Product Details

7MBI100N-060 Product Description

The Fuji Electric 7MBI100N-060 is a high-performance Insulated Gate Bipolar Transistor (IGBT) module engineered for demanding industrial drive and inverter architectures. Rated at 100A continuous collector current and 600V blocking voltage, this module occupies a critical position within the power conversion layer of modern automation systems. Its compact 7MBI-series package integrates six IGBT chips with freewheeling diodes in a standard three-phase bridge configuration, enabling direct deployment in variable frequency drives (VFDs), servo amplifiers, uninterruptible power supplies (UPS), and regenerative braking units across manufacturing, energy, and process control environments.

Designed for Contextual Integration within multi-axis drive platforms and distributed control architectures, the 7MBI100N-060 delivers consistent switching performance across a wide operating temperature range. Its low saturation voltage (VCE(sat)) and optimized gate charge characteristics reduce switching losses, improving overall inverter efficiency and thermal management in high-cycle industrial applications. The module's isolated copper base plate and Al₂O₃ ceramic substrate ensure reliable thermal conductivity to heatsink assemblies, supporting continuous operation in ambient temperatures up to 125°C junction temperature.

Every 7MBI100N-060 unit supplied by NANKMOS undergoes pre-shipment functional verification including gate threshold voltage testing, leakage current measurement, and forward voltage drop confirmation, backed by a 12-Month Warranty covering manufacturing defects and parametric failures under normal operating conditions.

The 7MBI100N-060 functions as the core switching element within the power stage of a complete drive system. In a typical servo or VFD architecture, the module interfaces directly with a dedicated IGBT gate driver board — such as the Fuji Electric EXB841 or EXB840 gate driver hybrid IC — which translates PWM command signals from the motion controller into precise gate voltage pulses. The gate driver's desaturation detection and soft-shutdown circuitry protects the 7MBI100N-060 from short-circuit events, a critical safeguard in high-inertia load applications.

At the control layer, the 7MBI100N-060 receives switching commands from a DSP-based or FPGA-based drive controller, such as those found in Fuji Electric FRENIC series inverter control boards or equivalent third-party motion control platforms. The controller generates six-channel complementary PWM signals with programmable dead-time insertion to prevent shoot-through conditions across the module's upper and lower IGBT pairs.

On the DC bus side, the module connects to a pre-charged capacitor bank — typically using Nichicon or EPCOS film capacitors rated at 800V–1000V DC — which smooths rectified mains voltage and provides energy storage for regenerative braking cycles. A DC bus voltage sensor feeds real-time bus voltage data back to the controller, enabling dynamic braking chopper activation through a separate brake IGBT module such as the Fuji Electric 1MBI100N-060 or 2MBI100N-060.

For current sensing and overcurrent protection, Hall-effect current sensors (e.g., LEM LA 100-P or Honeywell CSNS100M) are mounted on the AC output terminals of the 7MBI100N-060, providing isolated current feedback to the drive controller's ADC inputs. This feedback loop enables field-oriented control (FOC) or direct torque control (DTC) algorithms to maintain precise motor torque and speed regulation across the full operating range.

In multi-axis systems, multiple 7MBI100N-060 modules may be deployed in parallel on a shared DC bus architecture, with individual gate driver boards synchronized to a common PWM carrier frequency to minimize circulating currents. Thermal management across the array is achieved through a shared liquid-cooled or forced-air heatsink assembly, with NTC thermistors embedded near each module's base plate providing temperature feedback to the system's thermal protection logic.

At the communication and supervision layer, the drive controller interfaces with a higher-level PLC or DCS via PROFIBUS-DP, EtherCAT, or CANopen fieldbus protocols, enabling coordinated multi-axis motion sequencing, fault logging, and remote parameter adjustment. Complementary components in this architecture include the Fuji Electric FRENIC-MEGA or FRENIC-MULTI inverter control PCBs, resolver-to-digital converter (RDC) modules for encoder feedback processing, and EMC input filters (e.g., Schaffner FN3258 series) installed upstream of the rectifier stage to suppress conducted emissions.

Manufacturing & Packaging Lines: In high-speed packaging and assembly automation, the 7MBI100N-060 drives servo motors controlling conveyor indexing, robotic arm joints, and label applicator axes. Its fast switching frequency capability (up to 15–20 kHz) supports smooth torque ripple suppression in precision positioning applications, reducing mechanical wear on gearboxes and ball screws.

