The Infineon DDB6U100N12RR is a three-phase bridge rectifier diode module rated for 100A average output current and a 1200V repetitive peak reverse voltage (VRRM). Housed in a standard power module package, it integrates six diodes in a B6 bridge topology, eliminating discrete component assembly and reducing system inductance. Its robust silicon construction, optimized thermal interface, and isolated baseplate make it a reliable choice for designers who need proven rectification performance in space-constrained industrial drives and power supply platforms.

The DDB6U100N12RR sees widespread deployment in AC variable-speed drives, soft starters, uninterruptible power supplies (UPS), industrial welding equipment, and regenerative DC bus systems. Its 1200V blocking capability provides the necessary headroom for 690VAC line inputs with transient margin to spare, while the 100A current rating suits mid-range drive platforms from fractional to multi-kilowatt output. The module is equally at home in DC motor controllers, elevator drives, crane hoists, and industrial power conditioning equipment where front-end rectification integrity is non-negotiable.

Quick Reference: DDB6U100N12RR

Key Features of the DDB6U100N12RR:

• B6 three-phase bridge topology with six integrated diodes in a single isolated-baseplate module
• 1200V VRRM blocking voltage providing robust transient margin on 480V and 690VAC systems
• 100A average forward current (IFAV) supporting mid-to-high power industrial drive front ends
• Low forward voltage drop (VF) optimized to minimize conduction losses and reduce heatsink thermal load
• Isolated copper baseplate enabling direct heatsink mounting without additional isolation hardware
• Industry-standard footprint ensuring drop-in compatibility with existing PCB and busbar layouts

With a factory lead time of 99 weeks from Infineon, procurement teams relying solely on the standard supply chain face serious production exposure. End-of-life and allocation risk compound the challenge for maintenance shops needing a single unit to return a critical drive to service. ATI Accurate Technology maintains independent stock of hard-to-find and long-lead-time power semiconductors precisely for these situations. Whether you need one module for emergency repair or a buffer quantity to protect a multi-site maintenance program, ATI can fulfill from verified new OEM inventory without the multi-year wait.

ATI Accurate Technology is located in Palmetto, Florida, and ships same-day on orders received before 5PM EST. We specialize in IGBTs, diodes, thyristors, and rectifier modules—including obsolete and allocation-constrained parts the market can't readily supply.
