High-Performance Design with the Infineon IPP65R110CFD 650V CoolMOS™ CFD2 Power Transistor

Modern power electronics demand transistors that combine high efficiency, thermal performance, and system-level reliability. The Infineon IPP65R110CFD, a 650V CoolMOS™ CFD2 power transistor, stands out as a top-tier component engineered to meet these rigorous requirements in applications such as server and telecom power supplies, industrial motor drives, and renewable energy systems.

A key highlight of the IPP65R110CFD is its exceptionally low on-state resistance (RDS(on)) of just 110 mΩ, significantly reducing conduction losses. This allows designers to achieve higher power density and improved energy efficiency, especially in high-frequency switching topologies like totem-pole PFC (Power Factor Correction) and LLC resonant converters. The reduced power dissipation not only enhances performance but also minimizes the need for complex cooling mechanisms.

Another defining feature is the integrated fast body diode, which offers superior reverse recovery characteristics. This results in reduced switching losses and lower electromagnetic interference (EMI), making the device ideal for hard- and soft-switching applications. The diode’s ruggedness also improves reliability in circuits prone to high dv/dt and di/dt stress.

The CoolMOS™ CFD2 technology further incorporates advanced charge compensation principles, enabling a smaller die size without compromising breakdown voltage or switching speed. This structural innovation contributes to lower gate charge (Qg) and output capacitance (Coss), allowing for faster switching frequencies and smoother operation.

Thermal management is also a critical strength. The transistor’s low thermal resistance and high peak current capability ensure stable performance under demanding conditions. Designers can leverage these traits to build more compact and robust systems with extended operational lifespans.

In summary, the Infineon IPP65R110CFD sets a high standard in power semiconductor design, offering a blend of low losses, high switching speed, and excellent thermal behavior.
