Infineon IPP034N08N5AKSA1: 80 V OptiMOS 5 Power MOSFET for High-Efficiency Power Conversion

The continuous drive for higher efficiency and power density in modern electronic systems demands advanced semiconductor solutions. Infineon Technologies addresses this need with the IPP034N08N5AKSA1, an 80 V N-channel Power MOSFET from the cutting-edge OptiMOS™ 5 technology platform. This device is engineered to set new benchmarks in performance for a wide array of power conversion applications.

A key highlight of the IPP034N08N5AKSA1 is its exceptionally low figure-of-merit (FOM), achieved by optimizing the trade-off between on-state resistance (RDS(on)) and gate charge (Qg). With a maximum RDS(on) of just 3.4 mΩ at 10 V, this MOSFET minimizes conduction losses, allowing for more efficient power transfer and reduced heat generation. Simultaneously, its low gate charge ensures swift switching characteristics, which directly translates to lower switching losses at high frequencies. This combination is crucial for designers aiming to push the boundaries of efficiency and operating frequency in their systems.

The benefits of these performance characteristics are vast. In synchronous rectification stages of switch-mode power supplies (SMPS) and DC-DC converters, the device significantly reduces energy loss, contributing to higher overall system efficiency. For industrial applications such as motor drives and robotics, its 80 V drain-source voltage rating provides a robust safety margin and reliable operation in 48 V systems. Furthermore, the MOSFET's high efficiency performance makes it an ideal candidate for solar inverters and battery management systems, where every percentage point of efficiency gain is critical.

Packaged in the robust TO-LL, the IPP034N08N5AKSA1 offers superior thermal performance. This package type enhances power dissipation capabilities, enabling the device to handle high continuous currents while maintaining a lower operating temperature, thereby improving long-term reliability.

ICGOOODFIND: The Infineon IPP034N08N5AKSA1 stands out as a superior component for engineers focused on maximizing efficiency.
