Infineon FZ1200R16KF4 | Robust 1600V High-Power IGBT for Demanding Applications
The Infineon FZ1200R16KF4 is an industry-proven high-power IGBT module engineered for reliability and efficiency in the most demanding power conversion systems. With a formidable 1600V collector-emitter voltage and a 1200A continuous collector current rating, this module provides the robust performance required for high-power industrial drives, renewable energy inverters, and large-scale uninterruptible power supplies (UPS). Its design focuses on minimizing losses, maximizing thermal performance, and ensuring long-term operational stability.
Technical Deep Dive: Core Engineering Advantages
The performance of the FZ1200R16KF4 is rooted in Infineon's advanced semiconductor technologies. Two key features establish its technical superiority in high-power environments:
- Trench Field-Stop IGBT3 Technology: This mature and highly reliable technology is central to the module's performance. The trench gate structure increases cell density, which significantly reduces the on-state voltage drop (VCE(sat)). The addition of a field-stop layer allows for a thinner drift region, which not only further lowers VCE(sat) but also curtails the tail current during turn-off, leading to lower switching losses. For system designers, this translates directly into reduced conduction losses and improved overall inverter efficiency.
- Integrated NTC Thermistor: Effective Thermal Management is critical in high-current modules. The FZ1200R16KF4 includes an integrated NTC thermistor, providing a direct and reliable method for monitoring the module's internal temperature. This enables precise thermal protection, preventing catastrophic failures due to overheating and allowing for optimized system performance under varying load conditions.

Application Focus: Where the FZ1200R16KF4 Excels
The robust electrical and thermal characteristics of the Infineon FZ1200R16KF4 make it an ideal choice for several high-power applications:
- Wind Turbine Inverters: The module's high blocking voltage of 1600V provides a significant safety margin for grid-tied inverters, while its high current handling capability is perfect for multi-megawatt wind energy systems. Its low losses contribute to maximizing the energy harvested from the turbine.
- High-Power Industrial Motor Drives: In applications such as large pumps, compressors, and traction drives, the FZ1200R16KF4 delivers the power and reliability needed for precise motor control. Its ability to handle repetitive peak currents ensures stable operation even under demanding start-up and load-change scenarios.
- Uninterruptible Power Supplies (UPS): Data centers and critical industrial facilities rely on large UPS systems for uninterrupted power. The efficiency and proven reliability of these IGBT modules are essential for designing systems that offer maximum uptime with minimal energy waste.

Frequently Asked Questions (FAQ)
1. What are the key considerations for paralleling FZ1200R16KF4 modules?
When paralleling high-current modules, ensuring symmetrical current sharing is vital. This requires careful attention to the physical layout of the busbars to minimize and balance stray inductances. It is also important to match modules with similar V_CE(sat) and V_GE(th) characteristics. The positive temperature coefficient of V_CE(sat) in the FZ1200R16KF4 provides a degree of self-balancing, but a well-designed gate drive circuit and symmetrical layout remain critical for reliable operation.
2. How does the IHM-B package facilitate thermal design?
The IHM-B (IHM-130) package features a large, flat copper baseplate designed for direct mounting onto a heatsink. This provides a low thermal resistance path (Rth(c-h)) for efficient heat dissipation. To maximize performance, it is crucial to use a high-quality thermal interface material (TIM) and ensure proper mounting torque to achieve uniform pressure and minimize air gaps. The module's isolated case simplifies the thermal design by not requiring an additional insulating layer between the module and a grounded heatsink.
