The Fuji 2MBI300N-120 is a dual IGBT module rated for 300 amperes continuous collector current and 1200 volts collector-emitter voltage. Built to Fuji Electric's N-series platform, this module integrates two IGBT switches with freewheeling diodes in a compact dual configuration, delivering the switching performance and thermal efficiency required in demanding power conversion topologies. Its robust construction supports high-frequency operation while maintaining low switching losses, making it a proven solution for engineers who need reliable performance in high-power density designs.

The 2MBI300N-120 has been widely deployed across industrial and commercial power electronics platforms. Typical applications include three-phase AC motor drives and variable frequency drives (VFDs), industrial UPS and energy storage inverters, induction heating systems, welding power supplies, servo drive amplifiers, and traction control systems. The module's 1200V blocking voltage and 300A current rating position it squarely in the mid-to-high power range where system designers require both ruggedness and switching efficiency in a standardized footprint.

Key Features of the 2MBI300N-120:

• Dual IGBT configuration with integrated freewheeling diodes for simplified half-bridge or phase-leg implementation
• 1200V collector-emitter voltage (VCES) with 300A rated continuous collector current (IC)
• Low saturation voltage (VCE(sat)) characteristic of Fuji N-series IGBTs, minimizing conduction losses at full load
• Optimized for switching frequencies up to 20kHz, suitable for PWM-controlled drive applications
• Isolated baseplate construction enabling direct mounting to heatsink without additional insulation hardware
• Industry-standard module footprint compatible with existing Fuji N-series drive platforms and PCB layouts

The 2MBI300N-120 has been discontinued by Fuji Electric, with new factory production orders currently reflecting lead times of 99 weeks or greater — effectively placing it beyond reach for most maintenance and production schedules. For OEMs supporting legacy equipment and maintenance teams managing unplanned downtime, locating verified new stock has become the primary challenge. Purchasing from distributors holding certified OEM inventory is the most reliable path to avoiding counterfeit exposure and ensuring the module performs to original datasheet specifications in your application.
