The Fuji 6RI75E-080 is an 800V-rated power semiconductor module from Fuji Electric's established 6RI-series lineup. Engineered for high-reliability operation in industrial environments, this module integrates rectifier bridge topology with robust voltage blocking capability. Its compact, industry-standard package format simplifies drop-in replacement for maintenance and repair scenarios. The 800V voltage rating provides adequate headroom for line-voltage transients common in three-phase AC input systems, making it a proven choice for engineers who need dependable performance in continuous-duty applications without compromise.

The 6RI75E-080 sees broad use across industrial power conversion platforms including AC and DC motor drives, servo amplifiers, uninterruptible power supplies (UPS), welding power supplies, and industrial inverter systems. Its rectifier module architecture suits front-end AC-to-DC conversion stages where thermal stability and consistent forward voltage characteristics are critical to system efficiency. Equipment manufacturers and MRO procurement teams working on legacy drives from brands such as Siemens, ABB, Yaskawa, and Mitsubishi frequently specify this Fuji module as a direct replacement component.

Key Features of the 6RI75E-080:

• 800V repetitive peak reverse voltage (VRRM) rating for robust transient immunity on three-phase AC inputs
• Three-phase bridge rectifier topology integrated into a single isolated base module package
• Thermally efficient substrate design enabling reliable continuous-duty operation at rated current
• Isolated copper base plate construction for direct heatsink mounting with low thermal resistance
• Industry-standard footprint ensures mechanical and electrical interchangeability with equivalent-class modules
• Designed to Fuji Electric's stringent quality and reliability standards for industrial-grade power electronics

The 6RI75E-080 has been discontinued by Fuji Electric, and new factory production carries a lead time of 99 weeks — effectively ruling out OEM procurement for any time-sensitive repair or production need. For maintenance engineers managing aging drive systems and for procurement teams supporting legacy equipment fleets, securing verified open-market stock is the only practical path to avoiding extended machine downtime. ATI Accurate Technology maintains inventory of hard-to-find and obsolete Fuji modules, including the 6RI75E-080, sourced and inspected to support critical MRO and OEM replacement requirements.

ATI Accurate Technology is located in Palmetto, Florida and specializes in obsolete, long-lead-time, and hard-to-find power semiconductors including IGBTs, thyristors, diodes, and rectifier modules.
