Infineon IKW40N120H3FKSA1: A High-Performance 1200V TRENCHSTOP™ IGBT7 for Industrial Drives and UPS Applications

The evolution of power electronics demands semiconductor devices that deliver higher efficiency, greater power density, and enhanced reliability. Addressing these needs, Infineon Technologies introduces the IKW40N120H3FKSA1, a 1200V IGBT7 housed in a TO-247 package that sets a new benchmark for performance in industrial drive and uninterruptible power supply (UPS) systems.

As part of the advanced TRENCHSTOP™ IGBT7 family, this device leverages Infineon’s latest micro-pattern trench technology. This innovation significantly reduces both static and dynamic losses, enabling higher switching frequencies and lower thermal dissipation compared to previous generations. The result is a substantial improvement in overall system efficiency, which is critical for reducing energy consumption and operating costs in high-power applications.

A key feature of the IKW40N120H3FKSA1 is its optimized trade-off between switching losses and saturation voltage (Vce(sat)). The IGBT7 technology achieves an exceptionally low Vce(sat), which minimizes conduction losses during operation. This is particularly beneficial in circuits like three-phase inverters for motor drives, where lower losses translate to cooler operation and reduced stress on cooling systems. Furthermore, the device offers robust short-circuit capability (up to 3µs), ensuring system safety and durability under fault conditions.

The device is also co-packed with a robust NTC thermistor, integrated directly into the package. This allows for precise real-time temperature monitoring at the chip level, enabling smarter and more responsive thermal management. System controllers can use this data to proactively adjust operation, prevent overheating, and enhance the reliability and lifespan of the entire application.

The combination of high efficiency, power density, and integrated temperature sensing makes the IKW40N120H3FKSA1 an ideal solution for a wide range of demanding applications. It is perfectly suited for:

Industrial Drives: AC motor drives, servo drives, and pumps.

Uninterruptible Power Supplies (UPS): Both three-phase and high-performance single-phase online UPS systems.

Solar Inverters and other renewable energy conversion systems.

Welding Equipment and industrial SMPS.

ICGOODFIND: The Infineon IKW40N120H3FKSA1 represents a significant leap forward in power semiconductor technology. By masterfully balancing low losses, high robustness, and integrated monitoring, it empowers designers to create more compact, efficient, and reliable next-generation power electronics for industrial and UPS markets.
