The Fuji 7MBR50UA120-50 is a 1200V, 50A IGBT power module from Fuji Electric's 7MBR UA-series, engineered for high-frequency switching in variable-speed drives, inverters, and industrial power conversion systems. The module integrates IGBT switches with fast-recovery freewheeling diodes in a compact, isolated base package. Its low saturation voltage (V_CE(sat)) and optimized gate charge characteristics minimize conduction and switching losses, making it well suited for systems where thermal management and energy efficiency are primary design concerns. New OEM units are available now at ATI Accurate Technology with same-day shipping capability.

The 7MBR50UA120-50 is widely used in AC motor drives, servo amplifiers, UPS systems, induction heating equipment, and general-purpose inverter platforms operating from 3-phase line voltages up to 690V AC. Its rugged construction supports the continuous duty cycles found in CNC machinery, HVAC compressor drives, and conveyor systems. Maintenance engineers retrofitting older drive systems frequently specify this module as a direct replacement, and OEM equipment manufacturers rely on it for new production builds where proven switching performance and established gate driver compatibility are essential.

Key Features of the 7MBR50UA120-50:

• 1200V V_CES rating provides robust voltage blocking margin for 480V–690V AC bus applications
• 50A continuous collector current with low V_CE(sat) for reduced conduction losses at rated load
• Integrated fast-recovery anti-parallel freewheeling diodes optimized for hard-switching inverter topologies
• Isolated copper base plate for direct heatsink mounting and simplified thermal interface design
• UA-series package pinout maintains compatibility with existing Fuji gate driver and PCB layouts
• Designed for switching frequencies suitable for PWM motor drive and resonant converter applications

With a factory lead time of 99 weeks on new production orders, the 7MBR50UA120-50 is a chronically long-lead-time component that can stall repair timelines and halt new equipment builds. Production lines and service organizations that depend on Fuji IGBT modules cannot afford to wait nearly two years for factory fulfillment. ATI Accurate Technology maintains independent stock of hard-to-find and long-lead-time power semiconductors precisely to bridge this gap. Whether you need a single module for an emergency repair or a scheduled quantity for production continuity, ATI's inventory is available now without factory queue delays.
