STPS5L25 Low drop power Schottky rectifier Datasheet − production data Description Single Schottky rectifier suited for switch mode power supply and high frequency DC to DC converters. Packaged in DPAK, this device is intended for use as a rectifier at the secondary of 3.3 V SMPS units. Table 1. Device summary Symbol Features • Very low forward voltage drop for less power dissipation and reduced heatsink • Optimized conduction/reverse losses trade-off which means the highest efficiency in the applications • High power surface mount miniature package • Avalanche specification • ECOPACK®2 compliant component for DPAK on demand January 2015 This is information on a product in full production.
