Infineon AUIRFR4620TRL: A High-Performance Automotive MOSFET for Switching Applications

In the demanding world of automotive electronics, where reliability and efficiency are paramount, the choice of power switching components is critical. The Infineon AUIRFR4620TRL stands out as a premier N-channel MOSFET engineered specifically to meet these rigorous challenges. This device encapsulates advanced semiconductor technology to deliver superior performance in a compact, robust package.

Designed for a broad spectrum of switching applications, the AUIRFR4620TRL is a key enabler in systems such as electronic power steering (EPS), transmission control units (TCUs), and engine management modules. Its core strength lies in its exceptionally low on-state resistance (RDS(on)) of just 2.6 mΩ (max. at VGS = 10 V). This ultra-low resistance is a game-changer, as it directly translates to minimal conduction losses and significantly higher efficiency. By dissipating less power as heat, the MOSFET allows for more compact designs and reduces the burden on thermal management systems.

Beyond its electrical efficiency, the AUIRFR4620TRL is built for the harsh under-the-hood environment. It is AEC-Q101 qualified, ensuring it meets the strict reliability and quality standards required for automotive applications. It offers an impressive operating temperature range, capable of handling the extreme heat found in modern engine compartments. The device also features avalanche ruggedness, meaning it can withstand high-energy pulses and voltage spikes that are common in automotive electrical systems, thereby enhancing the overall durability and longevity of the electronic control unit (ECU).

Housed in an advanced D2PAK (TO-263) package, this MOSFET provides an optimal balance between power handling capability and board space savings. The package is designed for efficient heat dissipation, further supporting high-current operation.
