The Fuji 6DI50M-050 is a three-phase bridge diode module in a 6-pack configuration, delivering a 50A continuous current rating and 500V repetitive peak reverse voltage (VRRM). Housed in a standard isolated baseplate package, this module integrates six diodes in a full-wave bridge topology, eliminating the need for discrete component assembly. It offers low forward voltage drop, high surge current capability, and reliable thermal performance — characteristics that make it a dependable rectification solution in demanding industrial power electronics environments.

The 6DI50M-050 is a proven choice for three-phase front-end rectification stages in AC variable frequency drives (VFDs), servo drive DC bus supplies, uninterruptible power supplies (UPS), soft starters, and industrial welding equipment. Its compact 6-pack footprint simplifies PCB and heatsink layout in retrofit and OEM designs alike. Engineers specifying rectifier modules for motor drive input stages or DC bus charging circuits will find this Fuji module's voltage and current ratings well matched to sub-75kW drive platforms commonly found in process automation and material handling systems.

Quick Reference: 6DI50M-050

Key Features of the 6DI50M-050:

• 6-pack full-wave three-phase bridge configuration — six diodes in a single isolated module
• 50A rated forward current (IFAV) suitable for sub-75kW drive and rectifier applications
• 500V VRRM providing adequate blocking voltage margin on 230V–400V three-phase supply inputs
• Isolated copper baseplate construction for direct heatsink mounting and low thermal resistance (Rth(j-c))
• High non-repetitive surge current (IFSM) rating for robust ride-through during startup and fault conditions
• Industry-standard footprint compatible with existing Fuji and equivalent module heatsink assemblies, simplifying drop-in replacement

With a factory lead time of 99 weeks for new production, the 6DI50M-050 is effectively unavailable through standard distribution channels for any time-sensitive project or repair. For maintenance teams facing a drive-down situation or procurement teams managing long-lead capital spares, waiting two years is not an option. ATI Accurate Technology stocks hard-to-find and long-lead Fuji diode modules precisely for these scenarios — providing immediate access to new OEM inventory when the factory queue cannot support your schedule.

ATI Accurate Technology is located in Palmetto, Florida and specializes in IGBTs, diodes, thyristors, and rectifier modules — including obsolete and long-lead parts like the 6DI50M-050.
