The IRF6646 is an N-channel Power MOSFET optimized for primary switching in isolated DC-DC converters and secondary-side synchronous rectification, housed in a DirectFET MN package with a height of 0.7 mm. It has a maximum drain-to-source voltage of 80 V and a gate-to-source voltage rating of ±20 V. The device features a typical on-resistance of 7.6 mΩ at 10 V gate drive and 12 A drain current, with a total gate charge of 36 nC. It supports dual-sided cooling, is compatible with standard surface mount techniques, and meets RoHS and lead-free (up to 260°C reflow) requirements. The package allows for high thermal performance with a junction-to-case thermal resistance of 1.4 °C/W, and it complies with AEC-Q200 qualification standards.
