Infineon IRF7240TRPBF: A High-Performance Power MOSFET for Efficient Switching Applications
The relentless pursuit of higher efficiency and power density in modern electronics places immense demands on power management components. At the heart of many advanced switching systems, from DC-DC converters and motor controls to power supply units (PSUs), lies the Power MOSFET. The Infineon IRF7240TRPBF stands out as a premier component engineered to meet these challenges, offering a blend of low on-state resistance and high switching speed that is critical for minimizing power losses and enhancing overall system performance.
This MOSFET is constructed using Infineon's advanced proprietary technology, which optimizes the trade-off between conduction losses and switching characteristics. A key specification is its exceptionally low drain-source on-state resistance (RDS(on)) of just 9.5 mΩ (max). This ultra-low resistance directly translates to reduced conduction losses when the device is fully switched on, allowing for higher current handling with minimal voltage drop and significantly lower heat generation. This is paramount for improving efficiency, especially in high-current applications.

Furthermore, the IRF7240TRPBF is designed for high-speed switching operations. Its low gate charge (Qg) and optimized internal capacitances ensure rapid turn-on and turn-off times. This capability is essential for applications operating at high frequencies, such as switch-mode power supplies (SMPS), where faster switching enables the use of smaller passive components like inductors and capacitors, thereby reducing the overall system size and cost.
Housed in a robust D²Pak (TO-263) package, the component offers a high power dissipation capability of 140W, ensuring reliable operation under demanding thermal conditions. The package is designed for efficient heat transfer, making it easier to manage thermal performance on the PCB through appropriate heatsinking. With a voltage rating of 55V and a continuous drain current (ID) of 15A at 100°C, it provides a solid and reliable power handling foundation for a wide range of industrial and commercial applications.
