The Fuji 6RI75G-120 is a three-phase, 6-pulse rectifier bridge module rated for 75A average output current and 1200V repetitive peak reverse voltage. Engineered for high-efficiency AC-to-DC conversion, this module integrates six rectifier diodes in a standard full-bridge configuration within a single isolated package. Its robust construction supports operation in thermally demanding environments, making it a reliable front-end rectification solution for industrial power electronics where continuous duty cycles and tight electrical tolerances are non-negotiable.

The 6RI75G-120 is widely deployed as the DC bus front-end in variable frequency drives (VFDs), servo drive systems, regenerative braking units, welding inverters, and industrial UPS platforms. It is equally suited for DC power supplies in machine tool controls, crane and hoist drives, and elevator traction systems — any application where a rugged, proven three-phase rectifier module must handle sustained load currents up to 75A at medium-high bus voltages without compromise to thermal or electrical performance.

Key Features of the 6RI75G-120:

• Three-phase full-wave 6-pulse rectifier topology providing low output ripple and high power factor on the AC input side
• 1200V VRRM rating delivers ample voltage margin for 480VAC three-phase line inputs with transient overvoltage headroom
• 75A average output current capacity supports continuous heavy-duty industrial load profiles without derating under proper thermal management
• Isolated baseplate construction allows direct mounting to heatsink or cold plate, simplifying thermal interface design and system integration
• Compact single-package integration of six diodes reduces PCB footprint, bill of materials complexity, and assembly labor versus discrete diode configurations
• Manufactured to Fuji Electric quality standards with controlled forward voltage drop characteristics for predictable conduction losses across the operating temperature range

With a factory lead time of 99 weeks for new production, the 6RI75G-120 represents a serious procurement challenge for OEMs managing production schedules and MRO teams facing unplanned equipment failures. Extended lead times of this magnitude are increasingly common across power semiconductor product lines as foundry capacity remains constrained. Sourcing from a stocking distributor is often the only viable path to avoid costly downtime or line stoppages. ATI maintains inventory of hard-to-find and long-lead-time modules precisely for these situations, providing immediate access when the factory cannot.

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