Infineon IKW75N65ET7: Powering the Next Generation of High-Efficiency Systems

The relentless pursuit of higher efficiency, greater power density, and enhanced reliability in power electronics drives continuous innovation in semiconductor technology. At the forefront of this evolution is the Infineon IKW75N65ET7, a 650V, 75A High-Speed IGBT that sets a new benchmark for performance in demanding applications. As a prime example of the advanced TRENCHSTOP™ 7 technology, this device is engineered to minimize losses and maximize switching efficiency.

A key strength of the IKW75N65ET7 lies in its optimized trade-off between switching losses and saturation voltage (Vce(sat)). The advanced trench gate field-stop structure enables significantly lower conduction losses compared to previous generations. This is crucial for applications operating at high frequencies, where every watt saved translates into cooler operation, smaller heatsinks, and higher overall system efficiency. Furthermore, its high-speed switching capability allows for the design of compact and lightweight power supplies and inverters without compromising on performance.

The device is also designed for robustness and ease of use. It features a very tight parameter distribution and a positive temperature coefficient, which simplifies the paralleling of multiple IGBTs for higher current requirements. The robust short-circuit capability (SCSOA) ensures operational safety in harsh conditions, making it a dependable choice for industrial environments. The anti-parallel emitter-controlled HEXTOOL™ diode further enhances the overall switching performance and reliability of the module.

Typical applications that benefit from the superior performance of the IKW75N65ET7 include:

Industrial Motor Drives and Controls

Uninterruptible Power Supplies (UPS)

Solar Inverters and Renewable Energy Systems

Welding Equipment

High-Frequency Switching Power Supplies (SMPS)
