Infineon SPW47N60CFD: A High-Performance 600V CoolMOS™ CFD2 Power Transistor

The relentless pursuit of higher efficiency and power density in modern electronics places immense demands on power switching components. Addressing this need, the Infineon SPW47N60CFD stands out as a premier 600V superjunction MOSFET, leveraging the advanced CoolMOS™ CFD2 technology to set a new benchmark in performance for applications like switched-mode power supplies (SMPS), industrial motor drives, and power factor correction (PFC).

At the heart of this transistor's superiority is its revolutionary Charge Compensation Principle, which is the foundation of the CoolMOS™ family. This technology enables an exceptionally low on-state resistance (R DS(on)) of just 47mΩ maximum, drastically reducing conduction losses. The result is cooler operation and significantly higher overall efficiency, even when handling high currents. This characteristic is paramount for designers aiming to minimize heat sink size and boost the power density of their systems.

Beyond low conduction losses, the CFD2 (Fast Diode 2) variant introduces critical enhancements for hard-switching and bridge topology applications. It features an intrinsically fast body diode with superior reverse recovery characteristics. The softness and speed of this diode drastically reduce switching losses and minimize electromagnetic interference (EMI), a common challenge in high-frequency circuits. This allows for higher switching frequencies, enabling the use of smaller passive components like inductors and transformers.

Furthermore, the SPW47N60CFD is engineered for robust and reliable operation. It offers an excellent avalanche ruggedness and is qualified according to the highest quality standards, including JEDEC. Its low gate charge (Q G) ensures easy drive capability, simplifying gate driver design. The combination of low switching losses, low R DS(on), and a strong body diode makes this device an exceptionally versatile and reliable choice for demanding environments, from server farms to factory automation.
