The Fuji 1MBI400NN-060 is a single IGBT module rated for 400A continuous collector current and 600V collector-emitter voltage. Built on Fuji's proven NN-series platform, this module integrates a high-speed, low-loss IGBT with a freewheeling diode in a compact single configuration. It is designed for high-efficiency switching at industrial power levels, offering low V_CE(sat) characteristics and robust thermal performance. The 1MBI400NN-060 is well-suited for demanding environments where reliable gate drive response, switching speed, and junction temperature management are non-negotiable design requirements.

The 1MBI400NN-060 sees broad deployment in industrial AC and DC motor drives, regenerative braking systems, UPS inverters, induction heating equipment, and welding power supplies. Its 400A current handling and 600V blocking capability place it in the mid-to-high power range that defines the backbone of factory automation, crane and hoist drives, elevator drive systems, and renewable energy inverters. Engineers specifying replacements for legacy drive systems or designing new power stages will find the electrical and mechanical characteristics of this module align with standard industrial converter topologies.

Key Features of the 1MBI400NN-060:

• 400A collector current (I_C) with 600V collector-emitter voltage (V_CES) in a single IGBT module configuration
• Low V_CE(sat) for reduced conduction losses across the full operating current range
• Integrated co-pack freewheeling diode optimized for fast reverse recovery in hard-switching topologies
• High short-circuit withstand capability suitable for industrial drive fault conditions
• Isolated base plate construction for straightforward thermal interface to heatsink assemblies
• Pin-compatible footprint consistent with Fuji NN-series module standards, simplifying drop-in replacement on existing PCB and busbar layouts

With a factory lead time of 99 weeks for new production, the 1MBI400NN-060 represents exactly the kind of long-lead, hard-to-source component that can halt a production line or delay a project for nearly two years if not proactively managed. Whether you are maintaining an installed base of Fuji-driven equipment, kitting spares for preventive maintenance programs, or managing an MRO inventory for critical machinery, waiting on factory allocation is not a viable strategy. ATI Accurate Technology maintains stock of the 1MBI400NN-060 specifically to bridge this gap for procurement teams and maintenance engineers who cannot afford extended downtime.
