Infineon AUIRF7316QTR: High-Efficiency Dual N-Channel MOSFET for Automotive Applications
The relentless drive towards enhanced electrification in the automotive industry demands power components that deliver uncompromising performance, reliability, and efficiency. At the heart of many of these advanced systems, from advanced motor drives and solenoid control to robust DC-DC converters, lies the power MOSFET. The Infineon AUIRF7316QTR stands out as a premier solution, engineered specifically to meet the stringent requirements of modern automotive applications.
This component is a dual N-channel MOSFET co-packaged in a space-saving, thermally efficient PQFN 3.3x3.3 package. Its primary design goal is to minimize power losses and maximize switching efficiency, which is critical for improving overall system fuel economy and reducing heat generation in densely packed electronic control units (ECUs). The device is built using Infineon's advanced OptiMOS™ technology, which provides an exceptional low figure-of-merit (RDS(on) QG). This translates to significantly reduced conduction and switching losses, allowing for higher frequency operation and the design of smaller, lighter magnetic components.
Beyond pure performance, the AUIRF7316QTR is crafted for the demanding automotive environment. It boasts AEC-Q101 qualification, ensuring it meets the rigorous standards for stress resistance and reliability required for vehicle use. Its robust design features a low internal gate resistance and is avalanche rugged, providing enhanced durability against voltage transients and inductive switching events commonly encountered in automotive electrical systems. The combination of a small footprint and excellent thermal performance, facilitated by an exposed leadframe pad, simplifies PCB layout and aids in effective heat dissipation, contributing to long-term reliability.
Furthermore, its dual N-channel configuration offers designers greater flexibility and component consolidation, enabling more compact and cost-effective board designs without sacrificing performance. This makes it an ideal choice for a wide array of applications, including:
Electric Power Steering (EPS)
Transmission Control Units (TCU)
Engine Management Systems
Battery Management Systems (BMS)
LED lighting drivers
ICGOOODFIND: The Infineon AUIRF7316QTR is a superior dual N-channel MOSFET that encapsulates the key trends in automotive electronics: high efficiency, miniaturization, and supreme reliability.
