The Fuji 6MBI25L-120 is a 1200V, 25A six-pack IGBT module engineered for demanding three-phase power conversion applications. Built on Fuji's proven low-loss IGBT technology, this module integrates six IGBT switches and six co-packed freewheeling diodes into a single housing, simplifying board design and reducing component count. The 6-pack configuration enables a complete three-phase inverter bridge in one module, delivering consistent switching characteristics, low V_CE(sat), and reliable short-circuit withstand capability required in industrial power electronics designs.

The 6MBI25L-120 is a natural fit for three-phase variable frequency drives (VFDs), servo drive amplifiers, UPS systems, and regenerative inverters operating at 400–690VAC line voltages. Its 1200V blocking voltage provides the necessary derating margin for industrial mains, while the 25A current rating addresses a wide range of fractional-to-mid-horsepower motor control platforms. The module is also deployed in solar inverters, welding power supplies, and induction heating equipment where compact, high-efficiency switching is essential.

Key Features of the 6MBI25L-120:

• 1200V V_CES rating delivers adequate voltage margin for 400–690VAC three-phase industrial applications
• 6-pack topology integrates a complete three-phase inverter bridge — six IGBTs plus six fast-recovery freewheeling diodes — in a single isolated module
• Low V_CE(sat) characteristic minimizes conduction losses, improving system efficiency across the full load range
• Defined short-circuit withstand time (t_SC) supports hardware overcurrent protection schemes in drive and inverter designs
• Electrically isolated baseplate simplifies thermal management and allows direct mounting to heatsinks without additional insulation hardware
• Industry-standard pin and mounting configuration eases drop-in replacement for equivalent 6-pack modules in existing drive platforms

With a current factory lead time of 99 weeks for new production, the 6MBI25L-120 presents a serious procurement challenge for OEMs managing production schedules and MRO teams facing unplanned equipment downtime. A single failed module in a VFD or servo drive can halt an entire production line for months if purchasing decisions are delayed. Sourcing from a distributor with verified, in-stock OEM inventory is the only reliable strategy to avoid extended operational disruption. ATI maintains stock of long-lead-time and hard-to-find Fuji IGBT modules specifically to bridge this supply gap.