Power Generation & Energy Infrastructure: In wind turbine pitch control and solar inverter systems, the 7MBI100N-060 operates within grid-tied inverter bridges converting DC bus energy to three-phase AC output. Its 600V blocking voltage is well-matched to 400V AC grid-connected systems with standard 650–700V DC bus operating points. Redundant module configurations with bypass contactors ensure continued operation during single-module maintenance events.

Petrochemical & Process Control: Pump and compressor VFDs in oil refinery and chemical plant environments demand continuous-duty IGBT modules capable of sustained 100% load operation across wide ambient temperature ranges. The 7MBI100N-060's robust thermal design and isolated base plate construction support reliable operation in ATEX-adjacent control panel installations where thermal cycling and vibration are persistent stressors.

Water Treatment & Utilities: Municipal water treatment facilities deploy variable-speed pump drives to optimize energy consumption across varying flow demand profiles. The 7MBI100N-060 enables precise pump speed modulation from 10% to 100% of rated speed, reducing water hammer effects and extending pump mechanical life. Its compatibility with standard 7MBI-series gate driver footprints simplifies maintenance part standardization across large pump station fleets.

Mining & Metallurgy: In belt conveyor drives, hoist systems, and rolling mill main drives, the 7MBI100N-060 is deployed in parallel configurations to achieve higher current ratings. Regenerative braking energy from downhill conveyor loads is fed back to the DC bus and redistributed to motoring axes, improving overall system energy efficiency. The module's short-circuit withstand capability (tsc ≥ 10μs) provides critical protection margin during load fault events in these high-consequence applications.

Marine & Shipboard Systems: Shipboard electric propulsion and thruster control systems require IGBT modules with high vibration resistance and wide temperature tolerance. The 7MBI100N-060's screw-terminal construction and isolated base plate mounting provide mechanical robustness suitable for marine-grade drive panel installations, with conformal coating of associated PCBs providing additional humidity protection.

Q1: Is the 7MBI100N-060 directly interchangeable with other 7MBI-series modules such as the 7MBI100SA-060 or 7MBI100U4B-060? The 7MBI100N-060 (N-Series) shares the same 100A/600V electrical ratings and 7MBI package footprint as the SA and U4B sub-series, but differs in internal chip generation, switching characteristics, and gate charge parameters. Direct substitution requires verification of gate drive voltage compatibility (typically +15V/-8V for N-Series vs. +15V/-15V for some SA-Series variants), dead-time settings, and thermal resistance values. NANKMOS recommends consulting the Fuji Electric 7MBI-series application note and confirming gate driver compatibility before substitution in existing drive designs.

Q2: What gate driver circuit is recommended for the 7MBI100N-060 in a 15kHz PWM inverter application, and what protection features should be implemented? Fuji Electric's EXB841 hybrid gate driver IC is the primary recommended driver for the 7MBI100N-060 in medium-frequency inverter applications. It provides +15V turn-on and -8V turn-off gate drive, integrated desaturation (VCE) overcurrent detection with soft-shutdown output, and active Miller clamp functionality. For applications requiring isolated gate drive with enhanced fault reporting, the Concept 2SD315AI or equivalent isolated gate driver with SCALE-2 technology provides additional diagnostic output channels compatible with DSP-based fault logging systems. Dead-time insertion of 2–4μs is recommended at 15kHz to prevent shoot-through under worst-case gate delay conditions.

Q3: What does the 12-Month Warranty cover for the 7MBI100N-060, and what is NANKMOS's inventory and lead-time commitment for this module? The 12-Month Warranty covers manufacturing defects, parametric failures (VCE(sat), ICES, VGE(th) out of datasheet specification), and premature failure under normal operating conditions as defined in the Fuji Electric 7MBI100N-060 datasheet. Warranty claims require return of the failed unit with a completed failure report. Physical damage from overvoltage, incorrect gate drive, improper mounting torque, or thermal interface material omission is excluded. NANKMOS maintains buffer stock of the 7MBI100N-060 to support same-week dispatch for standard order quantities (1–20 units), with pre-shipment functional testing documentation available upon request for OEM and MRO procurement programs.
