VERY SMALL CONDUCTION LOSSES

NEGLIGIBLE SWITCHING LOSSES

EXTREMELY FAST SWITCHING

DESCRIPTION

Single Schottky rectifier suited for switch mode

power supplies and high frequency DC to DC

converters.

SOD-123

Packaged in SOD-123, this device is intended for

use in low voltage, high frequency inverters, free

wheeling and polarity protection applications. Due

to the small size of the package this device fits

GSM and PCMCIA requirements.
