25V DirectFET MOSFETs for embedded CPU power
International Rectifier has introduced three new 25V DirectFET MOSFETs.
The latest device in IR's DirectFET line-up minimizes conduction, switching and reverse-recovery losses by continuing to improve the critical parameters that determine the performance of power MOSFETs, RDS(on), Qg and Qgd.
These improvements enable operation at higher current levels, while maintaining the smaller form factor of a single MOSFET.
By reducing board space by more than 50%, a single DirectFET MOSFET now can take the place of two or three SO-8 packages.
The device's extremely low typical 10V RDS(on) of 29 mOhms and low inductance makes it well suited for high-current synchronous rectifier sockets.
Also, with its very low 39 nC Qg and 11 nC Qgd, the IRF6643TRPbF functions well as a primary-side MOSFET in isolated or intermediate DC bus converters.
The IRF6643TRPbF is packaged in the medium-sized (MZ) DirectFET package.
