Schottky barrier diodes for low voltage applications

Schottky barrier diodes for low voltage applications
Suitable for use with DC/DC converters and in low voltage applications, particularly in hand-held and portable equipment, the XBS104P11R-G, XBS304F11R-G and XBS306P11R-G Schottky barrier diodes have been announced by Torex Semiconductor. Schottky barrier diodes offer much lower forward voltage drop than standard switching diodes which means that they can offer high current capabilities, ultra fast switching and low power dissipation.
