Infineon IPD075N03LG: High-Performance 75A OptiMOS Power MOSFET

In the realm of power electronics, efficiency, thermal performance, and reliability are paramount. The Infineon IPD075N03LG stands out as a premier solution, engineered to meet the rigorous demands of modern high-current applications. As part of Infineon’s renowned OptiMOS™ power MOSFET family, this device sets a high benchmark with its exceptional power density and ultra-low on-state resistance.

Designed in a compact D2PAK (TO-263) package, the IPD075N03LG is optimized for high-efficiency DC-DC conversion in applications such as server and telecom power supplies, industrial motor drives, and battery management systems. Its key strength lies in its remarkably low RDS(on) of just 1.7 mΩ (max at 10V), which drastically reduces conduction losses. This allows the MOSFET to handle continuous drain current (ID) up to 75A with minimal heat generation, thereby improving overall system efficiency and thermal management.

Another critical advantage is its enhanced switching performance. The device features low gate charge (QG) and output charge (QOSS), which minimizes switching losses and enables higher switching frequencies. This is particularly beneficial for power supply designs aiming for smaller form factors, as it allows the use of smaller passive components.

Robustness and durability are also central to its design. The IPD075N03LG offers an excellent thermal characteristic and is qualified for automotive-grade applications, ensuring high reliability under stressful operating conditions. Its ability to operate effectively at elevated temperatures makes it a preferred choice for demanding environments.
