FUJI 2MBI300N-060 – Dual-Pack IGBT Power Module | N-Series 600V Platform
Engineering Background
The FUJI 2MBI300N-060 belongs to FUJI Electric’s N-Series (2MBI) dual-pack IGBT family, engineered for high-current industrial power conversion. Rated at 300 A collector current and 600 V blocking voltage, this module targets medium-voltage drive topologies where switching losses, thermal cycling endurance, and gate-drive simplicity are primary design constraints. The N-Series platform introduced optimized NPT (Non-Punch-Through) cell geometry, delivering a balanced trade-off between conduction loss and turn-off energy that remains competitive in legacy and retrofit drive designs.
Product Positioning
The 2MBI300N-060 is the preferred choice for procurement engineers sourcing replacement or new-build IGBT modules for 37–75 kW AC motor drives, UPS systems, and industrial welding inverters. Its dual-pack (2-in-1) topology reduces bus-bar complexity and simplifies thermal management compared to discrete IGBT assemblies. Konmask.com supplies verified OEM units with full traceability, supporting both MRO replacement and volume OEM procurement.

Proven Application Environments
- AC Variable Frequency Drives (VFD): 37–75 kW three-phase inverter bridges; direct replacement in FUJI FRENIC, Yaskawa G7/F7, ABB ACS series drives using equivalent 300 A / 600 V dual-pack slots.
- Industrial UPS Systems: Online double-conversion UPS rectifier and inverter stages requiring high surge current tolerance and low VCE(sat).
- Welding Inverters: IGBT-based MIG/MAG and plasma cutting power supplies operating at 10–20 kHz switching frequency.
- Servo Drive DC Bus Choppers: Braking chopper circuits in servo amplifiers and regenerative drive systems.
- Induction Heating: Resonant inverter topologies in industrial induction heating equipment.
- Traction Auxiliary Converters: Auxiliary power supply modules in rail and heavy-vehicle electrification systems.
Engineering Advantages
- NPT Cell Technology: Non-Punch-Through IGBT cell structure provides positive temperature coefficient of VCE(sat), enabling reliable parallel operation and natural current sharing without external balancing resistors.
- Integrated Fast-Recovery Freewheeling Diodes: Co-packaged FWDs are optimized for soft recovery, minimizing reverse-recovery-induced voltage spikes and reducing EMI filter requirements.
- Low Thermal Resistance: Rth(j-c) ≤ 0.10 °C/W per switch allows sustained 300 A operation with standard forced-air or liquid-cooled heatsinks without derating.
- Screw-Terminal Robustness: Heavy-duty screw terminals rated for 300 A continuous current withstand vibration and thermal cycling in industrial environments without contact degradation.
- Drop-In Compatibility: Footprint and pinout are interchangeable with FUJI 2MBI300N-060-01 and functionally equivalent to Mitsubishi CM300DY-24NF, Semikron SKM300GB066D, and Infineon FF300R06KE3 in most drive topologies.
- Proven Field Reliability: N-Series modules have accumulated >10 years of field deployment in industrial drives globally, with well-documented gate-drive reference designs (VGE = +15 V / −8 V recommended).
System Architecture & Signal Flow
The 2MBI300N-060 implements a dual-pack (half-bridge) topology: two IGBT switches (Q1 upper, Q2 lower) with anti-parallel freewheeling diodes are integrated in a single module. In a three-phase inverter, three such modules form a complete six-switch bridge. Signal flow for a standard VFD application:
- DC Bus Input: Rectified DC (typically 510–650 VDC for 380 VAC input) applied across P (+) and N (−) terminals.
- Gate Drive: Isolated gate driver (e.g., CONCEPT 2SD315A or equivalent) applies +15 V / −8 V gate signals to G1/E1 and G2/E2 with dead-time ≥ 2 µs.
- PWM Switching: IGBT switches at carrier frequency (typically 2–16 kHz) to synthesize sinusoidal output voltage at U terminal.
- Freewheeling: During dead-time and inductive load freewheeling, integrated FWDs conduct, clamping VCE and protecting IGBTs from overvoltage.
- Thermal Path: Junction → case → heatsink (via thermal interface material, λ ≥ 3 W/m·K recommended) → ambient.

Technical FAQ
Q: What is the difference between 2MBI300N-060 and 2MBI300N-060-01?
A: The -01 suffix denotes a minor process revision with marginally improved VCE(sat) and Eoff characteristics. Both are pin-compatible and electrically interchangeable in most applications. Confirm with your drive OEM if the revision matters for your specific firmware-calibrated drive.
Q: Can the 2MBI300N-060 replace a Mitsubishi CM300DY-24NF?
A: Yes, in most 600 V / 300 A dual-pack slots. Key differences: FUJI uses a slightly different package outline and terminal pitch. Verify mechanical fit and gate-drive voltage compatibility (both use +15 V / −8 V or −15 V). Electrical parameters are functionally equivalent.
Q: What gate resistor value is recommended?
A: FUJI recommends Rg(on) = 2.2–10 Ω and Rg(off) = 2.2–10 Ω depending on switching frequency and EMI requirements. Refer to FUJI application note for the N-Series gate drive design guide.
Q: What thermal interface material should I use?
A: Use a silicone-based TIM with thermal conductivity ≥ 3 W/m·K (e.g., Bergquist GP3000 or equivalent). Apply a uniform thin layer (50–100 µm) and torque mounting screws to 2 N·m in a cross pattern.
Q: Is this module suitable for 690 V AC input systems?
A: No. The 600 V VCES rating is insufficient for 690 V AC (DC bus ≈ 970 V). Use the FUJI 2MBI300N-120 (1200 V) for 690 V AC applications.
Q: Do you provide test reports?
A: Yes. Konmask.com provides incoming inspection reports upon request. Full factory test reports from FUJI are available for OEM customers with NDA agreements.
