Infineon IPW50R140CP: 50A, 140mΩ OptiMOS 5 Power MOSFET for High-Efficiency Power Conversion

The relentless pursuit of higher efficiency and power density in modern electronic systems places immense demands on power switching components. Addressing this challenge, the Infineon IPW50R140CP stands out as a premier OptiMOS™ 5 Power MOSFET engineered to set new benchmarks in performance. This device is specifically designed for demanding applications, including switch-mode power supplies (SMPS), motor control, and solar inverters, where every milliohm and every milliamp counts.

At the heart of this MOSFET's superior performance is its exceptionally low on-state resistance (RDS(on)) of just 140mΩ at a 10V gate drive. This ultra-low resistance is a key factor in minimizing conduction losses, which directly translates to higher efficiency and reduced heat generation. The part is rated for a continuous drain current (ID) of 50A at 25°C, showcasing its ability to handle high power levels with robustness and reliability.

A defining feature of the OptiMOS™ 5 technology is its optimized switching performance. The IPW50R140CP achieves an outstanding balance between low gate charge (Qg) and low RDS(on). This combination ensures not only minimal switching losses but also allows for higher switching frequencies. Designers can leverage this to reduce the size and cost of magnetic components (inductors and transformers), leading to more compact and lightweight power solutions.

Housed in a TO-247 package, the component offers excellent thermal characteristics, facilitating efficient heat dissipation away from the silicon die. This mechanical robustness is crucial for maintaining performance and longevity in high-stress environments. Furthermore, the device boasts a high avalanche ruggedness, providing an additional layer of protection against voltage spikes and unpredictable transient events in real-world applications.

ICGOODFIND: The Infineon IPW50R140CP is a top-tier power MOSFET that exemplifies the advancements of OptiMOS™ 5 technology. Its best-in-class combination of low RDS(on), high current handling, and fast switching characteristics makes it an indispensable component for engineers aiming to push the boundaries of efficiency and power density in their next-generation designs.
