Description
These N and P channel MOSFETs from International Rectifier utilize advanced
processing techniques to achieve the extremely low on-resistance per silicon
area. This benefit provides the designer with an extremely efficient device for
use in battery and load management applications.
This Dual TSOP-6 package is ideal for applications where printed circuit
board space is at a premium and where maximum functionality is required.
With two die per package, the IRF5851 can provide the functionality of two
SOT-23 packages in a smaller footprint. Its unique thermal design and
R
DS(on)
reduction enables an increase in current-handling capability.
