STT3998N
Dual N-Ch Enhancement Mode Mos.FET
3.7 A, 20 V, RDS(ON) 58 m
RoHS Compliant Product
A suffix of “-C” specifies halogen and lead-free
DESCRIPTION
These miniature surface mount MOSFETs utilize a high cell density
trench process to provide low RDS(on) and to ensure minimal power
loss and heat 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) provide higher efficiency and extends battery
life.
Low thermal impedance copper leadframe TSOP-6 saves
board space.
Fast switching speed.
High performance trench technology.
