Infineon IPW65R041CFDFKSA1: Redefining High-Voltage Power Conversion with CoolMOS™ CFD7 Technology

The Infineon IPW65R041CFDFKSA1 is a 650V Power MOSFET from the groundbreaking CoolMOS™ CFD7 series, engineered to deliver exceptional efficiency and reliability in high-performance power supply systems. As a part of Infineon’s latest generation of superjunction MOSFETs, this component is specifically designed to address the growing demands of modern applications such as server and telecom power supplies, industrial SMPS, renewable energy systems, and electric vehicle charging infrastructure.

A defining feature of this MOSFET is its integrated fast body diode, which significantly enhances its robustness in hard-switching and inductive load applications. This built-in diode not only reduces switching losses but also improves reverse recovery characteristics, making the device particularly suitable for zero-voltage switching (ZVS) topologies like phase-shift full-bridge or LLC resonant converters. The result is higher system efficiency, reduced electromagnetic interference (EMI), and the ability to operate at higher switching frequencies—all contributing to more compact and lighter power designs.

With an ultra-low on-state resistance (RDS(on)) of just 41 mΩ, the IPW65R041CFDFKSA1 minimizes conduction losses, leading to cooler operation and better overall energy utilization. Its superior switching performance allows designers to push the limits of power density without compromising thermal management. The device also offers enhanced avalanche ruggedness and high dv/dt capability, ensuring long-term durability even under stressful operating conditions.

Packaged in the industry-standard TO-247, this MOSFET provides excellent thermal conductivity and mechanical stability, simplifying PCB layout and heat sink attachment. Furthermore, its optimized gate charge (Qg) ensures quick and efficient turn-on and turn-off transitions, reducing driving losses and enabling the use of smaller gate drivers.

ICGOOODFIND: The Infineon IPW65R041CFDFKSA1 stands out as a top-tier solution for next-generation power electronics, combining low losses, high switching speed, and exceptional diode performance. It enables engineers to achieve new benchmarks in efficiency and power density while maintaining system reliability.
