The Fuji 6RI100G-120 is a 6-pulse, 3-phase diode rectifier module rated for 100A average output current and a 1200V repetitive peak reverse voltage. Configured as a full three-phase bridge internally, it converts three-phase AC line power to DC in a single, self-contained module. The 6RI100G-120 is engineered for high thermal reliability, with an isolated base plate allowing direct mounting to a heatsink without additional insulation hardware. It is a drop-in solution for industrial rectification stages requiring proven, repeatable performance under continuous load conditions.

The 6RI100G-120 is well suited for industrial variable frequency drives, DC bus power supplies, servo amplifiers, welding equipment, and regenerative braking systems. Its 1200V blocking voltage provides the necessary voltage margin for 480V and 690V three-phase input systems, while the 100A current rating supports medium-power drive and power supply designs in the range of 30–75kW and beyond depending on thermal management. It is also commonly found in UPS front-end rectifiers, crane and hoist drives, and industrial battery charging systems where robust, long-service-life rectification is required.

Key Features of the 6RI100G-120:

• 100A average forward current (IFAV) with 1200V repetitive peak reverse voltage (VRRM) for 480V/690V three-phase applications
• 6-pulse, 3-phase full-bridge internal diode configuration — no external bridge assembly required
• Isolated copper base plate for direct heatsink mounting, simplifying thermal interface design
• Low forward voltage drop across rectifier diodes minimizes conduction losses and reduces heatsink sizing requirements
• Compact, industry-standard module footprint compatible with common heatsink form factors used across Fuji and equivalent competitor platforms
• Designed for continuous duty in high-ambient industrial environments with strong resistance to thermal cycling fatigue

The 6RI100G-120 carries a factory lead time of 99 weeks on new production orders — nearly two years. For OEMs managing production schedules, equipment manufacturers supporting installed bases, and maintenance teams facing unplanned downtime, that lead time is operationally unacceptable. Sourcing from a stocking distributor like ATI is not just a convenience — it is the only viable path to keeping equipment running or production lines on schedule. Obsolescence risk is also a real concern with established module platforms, making in-stock inventory even more valuable. ATI maintains verified new OEM stock of the 6RI100G-120 for immediate fulfillment.
