Infineon IRFI1310NPBF N-Channel Power MOSFET: Datasheet and Application Overview

The Infineon IRFI1310NPBF is a robust N-Channel power MOSFET designed using advanced silicon technology to meet the demanding requirements of high-power switching applications. This HEXFET® device is renowned for its low on-state resistance (RDS(on)) and high current handling capability, making it a preferred choice in power electronics for both industrial and consumer sectors.

Key Datasheet Parameters and Characteristics

A deep dive into the datasheet reveals the core strengths of this component. The IRFI1310NPBF is characterized by a drain-to-source voltage (VDS) of 100V and a continuous drain current (ID) of 83A at a case temperature of 25°C. This high current rating is supported by an exceptionally low RDS(on) of just 9.5 mΩ, which is a critical factor in minimizing conduction losses and improving overall system efficiency. The device's avalanche ruggedness and fast switching speed ensure reliable operation in harsh environments and high-frequency circuits. Furthermore, its low gate charge simplifies drive circuit design, allowing for faster switching with lower drive current requirements from the controller IC.
