Infineon IPZ40N04S5L-7R4: 40V OptiMOS 5 Power MOSFET with 4mΩ RDS(on)

In the realm of power electronics, efficiency and thermal performance are paramount. The Infineon IPZ40N04S5L-7R4 stands out as a premier solution, representing the cutting-edge OptiMOS™ 5 40V technology platform. This Power MOSFET is engineered to deliver exceptional performance in a compact form factor, making it an ideal choice for a wide array of demanding applications, from automotive systems to high-density DC-DC converters.

The most striking feature of this MOSFET is its extremely low on-state resistance of just 4mΩ (max). This ultra-low RDS(on) is a game-changer, as it directly translates to minimal conduction losses during operation. When a device allows more current to pass with less resistance, less energy is wasted as heat. This inherent efficiency is crucial for improving the overall system efficiency, extending battery life in portable devices, and reducing the need for large and costly heat sinks, thereby saving both space and bill-of-materials (BOM) costs.

Furthermore, the IPZ40N04S5L-7R4 boasts an outstanding figure-of-merit (FOM), which balances low on-resistance with low gate charge (Qg). This superior switching performance ensures that the transistor can turn on and off very quickly, which is critical for high-frequency switching applications like switch-mode power supplies (SMPS) and motor control circuits. Faster switching allows for the use of smaller passive components, such as inductors and capacitors, further contributing to higher power density designs.

Housed in the space-saving Infineon S3O8 (SuperSO8) package, this component demonstrates that high power handling does not require a large footprint. The package offers superior thermal characteristics and a very low parasitic inductance, which is essential for maintaining stability and performance in high-speed switching environments. Its rugged design also ensures high reliability under strenuous conditions, including high operating temperatures.

ICGOOFind: The Infineon IPZ40N04S5L-7R4 is a benchmark in power semiconductor technology, offering designers a potent combination of ultra-low resistance, high switching speed, and excellent thermal performance in a miniaturized package. It is a top-tier component for engineers striving to push the boundaries of efficiency and power density in modern electronic systems.
