International Rectifier IRF6643PbF: DirectFETMOSFET suits a range of dc/dc converters

The 150V IRF6643PbF DirectFET MOSFET targets isolated dc/dc converters operating on 36 to 75V universal-input telecom systems and 48V fixed-input systems. A 35A current rating and a 10V on-resistance of 29 mΩ make the device suitable for high-current synchronous-rectifier sockets. The device can also function as a primary-side MOSFET in isolated or intermediate dc-bus converters, providing a 39-nC Q_G (gate charge) and an 11-nC Q_GD (gate-to-drain charge). Available in an SO-8 package, the IRF6643PbF costs $1.24 (10,000).
