Infineon IRF100S201: High-Performance Automotive MOSFET for Switching Applications
The relentless drive towards vehicle electrification demands power components that deliver uncompromising performance, reliability, and efficiency. At the heart of many modern automotive systems, from engine management and braking to advanced lighting and DC-DC converters, lies the power MOSFET. The Infineon IRF100S201 stands out as a premier component engineered specifically to meet the rigorous demands of these high-frequency switching applications.
This MOSFET is built upon Infineon's advanced automotive-grade OptiMOS™ technology. This platform is renowned for its exceptional balance of low on-state resistance (RDS(on)) and superior switching performance. The IRF100S201, a N-channel MOSFET, boasts an ultra-low maximum RDS(on) of just 1.3 mΩ at a gate voltage of 10 V. This remarkably low resistance is a key figure of merit, as it directly translates to minimized conduction losses. In practical terms, this means the device dissipates less power as heat during operation, leading to cooler running systems, higher overall efficiency, and the potential for reduced cooling requirements.

Beyond its static performance, the device excels in dynamic operation. It features low gate charge (Qg) and excellent figure-of-merit (FOM) characteristics, which are critical for high-frequency switching. These attributes ensure fast switching transitions, reducing switching losses and enabling designers to push the frequencies of their power converters higher. This allows for the use of smaller passive components like inductors and capacitors, saving valuable space and weight—a constant priority in automotive design.
As an AEC-Q101 qualified component, the IRF100S201 is guaranteed to withstand the harsh environment under the hood. It is designed for high operational reliability, capable of handling high inrush currents and offering an extended avalanche ruggedness. This robustness ensures stable operation over a wide temperature range and throughout the long lifespan expected of automotive electronics. Its commitment to quality makes it an ideal choice for safety-critical applications like electric power steering (EPS) and anti-lock braking systems (ABS), where failure is not an option.
ICGOODFIND: The Infineon IRF100S201 is a top-tier automotive MOSFET that sets a high standard for power switching. Its combination of ultra-low RDS(on), superior switching performance, and proven automotive robustness makes it an exceptional choice for designers aiming to create more efficient, compact, and reliable next-generation vehicle systems.
