The Fuji 6MBI75S-120-01 is a 1200V, 75A 6-pack IGBT module from Fuji Electric's S-series power module lineup. This device integrates six IGBT switches with co-packed freewheeling diodes in a single housing, enabling a complete three-phase inverter bridge in a space-optimized footprint. Designed for switching frequencies common in industrial drive applications, the 6MBI75S-120-01 offers low saturation voltage (V_CE(sat)), fast recovery diode characteristics, and an isolated baseplate for straightforward heatsink mounting. It is a direct replacement consideration in legacy and current-generation variable frequency drive (VFD) platforms.

The 6MBI75S-120-01 is widely deployed in AC motor drives, servo amplifiers, UPS systems, solar inverters, and industrial power conditioning equipment operating at medium power levels. Its 1200V blocking voltage provides the necessary headroom for 480V and 690V AC bus systems, while the 75A continuous rating covers a broad range of motor control platforms from roughly 30 to 55 kW. The module is also found in regenerative drives, crane and hoist control systems, injection molding equipment, and HVAC compressor drives where reliable, compact IGBT switching is essential.

Key Features of the 6MBI75S-120-01:

• 1200V V_CES rating provides robust voltage margin for 480V and 690V three-phase systems
• 75A continuous collector current supports medium-power drive and inverter topologies up to approximately 55 kW
• 6-pack configuration integrates a full three-phase IGBT inverter bridge with co-packed freewheeling diodes in one module
• Low V_CE(sat) characteristic reduces conduction losses and improves overall system efficiency at rated load
• Isolated copper baseplate enables direct heatsink mounting without additional isolation hardware, simplifying thermal management
• Industry-standard pinout and package footprint compatible with common Fuji S-series mounting configurations for drop-in serviceability

With a factory lead time of 99 weeks on new production, the 6MBI75S-120-01 presents a serious supply chain risk for maintenance operations, OEM production lines, and repair depots that cannot afford extended downtime or procurement delays. Fuji IGBT modules in this class are frequently discontinued or placed on long allocation, making distributor stock the only practical source for timely fulfillment. ATI maintains inventory of hard-to-find and long-lead-time power semiconductors precisely for these situations, providing engineers and buyers with immediate access to parts that are otherwise unavailable through standard distribution channels.
