General Information
Portable communications, computing and video equipment manufacturers are challenging
the semiconductor industry to develop increasingly smaller electronic components.
Bourns offers small-signal Schottky Barrier Diodes for switching and rectification applications,
in a compact chip package compatible with SOD-123 size format. The Schottky Barrier Diodes
offer a forward current of 1 A with a choice of repetitive peak reverse voltage of 20 V and 40 V.
