The Fuji 1MBH15D-120 is a single-configuration Insulated Gate Bipolar Transistor (IGBT) module rated for 15A continuous collector current and 1200V collector-emitter voltage. Built to Fuji Electric's established power module standards, it delivers low saturation voltage and fast switching characteristics in a compact, isolated baseplate package. The 1200V voltage class provides the necessary headroom for 690V AC bus applications and other high-voltage industrial environments where transient spikes demand robust blocking capability. This module is a dependable choice for engineers specifying discrete or replacement IGBT solutions in medium-power drive and conversion systems.

The 1MBH15D-120 sees broad use across industrial and commercial power electronics platforms. Typical applications include variable frequency drives (VFDs), servo and spindle amplifiers, uninterruptible power supplies (UPS), solar inverters, and welding power supplies. Its 1200V rating makes it particularly appropriate for systems operating from three-phase 480V or 600V mains where DC bus voltages can reach 800V or higher under regenerative conditions. OEMs and MRO teams maintaining legacy Fuji-based drive platforms will recognize this part number as a direct fit in established bill-of-materials configurations.

Key Features of the 1MBH15D-120:

• 1200V VCES rating provides robust voltage blocking margin for 690V-class AC systems and high-bus-voltage inverter topologies
• 15A continuous collector current suitable for medium-power switching stages in drives and inverter output phases
• Single IGBT configuration simplifies gate drive circuit design and allows flexible placement within custom or modular power stages
• Isolated copper baseplate construction enables direct heatsink mounting and effective thermal management in high-cycle industrial environments
• Low VCE(sat) characteristic reduces conduction losses and thermal dissipation at rated current, improving overall converter efficiency
• Compatible with standard Fuji IGBT gate drive voltage levels (typically +15V / -15V), easing integration into existing drive platforms

With a published factory lead time of 99 weeks, the 1MBH15D-120 is effectively unavailable through standard distribution channels on any reasonable procurement timeline. For OEM production schedules, MRO replacements, or emergency repairs, waiting nearly two years is not a viable option. ATI Accurate Technology maintains independent stock of hard-to-find and long-lead-time IGBT modules precisely for situations like this. Whether you need a single replacement unit or a larger quantity for a production run, ATI can fulfill your order from existing inventory without the extended wait.
