The IXYS MDD72-14N1B is a dual diode module rated for 72A average output current and a 1400V repetitive peak reverse voltage (VRRM). Built on IXYS's proven power module platform, this component delivers low forward voltage drop and high thermal cycling capability in a compact, isolated baseplate package. It is engineered to meet the rigorous demands of industrial rectification, freewheeling, and snubber circuit applications where thermal performance and long-term reliability are non-negotiable. The standard screw-terminal and baseplate construction simplifies integration into existing drive and converter designs.

The MDD72-14N1B is well suited for AC/DC front-end rectifier stages, regenerative DC motor drives, UPS systems, induction heating equipment, and mid-voltage industrial power supplies. Its 1400V voltage class provides the necessary derating margin for 690VAC line-connected systems, while the 72A current rating handles sustained load currents found in medium-power industrial converters. Engineers specifying replacements for aging drive cabinets or designing new power assemblies will find this module compatible with a broad range of IXYS and equivalent competitor footprints.

Key Features of the MDD72-14N1B:

• 1400V VRRM rating provides robust derating margin for 690VAC three-phase line applications
• 72A average forward current (IFAV) supports sustained operation in medium-power rectifier and freewheeling circuits
• Dual diode configuration in a single isolated baseplate module simplifies PCB layout and busbar assembly
• Low forward voltage drop (VF) minimizes conduction losses and reduces heat sink requirements
• Electrically isolated baseplate enables direct mounting to heat sinks without additional insulation pads in most configurations
• Compatible with standard IXYS MDD-series mounting footprints, facilitating drop-in replacement in existing assemblies

With a factory lead time of 36 weeks on new production, the MDD72-14N1B presents a significant procurement challenge for maintenance teams managing unplanned downtime or engineers building new assemblies against tight project schedules. IXYS modules in this voltage and current class are routinely found in aging industrial equipment where the original manufacturer no longer maintains buffer stock. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time IXYS diode modules specifically to bridge this gap, providing verified new OEM parts without the extended factory wait.
