International Rectifier IRF7811WPBF
The IRF7811W has been optimized for all parameters that are critical in synchronous buck converters including RDS(on), gate charge and Cdv/dt-induced turn-on immunity. The IRF7811W offers particulary low RDS(on) and high Cdv/ dt immunity for synchronous FET applications. The package is designed for vapor phase, infra-red, convection, or wave soldering techniques.DESCRIPTION
This new device employs advanced HEXFET Power MOSFET technology to achieve an unprecedented balance of on-resistance and gate charge. The reduced conduction and switching losses make it ideal for high efficiency DC-DC converters that power the latest generation of microprocessors. Power dissipation of greater than 3W is possible in a typical PCB mount application.
