The 1MBI2400U4D-170 is a Fuji Electric high-power IGBT module rated for 2400A continuous collector current and 1700V blocking voltage. Built on Fuji's U4D platform, this module integrates IGBT chips with freewheeling diodes in a single robust package optimized for low V_CE(sat), reduced switching losses, and high short-circuit withstand capability. The 1700V voltage class makes it particularly suited for applications operating from high-voltage DC buses where avalanche ruggedness and reliable gate-drive response are non-negotiable design requirements.

This module sees heavy use in industrial medium-voltage variable frequency drives (VFDs), large regenerative servo systems, traction converters, wind turbine pitch and main power converters, utility-scale UPS systems, and high-power induction heating equipment. Anywhere a design demands extreme current density combined with 1700V isolation margins — steel mills, mining equipment, marine propulsion, or grid-tied inverters — the 1MBI2400U4D-170 is a proven solution. Its package footprint and terminal layout are compatible with established Fuji U-series mounting configurations, simplifying drop-in replacement in existing designs.

Key Features of the 1MBI2400U4D-170:

• 2400A collector current rating with 1700V C-E blocking voltage for high-power conversion stages
• U4D-series low V_CE(sat) IGBT chips minimize conduction losses at full load
• Integrated freewheeling diodes with soft recovery characteristics reduce EMI and dV/dt stress on surrounding components
• Short-circuit rated design provides defined withstand time, supporting reliable protection circuit coordination
• High-isolation base plate construction suitable for direct heatsink mounting in forced-air or liquid-cooled assemblies
• Compatible with standard Fuji U-series gate driver references and established drive board footprints

With a published factory lead time of 99 weeks on new production orders, the 1MBI2400U4D-170 is exactly the type of part that brings a production line or critical repair to a standstill when inventory runs dry. Procurement teams managing capital equipment, OEM spare parts programs, or MRO stock for high-power drives should not rely on spot-order scheduling for this device. ATI Accurate Technology maintains ready stock of hard-to-find and long-lead-time IGBT modules specifically to protect customers from these supply chain gaps — with new OEM parts on the shelf today.
