Description
150 V power Schottky rectifier are suited for switch mode power supplies on up to 24
V rails and high frequency converters.
Packaged in axial, SMB, SMA Flat Notch and SMB Flat, the
STPS3150
is ideal for
use in consumer and computer applications like TV, STB, PC and DVD where low
drop forward voltage is required to reduce power dissipation.
