The 7MBR15SA140-50-FUJI is a 7-pack IGBT module rated for 15A continuous collector current and a 1400V collector-emitter voltage, built to the Fuji Electric SA-series platform specification. The 7-in-1 configuration integrates six inverter IGBTs plus a brake chopper transistor into a single isolated baseplate package, simplifying PCB layout and thermal management in compact drive designs. With low saturation voltage (V_CE(sat)) and fast switching characteristics, this module delivers high efficiency and reduced switching losses across the full operating range — a critical requirement in variable-speed drive and servo amplifier topologies.

This module is widely deployed in industrial variable-frequency drives (VFDs), servo amplifiers, CNC spindle inverters, elevator traction drives, and uninterruptible power supply (UPS) systems where a high blocking voltage of 1400V provides the necessary safety margin for 690V AC bus applications. The integrated brake chopper IGBT makes it a natural fit for regenerative braking circuits in crane and hoist controls, conveyors, and HVAC compressor drives. OEM machine builders and MRO teams standardized on Fuji SA-series modules will find the 7MBR15SA140-50-FUJI a direct form, fit, and function solution.

Key Features of the 7MBR15SA140-50-FUJI:

• 1400V V_CES rating provides robust voltage margin for 690V AC three-phase input bus applications
• 15A continuous collector current with a 7-in-1 topology (6 inverter IGBTs + 1 brake chopper) in a single isolated module package
• Low V_CE(sat) and optimized gate charge characteristics reduce conduction and switching losses at typical drive switching frequencies (2–16 kHz)
• Isolated copper baseplate construction enables direct heatsink mounting with controlled thermal resistance, simplifying thermal stack design
• Integrated freewheeling diodes on all IGBT positions eliminate external diode components and reduce parasitic inductance in the commutation loop
• Compatible with standard Fuji SA-series gate drive circuits and pinout, enabling direct drop-in replacement on existing drive platforms

Fuji SA-series IGBT modules at 1400V have reached end-of-life status with many authorized distribution channels, creating extended lead times that can stretch to 26–52 weeks through standard supply chains. For maintenance engineers managing installed bases of older Fuji-based VFDs and servo drives, unplanned downtime waiting on allocation is not acceptable. ATI Accurate Technology maintains strategic inventory of hard-to-find and obsolete power semiconductor modules precisely to close this gap, providing verified new OEM parts when and where the market cannot.
