Power Schottky rectifier

Main product characteristics

Feature and benefits

forward voltage drop

Description

Dual center tap Schottky rectifier suited for high

frequency Switch Mode Power Supply.

intended to be used in notebook and LCD

adaptors, desktop SMPS, providing in these

applications a margin between the remaining

voltages applied on the diode and the voltage

capability of the diode.
