Power MOSFET Knock Efficiency Up A Notch

The first two members a family of DirectFET plus power MOSFETs, the 25V IRF6811 and IRF6894, reduce on-state resistance and gate charge compared to previous generation devices to significantly improve efficiency up to 2%. The IRF6811 control MOSFET is available in a small can while the IRF6894 synchronous MOSFET is offered in a medium can. The IRF6894 also features a monolithically integrated Schottky that reduces losses associated with body diode conduction and reverse recovery. Pricing for the IRF6811STRPBF and IRF6894MTRPBF begins at $0.75 and $1.75 each/10,000, respectively. For more information, contact Sian Cummins at INTERNATIONAL RECTIFIER CORP., El Segundo, CA.
