DESCRIPTION
DESCRIPTION
DESCRIPTION
The ST N3446 is the N -Channel enhancement mode power field effect transistor which
is 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.
