The Fuji 2DI30A-120 is a dual diode module offering a 30A continuous current rating and a 1200V repetitive peak reverse voltage (VRRM), packaged in Fuji's established low-inductance module platform. Designed for demanding rectification and freewheeling applications, this module integrates two discrete diodes in a single isolated package, reducing assembly complexity while maintaining the thermal and electrical performance required in industrial-grade power electronics. The isolated baseplate allows direct mounting to a heatsink without additional electrical isolation hardware, streamlining system integration in both OEM designs and field replacements.

The 2DI30A-120 is well suited for a broad range of industrial power conversion applications, including three-phase bridge rectifiers, DC bus clamping, freewheeling circuits in motor drives, and input rectification stages in UPS systems and switched-mode power supplies. Its 1200V blocking voltage provides adequate headroom for 690V AC line inputs with appropriate derating, while the 30A current rating covers a wide range of mid-power drive and converter platforms. Industries relying on this module include material handling, HVAC, CNC machinery, elevator drives, and renewable energy inverter systems.

Key Features of the 2DI30A-120:

• 1200V VRRM provides robust voltage blocking margin for 480V and 690V AC input applications
• 30A average forward current (IF(AV)) supports mid-range motor drive and converter topologies
• Dual diode configuration in a single isolated module reduces component count and simplifies thermal management
• Isolated copper baseplate enables direct heatsink mounting without supplemental insulation hardware
• Low forward voltage drop (VF) minimizes conduction losses and improves overall system efficiency
• Compatible with standard Fuji 2DI-series mounting footprints, facilitating drop-in replacement of legacy assemblies

With a factory lead time of 99 weeks for new production, the 2DI30A-120 presents a significant procurement challenge for maintenance teams managing unplanned downtime or project schedules that cannot accommodate nearly two-year waits. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time Fuji power semiconductor modules specifically to address these gaps. Whether you need a single module for emergency repair or a larger quantity to secure your MRO stock, ATI can fulfill orders from available inventory without the delays inherent in factory scheduling cycles.
