SPN8439
N-Channel Enhancement Mode MOSFET
DESCRIPTION
The SPN8439 is the N-Channel logic enhancement mode
power field effect transistors are produced using high cell
density , DMOS trench technology.
This high density process is especially tailored to
minimize on-state resistance.
These devices are particularly suited for low voltage
application such as cellular phone and notebook
computer power management and other battery powered
circuits, and low in-line power loss are needed in a very
small outline surface mount package.
