The Sanrex DF200FA80 is a robust diode module engineered for high-power rectification duties in industrial drives, power supplies, and converter systems. Rated at 200A continuous forward current and 800V repetitive peak reverse voltage, this module delivers the thermal stability and switching reliability that demanding AC-to-DC conversion circuits require. Its compact, industry-standard module footprint simplifies drop-in replacement in existing equipment designs, making it a critical stocking item for maintenance and repair operations dependent on Sanrex power semiconductor platforms.

The DF200FA80 sees widespread deployment across industrial variable frequency drives, UPS systems, welding power supplies, induction heating converters, and regenerative braking units in crane and elevator control systems. Its 800V blocking capability provides adequate voltage margin in 480VAC three-phase input stages, while the 200A current rating supports mid-to-large frame drive topologies. OEM machine builders and aftermarket repair facilities servicing legacy Sanrex-based equipment rely on this module to restore full system operation with a verified, specification-matched component rather than a potentially incompatible substitute.

Quick Reference: DF200FA80

Key Features of the DF200FA80:

• 200A average forward current rating suitable for medium-to-high power rectifier stages
• 800V repetitive peak reverse voltage (VRRM) providing robust margin on 480VAC three-phase input rails
• Low forward voltage drop for reduced conduction losses and improved thermal efficiency in continuous-duty cycles
• Isolated copper baseplate construction enabling direct heatsink mounting with standard thermal interface materials
• Industry-standard module package with dual screw-terminal inputs compatible with Sanrex and equivalent-footprint mounting hardware
• Optimized for both single-way and bridge rectifier configurations in industrial converter assemblies

The DF200FA80 was discontinued by Sanrex, and new factory production carries a 99-week lead time — effectively placing replacement units beyond reach for any urgent repair or scheduled maintenance window. For facilities managing legacy drives, power supplies, or custom converter systems built around this module, waiting on new production is rarely a viable option. Procuring from a stocked distributor with verified new OEM inventory is the only practical path to minimizing equipment downtime and keeping critical production assets operational on your schedule rather than a manufacturer's backlog timeline.
