The Fuji 1DI150GF-100 is a single-phase diode module delivering a 150A continuous current rating and 1000V repetitive peak reverse voltage (VRRM). Built to Fuji Electric's established power semiconductor standards, this module integrates high-efficiency rectifier diodes within an isolated baseplate package, minimizing stray inductance and simplifying heatsink mounting. It is engineered for continuous duty in high-power industrial environments where thermal stability, low forward voltage drop, and reliable reverse blocking are non-negotiable requirements. The 1DI150GF-100 is a direct replacement candidate in legacy Fuji-based drive and power supply platforms.

The 1DI150GF-100 is well suited for industrial AC-DC rectification stages, regenerative motor drive front ends, crane and hoist power systems, welding power supplies, and uninterruptible power supply (UPS) charger circuits. Its 1000V voltage class provides adequate margin for 480V and 600V three-phase line voltages after accounting for transient overvoltages. Facilities managing press lines, extruders, conveyors, and other continuous-process equipment frequently rely on this class of diode module to maintain uptime in demanding production environments where component failure carries significant downtime costs.

Quick Reference: 1DI150GF-100

Key Features of the 1DI150GF-100:

• 150A average forward current (IF(AV)) rating for high-power rectification duty cycles
• 1000V repetitive peak reverse voltage (VRRM) providing robust margin on 480V and 600V bus systems
• Low forward voltage drop (VF) reduces conduction losses and heatsink thermal load in continuous operation
• Isolated copper baseplate construction enables direct heatsink mounting without additional isolation hardware
• Compact module footprint compatible with standard Fuji GF-series mechanical interfaces and existing drive chassis designs
• Designed for high surge current capability (IFSM), protecting against line transients and capacitive inrush events at startup

With a factory lead time of 99 weeks on new production orders, the 1DI150GF-100 is effectively unavailable through standard distribution channels for any application requiring near-term repair or system build. For OEMs maintaining legacy Fuji drive platforms and MRO teams supporting installed equipment, waiting nearly two years for a replacement module is not operationally acceptable. ATI Accurate Technology maintains ready inventory of the 1DI150GF-100 precisely to bridge this gap, providing verified new OEM stock when the factory pipeline cannot respond in time to keep critical equipment running.
