Infineon IPW65R048CFDA: Redefining High-Voltage Power Conversion Efficiency

The Infineon IPW65R048CFDA is a 650V CoolMOS™ CFD7 power transistor engineered to meet the escalating demands of modern high-efficiency power supply systems. As part of Infineon’s latest generation of superjunction MOSFETs, this device combines ultra-low on-state resistance with exceptional switching performance, making it ideal for applications such as server SMPS, telecom power systems, industrial drives, and renewable energy inverters.

A key feature of the IPW65R048CFDA is its remarkably low RDS(on) of 48 mΩ, which significantly reduces conduction losses. This allows power designers to achieve higher power density and improved thermal management, even in compact form factors. The CFD7 technology also incorporates an integrated fast body diode, which enhances reverse recovery characteristics and minimizes switching losses in hard-switching topologies.

Furthermore, the transistor offers superior electromagnetic compatibility (EMC) and reduced ringing thanks to optimized parasitic capacitances and gate-drain charge (QGD). This results in smoother switching transitions and lower electromagnetic interference (EMI), simplifying filter design and compliance with international standards.

The device is offered in a TO-247 package, ensuring robust mechanical reliability and efficient heat dissipation. Its high voltage rating of 650V provides ample margin for operation in environments with voltage spikes or transients, increasing system longevity and safety.

Designed for sustainability, the IPW65R048CFDA supports energy-efficient operations, contributing to lower carbon footprints in data centers and industrial infrastructures. Its performance characteristics align with global trends toward electrification and energy conservation.
