Infineon IPB180N04S4-H0 OptiMOS 5 Power MOSFET: Features and Applications

The Infineon IPB180N04S4-H0 is a state-of-the-art power MOSFET belonging to the OptiMOS™ 5 40 V family, engineered to deliver exceptional efficiency and power density in a wide array of modern power management applications. This N-channel MOSFET is designed with the goal of minimizing power losses while offering superior switching performance, making it a preferred choice for designers striving for higher system efficiency and compactness.

A standout feature of this device is its extremely low typical on-state resistance (RDS(on)) of just 0.18 mΩ. This remarkably low value is crucial for reducing conduction losses, which directly translates into higher efficiency, less heat generation, and the potential for smaller heatsinks or simplified thermal management. Furthermore, the OptiMOS 5 technology ensures outstanding switching performance, allowing for higher switching frequencies. This enables the use of smaller passive components like inductors and capacitors, contributing to a significant reduction in the overall size and weight of the power supply unit.

The MOSFET is housed in an SuperSO8 (SSO-8) package, which offers an excellent balance between a compact footprint and effective thermal performance. This package is ideal for space-constrained applications while still providing robust power handling capabilities.

Key Applications

The combination of high efficiency, low RDS(on), and fast switching speed makes the IPB180N04S4-H0 exceptionally versatile. Its primary applications include:
