Surface Mount

Schottky Power Rectifier

SOD−123 Power Surface Mount Package

The Schottky Power Rectifier employs the Schottky Barrier

principle with a barrier metal that produces optimal forward voltage

drop−reverse current tradeoff. Ideally suited for low voltage, high

frequency rectification, or as a free wheeling and polarity protection

diodes in surface mount applications where compact size and weight

are critical to the system. This package provides an alternative to the

leadless 34 MELF style package.

Features

• Guardring for Stress Protection

• Very Low Forward Voltage

• Epoxy Meets UL 94 V−0 @ 0.125 in

• Package Designed for Optimal Automated Board Assembly

• Pb−Free Packages are Available

Mechanical Characteristics
