ULVF™ power Schottky rectifier

Features

■ High current capability

■ Ultralow forward voltage drop

■ Low thermal resistance

■ High frequency operation

■ High integration

Description

The STPS30U100DJF is a power Schottky rectifier featuring an ultralow forward voltage drop (ULVF), suited for high frequency switch mode power supply and DC to DC converters.

Packaged in PowerFLAT™, this device is intended to be used in notebook, game station and desktop adapters, providing these applications with good efficiency at both low and high load. Its low profile was especially designed to be used in applications with space-saving constraints.
