Infineon IPB020NE7N3G OptiMOS 3 Power MOSFET: Datasheet, Application Notes, and Performance Characteristics

The Infineon IPB020NE7N3G is a state-of-the-art N-channel Power MOSFET belonging to the renowned OptiMOS™ 3 technology family. Designed for exceptional efficiency and reliability in demanding power conversion applications, this component sets a high standard for performance in a compact D²PAK (TO-263) package. It is engineered to minimize losses and maximize power density, making it an ideal choice for modern switch-mode power supplies (SMPS), motor control, and synchronous rectification circuits.

A deep dive into its datasheet reveals a robust set of specifications. The device is rated for a drain-source voltage (VDS) of 30 V, making it perfectly suited for low-voltage, high-current applications such as server and telecom power systems. A standout feature is its extremely low typical on-resistance (RDS(on)) of just 0.95 mΩ at 10 V gate-source voltage. This ultra-low resistance is the key to its high efficiency, as it directly translates to reduced conduction losses and lower heat generation. Furthermore, the MOSFET offers a continuous drain current (ID) of 120 A, showcasing its ability to handle significant power levels.

The performance characteristics of the IPB020NE7N3G are defined by its superior switching behavior. The OptiMOS 3 technology ensures low gate charge (QG) and low effective output capacitance (COSS(eff)). These parameters are critical for achieving high switching frequencies, which allows designers to reduce the size of magnetic components and capacitors, thereby increasing the overall power density of the end system. The low FOM (Figure of Merit) of RDS(on) QG ensures an excellent balance between conduction and switching losses.
