The Fuji 6MBI25LB-120 is a 6-Pack IGBT module integrating six insulated-gate bipolar transistors in a single compact package, rated for 25A continuous collector current and 1200V collector-emitter voltage. Designed around Fuji's LB-series low-loss IGBT technology, this module delivers efficient switching performance suitable for PWM-controlled inverter stages. The integrated six-switch topology — two switches per phase leg — eliminates external bussing between discrete devices, reducing parasitic inductance and simplifying thermal management in space-constrained enclosures.

The 6MBI25LB-120 is well suited for industrial variable-frequency drives (VFDs), servo amplifiers, UPS systems, and solar inverter front-ends where a compact, self-contained three-phase bridge is required. Its 1200V blocking voltage provides the headroom needed when switching 480V AC bus rails under transient conditions, and the 25A current rating targets fractional to low-horsepower motor control stages. This module also sees use in induction heating equipment, welding inverters, and auxiliary power converters across industrial automation platforms.

Key Features of the 6MBI25LB-120:

• 25A / 1200V ratings provide adequate margin for 480V three-phase inverter stages with standard derating practices
• 6-Pack configuration integrates all six switches of a three-phase bridge in a single isolated-base module, reducing assembly complexity
• LB-series low-saturation-voltage IGBT cells minimize conduction losses at typical operating current densities
• Integrated freewheeling diodes co-packaged with each IGBT switch, optimized for soft recovery to reduce EMI and switching stress
• Isolated copper baseplate construction facilitates direct mounting to heatsinks without additional electrical isolation hardware
• Compatible with standard Fuji 6-Pack gate drive ICs and reference drive circuits, simplifying drop-in replacement in existing designs

With a factory lead time of 99 weeks, the 6MBI25LB-120 is effectively unavailable through standard distribution channels on any reasonable procurement timeline. For OEMs managing end-of-life equipment, maintenance teams facing unplanned downtime, or engineers designing around allocated components, waiting nearly two years for new production is not viable. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time Fuji IGBT modules precisely for these situations — providing verified new OEM stock when the factory pipeline offers no practical solution.

ATI Accurate Technology is located in Palmetto, Florida and specializes in IGBTs, thyristors, diodes, and rectifier modules including obsolete and long-lead-time parts.
