Infineon AUIRF7313QTR: High-Performance Dual N-Channel MOSFET for Automotive Applications

The relentless drive towards greater efficiency, reliability, and power density in automotive electronics demands components that are engineered to excel under the most demanding conditions. The Infineon AUIRF7313QTR stands out as a premier solution, a dual N-channel MOSFET specifically designed to meet the rigorous standards of the automotive industry. This device integrates two high-performance MOSFETs in a single, space-saving package, offering engineers a powerful tool for a wide range of applications.

Engineered for robustness, the AUIRF7313QTR is AEC-Q101 qualified, ensuring it meets the stringent quality and reliability requirements for automotive components. It is built using Infineon's advanced OptiMOS™ technology, which is renowned for achieving an exceptional balance between low on-state resistance (R DS(on)) and low gate charge (Q G). This technological advantage translates directly into superior switching performance and significantly reduced power losses, which is critical for improving overall system efficiency and managing thermal loads.

The device features a very low typical R DS(on) of just 2.3 mΩ at 10 V, enabling it to handle high currents with minimal voltage drop and conduction losses. This makes it an ideal choice for high-current switching tasks. Its compact PQFN 3.3x3.3mm package offers excellent thermal performance due to an exposed die attach pad, allowing for efficient heat dissipation from the dual MOSFETs into the PCB. This is vital for maintaining performance and reliability in the high-temperature environments found under the hood.

Key automotive applications for the AUIRF7313QTR include:

BLDC motor control for pumps, fans, and window lift systems.

Solid-State Relays (SSRs) and high-current load switches.

DC-DC converters in infotainment and advanced driver-assistance systems (ADAS).

Battery management systems (BMS) and reverse polarity protection circuits.

ICGOOODFIND: The Infineon AUIRF7313QTR is a top-tier dual N-channel MOSFET that delivers outstanding efficiency, power density, and reliability for demanding automotive applications. Its exceptional low R DS(on), compact thermally-enhanced package, and AEC-Q101 qualification make it an optimal choice for designers focused on creating robust and high-performance electronic systems for modern vehicles.
