IRFR7446 is an N-channel power MOSFET rated for 40 V drain-to-source breakdown voltage, designed for brushed and BLDC motor drives, synchronous rectification, and DC/DC conversion. It is packaged in a D-PAK case with a maximum continuous drain current of 56 A limited by the package, and a silicon-limited current of 120 A at 25°C. The typical drain-to-source on-resistance is 3.0 mΩ at 10 V gate voltage and 56 A drain current. The device meets RoHS standards and is lead-free. Maximum junction temperature is 175°C, with thermal resistance from junction-to-case of 1.52 °C/W and junction-to-ambient of 50 °C/W when mounted on a PCB. It complies with AEC-Q200 qualification standards.
