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.

DEVICE CHARACTERISTICSꢀ  
IRF7811WPbF  
The IRF7811WPbF has been optimized for all parameters  
that are critical in synchronous buck converters including  
RDS  
QG  
9.0mΩ  
22nC  
(on)  
RDS(on), gate charge and Cdv/dt-induced turn-on immunity.  
The IRF7811WPbF offers particulary low RDS(on) and high  
Cdv/dt immunity for synchronous FET applications.  
Qsw  
10.1nC  
12nC

The package is designed for vapor phase, infra-red,  
convection, or wave soldering techniques. Power  
dissipation of greater than 3W is possible in a typical  
PCB mount application.
