Technical Specifications

Key Functional Features

• Ultra-High Power Handling Capacity

  Delivers a 4500 V blocking voltage and 4000 A continuous current rating, enabling it to manage extreme power loads in high-voltage industrial systems. It handles high surge currents without degradation, making it ideal for heavy-duty power conversion.
• Snubberless High-Speed Switching

  Features an advanced gate-commutated design with exceptional high dv/dt and di/dt tolerance. It achieves full, reliable turn-off in ~1 µs without requiring external snubber circuits, simplifying system design, reducing component count, and lowering failure points.
• Low Power Loss & High Efficiency

• Robust Press-Pack Construction

  Utilizes a press-pack (hockey-puck) metal package with no internal solder joints. This design provides exceptional resistance to mechanical vibration, thermal fatigue, and thermal cycling, ensuring long-term stability in high-stress environments.
• Advanced Dual-Sided Water Cooling

  Incorporates a dual-sided direct water-cooling system for efficient heat dissipation. This design maintains optimal thermal performance even under continuous full-load operation, supporting high power density and extended operational life.
• Integrated Gate Drive & Status Monitoring

  Features a fully integrated gate drive circuit with a simplified control interface and real-time status feedback. It includes built-in over-current, over-voltage, and over-temperature protection, enhancing system safety and enabling precise condition monitoring.
• High Electromagnetic Immunity

  Engineered with superior electromagnetic interference (EMI) and radio frequency interference (RFI) resistance. It maintains stable switching performance in electrically noisy industrial environments, ensuring consistent operation without signal interference.
• Excellent Parameter Consistency

  Manufactured with strict quality controls, ensuring high uniformity of electrical parameters across modules. This allows for direct parallel operation with precise current sharing, facilitating easy system scaling to higher power levels.
• Wide Temperature & Harsh Environment Tolerance

  Operates reliably across an extended temperature range (-40 °C to +125 °C) and resists damage from industrial contaminants, humidity, and mechanical shock, suitable for the most demanding industrial settings.
