minimizing external component count and parasitic inductance in the commutation loop
• Low saturation voltage (VCE(sat)) characteristic of Fuji's S-series trench-gate IGBT process, reducing conduction losses at rated current
• Isolated baseplate construction supports standard direct-mounting to heatsink or liquid-cooled cold plate, simplifying thermal interface design
• Symmetrical dual package layout facilitates direct use as a single inverter phase leg or parallel operation for higher current outputs
• Compatible with standard Fuji module footprints, enabling drop-in replacement across multiple generations of industrial drive equipment

With a factory lead time of 99 weeks for new production, the 2MBI300S-120 represents exactly the kind of long-lead-time, hard-to-source component that can stall a production line or delay a critical repair. Procurement teams relying solely on the original manufacturer's pipeline face extended equipment downtime and costly project delays. ATI Accurate Technology maintains independent stock of modules like the 2MBI300S-120 specifically to bridge these supply gaps, providing verified new OEM parts when and where the standard supply chain cannot deliver on acceptable timelines.

ATI Accurate Technology is a power semiconductor distributor based in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules including obsolete and long-lead-time parts.
