General Information
Portable communications, computing and video equipment manufacturers are
challenging the semiconductor industry to develop increasingly smaller electronic
components.
Bourns offers Schottky Rectier Diodes for rectication applications, in a compact chip
package compatible with DO-214AA (SMB) size format, which offer PCB real estate
savings and are considerably smaller than competitive parts. The Schottky Rectier
Diodes offer a forward current of 2 A with a choice of repetitive peak reverse voltage of
20 V up to 100 V.
