24-01-07 -- International Rectifier has launched the IRF6643PbF, a 150V DirectFET MOSFET for isolated DC-DC converters operating from a wide range, 36V to 75V universal telecommunications input and 48V fixed input systems. Combining IR’s advanced DirectFET packaging technology and its HEXFET power MOSFET silicon, the new DirectFET device achieves a current rating up to 35 amperes. By reducing board space a single DirectFET MOSFET now can take the place of two or three SO-8 packages. The device’s typical 10V RDS(on) of 29 mOhms makes it suited for high-current synchronous rectifier sockets. Also, with its 39nC Qg and 11nC Qgd, the IRF6643TRPbF functions as a primary-side MOSFET in isolated or intermediate DC bus converters. The IRF6643TRPbF is packaged in the medium-sized (MZ) DirectFET package.
