NSR0520
SCHOTTKY BARRIER DIODE
SOIC-8
Schottky barrier diodes are optimized for very low forward voltage drop and low leakage current and are used in
a wide range of dc-dc converter, clamping and protection application in portable devices. NSR0520 in a SOD-523
miniature package enables designers to meet the challenging task of achieving higher effciency and meeting
reduced space requirements.
