The Fuji 1MBH25D-120 is a single IGBT module delivering a 25A continuous collector current rating at a 1200V blocking voltage. Built to Fuji Electric's established module platform, it incorporates an isolated baseplate construction that supports direct heatsink mounting, enabling efficient thermal dissipation in high-cycle switching environments. The 1200V voltage class makes this device well-suited for applications operating from three-phase 480V AC mains, providing the necessary headroom to absorb inductive transients and commutation spikes without avalanche stress. Engineers familiar with Fuji's 1MBH series will recognize its gate drive compatibility and predictable switching characteristics.

The 1MBH25D-120 is deployed across a broad range of industrial power electronics platforms. Common applications include variable frequency drives (VFDs) for motor speed control in pumping, HVAC, and conveyor systems, as well as inverter stages in UPS systems, welding power supplies, and induction heating equipment. Its 25A current rating positions it in the small-to-mid power range suitable for sub-10kW converter designs. The device is also found in servo drive output stages and auxiliary power inverters where a compact, discrete single-switch module simplifies PCB layout and gate driver isolation requirements.

Key Features of the 1MBH25D-120:

• 1200V VCES blocking voltage with 25A IC continuous current rating — suitable for 480V three-phase line-powered converters
• Single-switch module configuration simplifies gate drive design and reduces auxiliary circuitry compared to half-bridge or full-bridge modules
• Isolated copper baseplate construction enables direct mounting to standard heatsink profiles with low thermal resistance junction-to-case
• Fuji low-saturation IGBT technology provides controlled VCE(sat) for reduced conduction losses across the operating current range
• Integrated freewheeling diode co-packaged with the IGBT switch for complete chopper or inverter leg implementation
• Industry-standard module footprint and terminal layout compatible with common Fuji 1MBH-series gate driver and mounting hardware

With a factory lead time of 99 weeks for new production, the 1MBH25D-120 presents a significant procurement challenge for maintenance teams managing unplanned equipment downtime or engineering teams in active production. Fuji IGBT modules of this generation are increasingly difficult to source through standard distribution channels, making authorized stocking distributors critical to keeping legacy drives and inverters operational. ATI Accurate Technology maintains ready inventory of hard-to-find and long-lead-time Fuji IGBT modules specifically to close this supply gap for industrial MRO and OEM customers who cannot afford a two-year wait for a critical switching device.
