A Suffix of “-C” specifies halogen & lead-free
DESCRIPTION
These miniature surface mount MOSFETs utilize a
high cell density trench process to provide low
R
and to ensure minimal power loss and heat
DS(on)
dissipation. Typical applications are DC-DC converters
and power management in portable and battery-powered
products such as computers, printers, PCMCIA cards,
cellular and cordless telephones.
FEATURES
Low RDS(on) provides higher efficiency and
extends battery life.
Low thermal impedance copper leadframe
SOT-323 saves board space.
Fast switching speed.
High performance trench technology.
