Featuring low forward voltage drop and negligible recovery, ST's Schottky diodes ensure higher switching speeds and better system efficiency from 15 up to 200 V. Made of robust avalanche capable technologies, many are available in both industrial and automotive versions.
With several series with forward voltage drops from 15 to 200 V, our small-signal and power Schottky diodes ensure the best efficiency for your applications. Recent packages development are 1mm-thick SMA Flat and SMB Flat packages as well as our latest D²PAK and PowerFLAT™ packages for enhanced power density. For other compact designs, many devices are tightly packed surface-mount devices or using through-hole encapsulation. Featuring a robust avalanche performance, ST Schottky diodes are rated for use in switched-mode power supplies (SMPS).
To ensure the most efficient, compact and rugged solutions for power conversion applications, ST provides a useful set of tools to help engineers get the most from their designs.
The ST Diode Finder mobile app is a user-friendly product selector ensuring a smooth and simple navigation experience and includes a parametric search engine that lets you rapidly identify the right product that best fits your application.
Our online, waveform-driven, Schottky & FERD eTool simulator is a simple, straightforward way to calculate power losses when selecting Schottky or field-effect rectifier diodes (FERD) and further optimize your designs.
Applications
ST’s Schottky diodes are suitable for semi-slim or slim-type notebook adapters, solar panel junction boxes, power converters, low voltage OR-ing and 48 V converters, welding equipment, and LED lighting as well as automotive applications.
Product types
ST’s Schottky barrier diodes are available in small-signal and power Schottky. They are divided in 3 subfamilies:
Featuring low forward voltage drop and zero or negligible recovery charges, these diodes are available in packages suited for a wide range of applications from 3 A SMA flat surface-mount devices for LED supply circuits up to 3 A TO-277A packages for automotive auxiliary converters and isolated 240 A ISOTOP packages for welding systems.
Our portfolio of small-signal Schottky barrier diodes offer forward voltages from 200 mV to 1 V with repetitive peak reverse voltages from 10 to 100 V in packages ranging from axial devices to chip scale package (CSP) perfect for smartphones, handhelds and wearables.
