Infineon IAUC100N04S6N028ATMA1: High-Performance 100V N-Channel MOSFET for Automotive and Industrial Applications

In the demanding arenas of automotive and industrial electronics, power efficiency, thermal stability, and operational reliability are non-negotiable. The Infineon IAUC100N04S6N028ATMA1 stands out as a premier 100V N-Channel MOSFET engineered specifically to meet these rigorous requirements. This device exemplifies the cutting-edge of power semiconductor technology, delivering a combination of ultra-low on-state resistance (RDS(on)) and exceptional switching performance, which are critical for minimizing power losses and enhancing overall system efficiency.

A key highlight of the IAUC100N04S6N028ATMA1 is its remarkably low RDS(on) of just 0.68 mΩ (max) at 10 V. This exceptionally low resistance directly translates to reduced conduction losses, allowing the MOSFET to handle high currents with minimal voltage drop and heat generation. This is particularly vital in applications like electric vehicle (EV) powertrains, 48V boardnet systems, and high-current DC-DC converters, where every watt saved contributes to longer range, better fuel economy, and improved thermal management.

Built upon Infineon's advanced OptiMOS™ technology, this MOSFET is optimized for high-frequency switching operations. The low gate charge (Qg) and figure-of-merit (FOM) ensure fast turn-on and turn-off times, which is essential for modern switch-mode power supplies (SMPS) and motor control circuits to operate at higher frequencies, leading to smaller magnetic components and more compact system designs.

The component’s AEC-Q101 qualification guarantees its robustness for the harsh automotive environment, enduring extreme temperatures, thermal cycling, and demanding operational loads. Furthermore, its low-profile, space-saving SuperSO8 package (PG-TSON-8) offers superior thermal performance and power density, making it an ideal choice for applications where PCB real estate is at a premium.

ICGOOODFIND: The Infineon IAUC100N04S6N028ATMA1 is a top-tier power solution that sets a high standard for performance and reliability in automotive and industrial sectors. Its blend of ultra-low RDS(on), high switching speed, and robust construction makes it an indispensable component for designers aiming to push the boundaries of efficiency and power density in their next-generation systems.
