Infineon IKW50N65F5FKSA1 650V 50A TRENCHSTOP™ 5 IGBT: Powering High-Efficiency Systems
The Infineon IKW50N65F5FKSA1 is a state-of-the-art 650V, 50A IGBT belonging to the advanced TRENCHSTOP™ 5 technology family. Engineered for robust performance and high reliability, this IGBT is designed to meet the demanding requirements of modern power electronic applications, including industrial motor drives, uninterruptible power supplies (UPS), solar inverters, and welding equipment.
A key highlight of this device is its optimized trade-off between low saturation voltage and minimal switching losses. The TRENCHSTOP™ 5 technology incorporates a trench gate field-stop structure that significantly enhances conductivity while reducing turn-off losses. This results in higher overall system efficiency, especially at higher switching frequencies, and allows for more compact designs due to reduced cooling requirements.

The IKW50N65F5FKSA1 features a very low VCE(sat) of typically 1.55V at 25°C, which contributes to lower conduction losses and improved thermal performance. It also offers short-circuit ruggedness and a tight parameter distribution, ensuring consistent and reliable operation even under stressful conditions. The device is housed in a TO-247 package, renowned for its excellent thermal characteristics and ability to handle high currents.
Application notes for this IGBT emphasize the importance of proper gate driving and thermal management. Utilizing a negative gate voltage (e.g., -15V) for turn-off is recommended to enhance noise immunity and prevent parasitic turn-on due to Miller capacitance. Effective heatsinking is crucial to maintain the junction temperature within the specified limit of 175°C, thereby maximizing longevity and performance.
ICGOOODFIND Summary: The Infineon IKW50N65F5FKSA1 stands out as a high-performance IGBT that delivers an exceptional balance of efficiency, power density, and robustness, making it an ideal choice for next-generation power conversion systems.
