Description G E114 5313 C)
This new device employs advanced HEXFET Power .
MOSFET technology to achieve an unprecedented SO-8 Top View
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 DEVICE CHARACTERlSTlCSS
generation of microprocessors.
IRF7811WPbF
The IRF7811WPbF has been optimized for all parameters
that are critical in synchronous buck converters including RDS(on) 9.0mQ
RDSM, gate charge and Cdv/dt-induced turn-on immunity. Q 22nC
The IRF7811WPbF offers particulary low RDSM and high G
Cdv/dt immunity for synchronous FET applications. st 10.1nC
q,, 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.
