Infineon AUIRF2804STRL7P: High-Performance Automotive MOSFET for Demanding Switching Applications
The relentless drive towards greater efficiency, power density, and reliability in automotive electronics places immense demands on core components like power switches. Addressing these challenges head-on, the Infineon AUIRF2804STRL7P stands out as a premier N-channel power MOSFET engineered specifically for the rigorous environment of modern vehicles. This device is a cornerstone for designers developing robust and efficient switching applications, from engine management and transmission control to advanced lighting systems and DC-DC converters.
A key strength of the AUIRF2804STRL7P lies in its exceptionally low on-state resistance (RDS(on)) of just 1.6 mΩ. This ultra-low resistance is critical for minimizing conduction losses during operation. When a MOSFET is in its on-state, power is dissipated as heat proportional to its RDS(on) and the square of the current (I²R). By achieving such a low figure, this MOSFET significantly enhances overall system efficiency, reduces thermal stress, and allows for higher current handling in a compact form factor, making it ideal for space-constrained automotive modules.
Beyond raw performance, the device is specifically qualified for the harsh automotive environment. It complies with the stringent AEC-Q101 standard, ensuring it meets the rigorous quality and reliability requirements for automotive-grade components. This includes superior resilience against temperature fluctuations, mechanical stress, and operational extremes. Furthermore, its 100% avalanche tested qualification guarantees robustness against unexpected voltage spikes and inductive switching events that are commonplace in automotive electrical systems, thereby significantly enhancing system longevity and failure prevention.
The AUIRF2804STRL7P is housed in a Super SO8 package (D2PAK), which offers an excellent balance between compact size and superior thermal performance. This package is designed to efficiently transfer heat from the silicon die to the PCB, enabling higher power dissipation and more reliable operation under continuous load. The package also features an optional separated source tab, which provides designers with greater flexibility in PCB layout to optimize switching performance and reduce parasitic inductance in high-frequency circuits.
In application, this MOSFET excels in demanding switching scenarios such as in anti-lock braking systems (ABS), electronic power steering (EPS), and fuel injector drivers. Its fast switching speeds and high robustness ensure precise control and reliable operation of these critical vehicle functions, directly contributing to both vehicle performance and passenger safety.

ICGOOODFIND: The Infineon AUIRF2804STRL7P is a top-tier automotive MOSFET that masterfully combines ultra-low conduction losses, superior robustness, and proven reliability. Its AEC-Q101 qualification and avalanche ruggedness make it an indispensable component for engineers designing high-efficiency, high-reliability power switching systems in the demanding automotive sector.
