Infineon IPD90N06S4L03ATMA2: High-Performance OptiMOS Power MOSFET for Automotive Applications

The relentless drive towards vehicle electrification, from advanced driver-assistance systems (ADAS) to efficient powertrains, demands power semiconductors that deliver uncompromising performance, reliability, and efficiency. Addressing these critical needs, the Infineon IPD90N06S4L03ATMA2 stands out as a premier OptiMOS power MOSFET engineered specifically for the rigorous demands of the automotive industry.

This N-channel MOSFET is built on Infineon’s advanced OptiMOS technology platform, which is renowned for its exceptional balance of low switching losses and high robustness. The device is characterized by a very low maximum on-state resistance (RDS(on)) of just 3.0 mΩ at a gate-source voltage of 10 V. This ultra-low resistance is pivotal in minimizing conduction losses, which directly translates into higher system efficiency, reduced heat generation, and the potential for smaller cooling solutions. Such efficiency is paramount in electric vehicles (EVs) and hybrid electric vehicles (HEVs), where every watt saved extends driving range and improves performance.

Beyond raw efficiency, the IPD90N06S4L03ATMA2 is designed for superior switching performance. The low gate charge (Qg) and optimized internal capacitances ensure fast switching speeds. This is crucial for high-frequency applications like DC-DC converters and motor control inverters, allowing for higher power density and more compact designs by enabling the use of smaller passive components.

As an automotive-grade component, this MOSFET adheres to the stringent AEC-Q101 qualification standard, guaranteeing its reliability and performance under the harsh conditions typical of automotive environments. It is capable of operating reliably over a wide temperature range and is resistant to various stress factors, including thermal cycling and humidity. Furthermore, its high avalanche ruggedness enhances system-level reliability, providing robust protection against voltage spikes and inductive load switching events that are common in automotive electrical systems.

Typical applications are extensive and critical to modern vehicles. They include:

BLDC motor control for pumps, fans, and window lifters.

DC-DC conversion in 12/48 V systems and onboard chargers.

Load and solenoid switching in body control modules.

Battery management systems (BMS) for disconnection units.
