TO-220AC

Features

• High junction temperature capability

• Avalanche rated

• Low leakage current

• Good trade-off between leakage current and forward voltage drop

• ECOPACK

2 compliant

Applications

• Switching diode

• SMPS

• DC/DC converter

• LED lighting

• Notebook adapter

Description

This single Schottky rectifier is suited for high frequency switch mode power supply.

Packaged in TO-220AC, the STPS20120D is optimized for use in notebook & LCD

adaptors, desktop SMPS, providing in these applications a margin between the

remaining voltages applied on the diode and the voltage capability of the diode.
