The Fuji 1DI300D-100 is a single-configuration power diode module rated for 300A continuous forward current and a 1000V repetitive peak reverse voltage (VRRM). Built to Fuji Electric's established power module standards, this device delivers stable rectification performance under high-load conditions, with a low forward voltage drop that minimizes conduction losses in high-current circuits. The isolated base plate construction simplifies heatsink mounting and thermal management, making this module a dependable choice for engineers who require consistent performance in continuous-duty power conversion applications.

The 1DI300D-100 is well suited for industrial AC-to-DC rectification stages, field-excitation supplies, battery charging systems, DC bus rectifiers, and regenerative drive front ends. Its 300A current capability supports heavy-duty equipment such as large AC and DC motor drives, industrial welding power supplies, induction heating systems, and UPS front-end rectifiers. Wherever reliable unidirectional current flow and robust reverse-voltage blocking are required in a thermally manageable module format, the 1DI300D-100 is a proven and widely specified solution across multiple industrial sectors.

Key Features of the 1DI300D-100:

• 300A average forward current (IFAV) rating for high-power rectification duty cycles
• 1000V repetitive peak reverse voltage (VRRM) providing margin against line transients and voltage spikes
• Single diode configuration enabling flexible circuit integration into bridge, half-wave, or custom rectifier topologies
• Isolated copper base plate for direct heatsink mounting, supporting efficient thermal dissipation in continuous-duty operation
• Low forward voltage drop (VF) minimizes conduction losses and reduces heat generation in high-current applications
• Standard Fuji module footprint simplifies drop-in replacement of legacy assemblies and reduces redesign effort

With a factory lead time of 99 weeks for new production, the 1DI300D-100 presents a significant procurement challenge for maintenance teams and OEM production schedules alike. Extended lead times at this level effectively make the part allocation-critical, and sourcing from distribution inventory is often the only viable path to avoiding costly equipment downtime or production delays. ATI Accurate Technology maintains stock of hard-to-find and long-lead-time Fuji power modules precisely to bridge this gap, providing a reliable supply chain alternative when factory channels cannot meet your timeline.
