The Fuji 2DI75Z-120 is a dual diode power module rated for 75A continuous forward current and 1200V repetitive peak reverse voltage. Built to Fuji's established Z-series module platform, this device integrates two high-voltage diode dies within a single isolated base package, delivering low forward voltage drop, strong surge current capability, and the thermal performance required in demanding industrial power electronics environments. The isolated copper baseplate enables direct mounting to heatsinks, simplifying thermal management in densely packaged drive and converter assemblies.

The 2DI75Z-120 is widely deployed in AC motor drive front-end rectifier stages, regenerative braking circuits, UPS systems, welding power supplies, and induction heating equipment. Its 1200V blocking voltage provides the necessary derating margin when operating from 480V or 690V AC mains, while the 75A current rating addresses mid-power drive platforms in the 15–37kW range. OEM and field service engineers rely on this module as a standard building block in three-phase bridge and boost rectifier topologies across process automation, material handling, and energy conversion applications.

Quick Reference: 2DI75Z-120

Key Features of the 2DI75Z-120:

• Dual diode configuration in a single isolated-base module package reduces component count and simplifies PCB or busbar layout
• 1200V repetitive peak reverse voltage (VRRM) provides reliable derating margin on 480V and 690V three-phase systems
• 75A average forward current (IFAV) supports mid-range industrial drive and rectifier designs in the 15–37kW power class
• Low forward voltage drop minimizes conduction losses and reduces heatsink thermal requirements at rated load
• High surge current (IFSM) rating accommodates capacitive inrush and fault transient conditions common in drive front-end circuits
• Isolated copper baseplate construction allows direct heatsink mounting with standard thermal interface materials, compatible with existing Z-series mechanical footprints

With a current factory lead time of 99 weeks, the 2DI75Z-120 represents exactly the type of long-lead, production-constrained component that creates unplanned downtime risk for maintenance and procurement teams. Fuji Z-series modules are deeply embedded in legacy and current-generation drives from multiple OEMs, meaning demand consistently outpaces production availability. Sourcing from a stocking distributor is the only practical strategy for emergency repairs or planned production builds that cannot wait two years for factory fulfillment. ATI maintains inventory of the 2DI75Z-120 specifically to bridge this gap for industrial customers.
