The Fuji 2DI100M-120 is a dual-configuration diode module rated for 100A continuous forward current and 1200V repetitive peak reverse voltage. Built to Fuji Electric's industrial-grade standards, this module integrates two diodes in a common isolated base package, delivering reliable rectification performance with low forward voltage drop and excellent thermal characteristics. The 1200V blocking capability provides substantial margin in DC bus applications, while the robust module construction ensures mechanical integrity under the thermal cycling conditions typical of continuous industrial duty.

The 2DI100M-120 is well suited for AC-to-DC rectification stages in variable frequency drives, regenerative converters, UPS systems, welding power supplies, and industrial servo amplifiers. Its dual-diode topology is commonly deployed in boost PFC front ends, freewheeling configurations, and three-phase bridge rectifier assemblies where modular construction reduces assembly time and improves serviceability. The 1200V/100A class is a workhorse rating across heavy industrial equipment, elevator drives, and process control power stages where reliability and consistent switching characteristics are non-negotiable.

Key Features of the 2DI100M-120:

• Dual diode configuration in a single isolated base module for simplified circuit integration and reduced component count
• 1200V repetitive peak reverse voltage (VRRM) with substantial design margin for transient-heavy industrial environments
• 100A average forward current rating suitable for high-power rectification and freewheeling duty cycles
• Low forward voltage drop minimizes conduction losses and reduces heatsink thermal requirements at rated current
• Isolated copper base plate allows direct heatsink mounting without additional insulation hardware
• Fuji Electric OEM construction ensuring consistent lot-to-lot electrical characteristics and mechanical fit for existing drive platforms

With a current factory lead time of 99 weeks, the 2DI100M-120 is effectively unavailable through standard distribution channels for any application requiring near-term procurement. For maintenance teams facing unplanned equipment downtime or engineers managing safety stock for aging drive platforms, a 99-week lead time is operationally unacceptable. ATI Accurate Technology maintains inventory of exactly these high-demand, long-lead-time Fuji modules, enabling same-day fulfillment for critical repairs and scheduled maintenance programs without waiting on factory production cycles.
