Infineon AUIRFS3004-7P High-Performance Automotive MOSFET for Advanced Power Switching Applications

The relentless drive towards vehicle electrification, advanced driver-assistance systems (ADAS), and sophisticated onboard features demands robust and highly efficient electronic components. At the heart of these power-hungry systems are MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors), which act as critical switches. The Infineon AUIRFS3004-7P stands out as a premier solution engineered specifically to meet the rigorous demands of the modern automotive landscape.

This MOSFET is built upon Infineon's advanced OptiMOS™ technology, a hallmark of performance and reliability. Designed in a compact and robust D2PAK 7-pin package, it offers an optimal balance between superior electrical performance and efficient thermal management. The key to its success lies in its exceptionally low typical on-state resistance (RDS(on)) of just 1.8 mΩ. This ultra-low resistance is crucial as it directly translates to minimized conduction losses. In practical terms, this means the MOSFET generates less heat during operation, leading to higher overall system efficiency and reduced cooling requirements.

Furthermore, the AUIRFS3004-7P is characterized by its low gate charge (Qg), which enables fast switching speeds. This is particularly vital for high-frequency switching applications like DC-DC converters and motor control systems, where switching losses can significantly impact performance. The combination of low RDS(on) and low Qg ensures that the device operates efficiently across a wide range of frequencies and load conditions.

As a true automotive-grade component, it complies with the AEC-Q101 qualification standard, guaranteeing its reliability and performance under the extreme conditions inherent to automotive environments. This includes exceptional resilience against high temperatures, thermal cycling, and mechanical stress. Its design also incorporates a high avalanche ruggedness, providing enhanced protection against voltage spikes and inductive load switching events that are common in automotive electrical systems.

Typical applications where the AUIRFS3004-7P excels include:

Electric Power Steering (EPS) systems

Brushed and Brushless DC Motor Drives

Solid-State Relays and Solenoid Control

Advanced Battery Management Systems (BMS)

DC-DC Converters in 12/48V systems
