Infineon FZ3600R17HE4: High-Performance 3 kV IGBT Module for Industrial Drives and Traction Applications

The demand for robust and efficient high-power conversion continues to grow across heavy industries and global transportation networks. Addressing this need, Infineon Technologies has developed the FZ3600R17HE4, a state-of-the-art IGBT module engineered to set new benchmarks in performance and reliability for demanding medium-voltage applications.

This module is built upon a 3.3 kV IGBT4 chipset, a proven technology known for its low saturation voltage (Vce(sat)) and exceptionally low switching losses. This combination is crucial for achieving high operational efficiency, which directly translates into reduced system energy consumption and lower operating costs over the lifetime of the equipment. With a high nominal current rating of 3600 A, the FZ3600R17HE4 is capable of handling the substantial power levels required by large industrial motor drives and traction inverters for mainline locomotives and heavy rail.

A key feature of this module is its robust and low-induance package design. The optimized internal layout minimizes parasitic inductance, which is critical for controlling voltage overshoot during the fast switching events inherent in modern PWM inverters. This not only enhances the overall system reliability but also allows for smoother operation and reduced electromagnetic interference (EMI). Furthermore, the module offers multiple parallel connection points, simplifying integration into high-current systems and improving current sharing among devices.

The industry-standard EconoDUAL™ 3 package ensures mechanical compatibility with existing systems and cooling infrastructures, facilitating both new designs and upgrades to existing platforms. The baseplate is designed for low thermal resistance, enabling effective heat dissipation through forced air or liquid cooling systems. This is vital for maintaining junction temperatures within safe operating limits, even under the strenuous, continuous load cycles typical of traction applications.

Target applications are extensive and include:

High-power industrial drives for pumps, compressors, and fans in mining, metal processing, and energy generation.

Traction inverters for mainline and heavy rail locomotives, metros, and trams.

Static VAR Generators (SVGs) and other flexible AC transmission system (FACTS) devices for grid stabilization.

ICGOODFIND: The Infineon FZ3600R17HE4 stands out as a premier 3.3 kV IGBT solution, delivering an optimal balance of high current capability, low losses, and superior ruggedness. Its design is meticulously tailored to meet the stringent requirements of industrial and traction applications, promising enhanced efficiency and unwavering reliability in the most challenging environments.
