Infineon IPB80N06S4-05: Key Specifications and Application Overview
The Infineon IPB80N06S4-05 is a benchmark N-channel power MOSFET engineered with the renowned OptiMOS technology, setting a high standard for efficiency and reliability in power conversion and management applications. This device is specifically designed to offer an optimal blend of low on-state resistance and high switching performance, making it a preferred choice for a wide array of demanding electronic systems.
A central feature of this MOSFET is its exceptionally low on-state resistance (R DS(on)) of just 4.5 mΩ (max. at V GS = 10 V). This ultra-low resistance is pivotal in minimizing conduction losses, which directly translates to higher system efficiency, reduced heat generation, and the potential for more compact designs with smaller heat sinks. The component is rated for a drain-source voltage (V DS) of 60 V and a continuous drain current (I D) of 80 A at a case temperature of 25°C, providing robust performance for high-current paths. Its low gate charge (Q G) further enhances its appeal by enabling very fast switching speeds, which is critical for high-frequency operations that reduce the size of passive components like inductors and capacitors.
Housed in the space-efficient TO-263 (D2PAK) surface-mount package, the IPB80N06S4-05 is perfectly suited for automated PCB assembly. This package offers an excellent balance between power handling capability and board space savings, making it ideal for modern, dense power electronics.
