STPS3L25S is a low drop power Schottky rectifier from STMicroelectronics. It features a very low forward voltage drop for less power dissipation, optimized conduction/reverse losses trade-off for the highest efficiency in applications, and high power surface mount miniature package. It is especially intended for use as an antiparallel diode on synchronous rectification freewheel MOSFET’s at the secondary of 3.3V SMPS and DC/DC units.
This document is a technical datasheet for the STPS3L25S single Schottky rectifier. It describes the device as being suited for Switched Mode Power Supplies (SMPS) and high frequency DC to DC converters, specifically intended for use as an antiparallel diode on synchronous rectification freewheel MOSFETs at the secondary of 3.3V SMPS and DC/DC units.
