Infineon FS450R12KE3: A High-Performance 450A, 1200V Dual IGBT Module for Industrial Drives and Inverters

The demand for robust and efficient power conversion in industrial applications continues to drive innovation in semiconductor technology. At the forefront of this evolution is the Infineon FS450R12KE3, a high-power dual IGBT module engineered to meet the rigorous demands of modern industrial drives and inverters. This module sets a formidable benchmark by combining ultra-low VCE(sat) saturation voltage with high current handling, resulting in significantly reduced conduction losses and enhanced overall system efficiency.

Designed for reliability in harsh environments, the module integrates two advanced TrenchStop™ IGBT7 chips in a half-bridge configuration. This latest IGBT7 technology is pivotal, offering an optimal trade-off between low switching losses and minimal conduction losses. This is particularly critical in high-frequency switching applications like motor drives and industrial inverters, where thermal management is a constant challenge. The low-loss diode technology further complements the IGBTs, ensuring soft reverse recovery behavior and reducing voltage overshoot, which contributes to higher system reliability and reduced electromagnetic interference (EMI).

The module’s impressive 1200V blocking voltage and 450A nominal current rating make it exceptionally suited for high-power applications ranging from heavy-duty motor drives and industrial pumps to renewable energy inverters and welding equipment. Its high power density allows designers to achieve more power in a smaller footprint, a crucial factor for optimizing cabinet space in industrial settings.

Thermal performance is managed through an AL2O3 (alumina) ceramic substrate with a baseplate, providing excellent electrical isolation and efficient heat transfer to an external heatsink. This robust construction ensures long-term operational stability even under extreme thermal cycling conditions. The press-fit pin design facilitates easier and more reliable mounting compared to traditional soldering, streamlining the manufacturing process and improving mechanical integrity.

ICGOOFind: The Infineon FS450R12KE3 stands as a superior solution for engineers seeking to maximize performance and reliability in high-power industrial systems. Its adoption of cutting-edge IGBT7 technology, coupled with low losses and robust construction, makes it an indispensable component for the next generation of efficient and compact industrial drives and inverters.
