The IRF7946TRPBF is a 40V N-Channel power MOSFET from Infineon Technologies, part of the StrongIRFET family. It features a maximum continuous drain current of 198A at 25°C and 125A at 100°C, with a typical on-resistance of 1.1 mΩ at VGS=10V. The device is designed for high-efficiency power conversion applications such as brushed and brushless DC motor drives, DC/DC converters, and synchronous rectifier circuits. The DirectFET MX package offers low thermal resistance (junction-to-case 1.3°C/W) and enables surface mount assembly. The device is RoHS and halogen-free compliant.
