ManualsBrandsST ManualsDiodesSchottky Diode, 2A, 25V, DO-214AA

Features

• Very low forward voltage drop for less power dissipation

• Optimized conduction/reverse losses trade-off which means the highest

efficiency in the applications

• Avalanche rated

• ECOPACK2 compliant

Applications

• Cordless appliance

• SSD

• Battery charger

• Telecom power

• DC / DC converter

Description

Schottky rectifiers designed for high frequency miniature switched mode power

supplies such as adaptors and on board DC/DC converters.

Packaged in SMA Flat Notch or SMB for thermal resistance characteristic

improvement, the STPS2L25 is ideal for use in parallel with MOSFETs in

synchronous rectification.
