Overview

Description

The STPS3150UY is a dual Schottky rectifier diode designed for high-efficiency power applications. Key features include:
- Low forward voltage drop (typically 0.49V at 15A), reducing power losses.
- High current capability (15A per diode) and low thermal resistance for improved heat dissipation.
- Ultrafast switching with minimal reverse recovery time, enhancing performance in switching power supplies.
- Common cathode configuration, making it suitable for synchronous rectification in DC-DC converters.
- AEC-Q101 qualified, ensuring reliability for automotive applications.
Common uses include AC-DC converters, motor control, and freewheeling diodes in power systems. Packaged in a TO-263 (D²PAK), it offers robust thermal and electrical performance.
