The IXYS MDD56-16N1B is a robust diode module engineered for high-voltage, high-current rectification duty in industrial and commercial power conversion equipment. Rated at 56A continuous forward current and a 1600V repetitive peak reverse voltage (VRRM), this module is built on IXYS's proven isolation substrate technology, offering reliable thermal management and low forward voltage drop. Its compact module format simplifies PCB and heatsink integration, reducing assembly complexity in both OEM production builds and field replacement scenarios.

The MDD56-16N1B is well suited for AC/DC front-end rectifiers, freewheeling diode positions in motor drive inverters, regenerative braking circuits, UPS systems, and welding power supplies. Industries including industrial automation, renewable energy, material handling, and heavy-duty HVAC equipment routinely depend on high-voltage diode modules of this class to maintain uptime under continuous load cycling. Its 1600V voltage class provides the necessary margin for line-connected applications operating from 690VAC and three-phase industrial distribution networks where voltage transients are a concern.

Key Features of the MDD56-16N1B:

• 1600V repetitive peak reverse voltage (VRRM) provides robust margin for 690VAC and transient-heavy industrial environments
• 56A average forward current rating supports continuous-duty rectification and freewheeling in high-power drive topologies
• Low forward voltage drop (VF) minimizes conduction losses and reduces thermal stress on the heatsink interface
• Isolated baseplate construction allows direct mounting to a common heatsink without additional insulation hardware, simplifying thermal design
• Module package format offers low-inductance internal connections, improving switching performance and reducing EMI in fast-switching applications
• Manufactured to IXYS quality standards with controlled lot traceability, suitable for both new equipment builds and critical maintenance replacements

With a factory lead time of 34 weeks on new production orders, procurement teams sourcing the MDD56-16N1B for planned maintenance, safety stock replenishment, or emergency line-down situations cannot afford to rely on direct factory channels alone. IXYS diode modules in the MDD series have a long service history, meaning fielded equipment needing repairs may encounter extended waits or discontinued availability through standard distribution. Stocking distributors with verified OEM inventory are the practical solution for engineers who need to keep production running without committing to a 34-week timeline.
