The IRF6643TRPBF is an N-Channel MOSFET from Infineon Technologies, specifically designed for Class-D audio amplifier applications. It features a drain-source voltage of 150V and a continuous drain current of 35A at Tc=25°C (6.2A at Ta=25°C). The device offers a typical on-resistance of 29 mOhm and a maximum of 34.5 mOhm at Vgs=10V, ensuring high efficiency. Gate charge is optimized with a typical value of 39 nC and maximum of 55 nC, contributing to improved total harmonic distortion (THD) and efficiency. The MOSFET also features low internal gate resistance (0.9 Ohm typical) and low Qrr for reduced EMI. Packaged in the DirectFET Isometric MZ package, it supports surface mount assembly and dual-sided cooling for enhanced thermal performance. The device is RoHS compliant, halogen-free, and lead-free qualified up to 260°C reflow. Operating temperature range is -40°C to 150°C junction.
