STPS1150

Power Schottky rectifier

Features

■ Negligible switching losses

■ Low forward voltage drop for higher efficiency

and extented battery life

■ Low thermal resistance

■ Surface mount miniature package

■ Avalanche capability specified

Description

These 150 V power Schottky rectifiers are suited

for switch mode power supplies on up to 24 V rails

and high frequency converters.

Packaged in STmite/STmite flat, SMA and axial,

this device is intended for use in consumer and

computer applications like TV, STB, PC and DVD

where low drop forward voltage is required to

reduce power dissipation.
