Infineon IAUZ40N06S5N050: 40V, 60A OptiMOS Power MOSFET for High-Efficiency Power Conversion

The continuous demand for higher efficiency and power density in modern electronic systems drives the need for advanced power semiconductor solutions. Infineon Technologies addresses this challenge with the IAUZ40N06S5N050, a 40V, 60A N-channel power MOSFET from its renowned OptiMOS™ 5 power MOSFET family. This device is engineered to set a new benchmark in performance for a wide range of power conversion applications.

A key strength of the IAUZ40N06S5N050 lies in its exceptionally low on-state resistance (RDS(on)), which is specified at a mere 1.5 mΩ maximum. This ultra-low resistance is paramount for minimizing conduction losses, the primary source of power loss when the MOSFET is fully switched on. By drastically reducing these losses, the MOSFET operates cooler, enabling higher efficiency and potentially allowing for the design of more compact systems with reduced heatsinking requirements.

Furthermore, the device features outstanding switching performance. The OptiMOS™ 5 technology ensures low gate charge (Qg) and low figures of merit (e.g., RDS(on) x Qg). This translates to reduced switching losses, which are especially critical in high-frequency applications such as switch-mode power supplies (SMPS), DC-DC converters, and motor drives. The ability to switch rapidly and efficiently allows designers to increase the switching frequency, which in turn permits the use of smaller passive components like inductors and capacitors, thereby increasing overall power density.

The IAUZ40N06S5N050 is housed in an Infineon’s proprietary S5O8 (SuperSO8) package. This package offers a significantly improved footprint compared to standard D2PAK packages while providing superior thermal resistance and power dissipation capabilities. Its compact form factor is ideal for space-constrained applications without compromising on thermal performance or current handling.

Typical applications for this high-performance MOSFET include:

Voltage Regulator Modules (VRMs) and point-of-load (POL) converters in servers and data centers.

Synchronous rectification in switched-mode power supplies (SMPS) for industrial equipment and computing.

Motor control and drive circuits in automotive systems, robotics, and industrial automation.

Battery management systems (BMS) and protection circuits.

ICGOOODFIND: The Infineon IAUZ40N06S5N050 stands out as a superior choice for designers seeking to maximize efficiency and power density. Its combination of ultra-low RDS(on), excellent switching characteristics, and advanced S5O8 packaging makes it an optimal component for demanding power conversion tasks in industrial, computing, and automotive environments.
