Infineon IRFS4610TRLPBF: High-Performance Power MOSFET for Automotive and Industrial Applications

The relentless drive for higher efficiency, greater power density, and enhanced reliability in electronic systems places immense demands on power switching components. Addressing these challenges head-on, the Infineon IRFS4610TRLPBF stands out as a premier power MOSFET engineered to excel in the most demanding automotive and industrial environments.

This device is built upon Infineon's advanced HEXFET® technology, a hallmark of performance and robustness. With a low on-state resistance (RDS(on)) of just 4.5 mΩ, the IRFS4610TRLPBF minimizes conduction losses, which is paramount for improving overall system efficiency and managing thermal performance. This characteristic is especially critical in applications like electric power steering (EPS), braking systems, and engine management units, where every watt of power saved translates into better fuel economy and cooler operation.

The MOSFET's capability to handle a continuous drain current (ID) of 124A and its 100V drain-to-source voltage (VDS) rating make it an incredibly versatile component. This high current handling capacity ensures it can manage substantial power loads in industrial machinery, such as motor drives, solenoids, and power supplies, without compromising performance or longevity.

A key feature of the IRFS4610TRLPBF is its AEC-Q101 qualification, which certifies its suitability for the harsh conditions of automotive applications. It is designed to withstand significant temperature fluctuations, mechanical stress, and electrical transients, ensuring unwavering reliability where failure is not an option. Furthermore, its low gate charge (QG) facilitates fast switching speeds, which is essential for high-frequency switching regulators that help reduce the size of passive components like inductors and capacitors.

The package itself, a D2PAK (TO-263), offers an excellent balance between compact footprint and superior thermal performance. This allows for efficient heat dissipation directly from the drain tab to the PCB or an external heatsink, maintaining the junction temperature within safe operating limits even under high-stress conditions.

ICGOODFIND Summary: The Infineon IRFS4610TRLPBF is a high-performance power MOSFET that sets a benchmark for efficiency and durability. Its exceptionally low RDS(on), high current capability, and automotive-grade robustness make it an optimal and reliable switching solution for the next generation of automotive and industrial power systems.
