CD214A-B1xR Series Schottky Barrier Rectifier Chip Diode
General Information
Portable communications, computing and video equipment manufacturers are challenging the
semiconductor industry to develop increasingly smaller electronic components.
Bourns offers Schottky Rectifier Diodes for rectification applications, in a compact chip
package compatible with DO-214AC (SMA) size format. The Schottky Rectifier Diodes offer a
forward current of 1 A with a choice of repetitive peak reverse voltage of 20 V up to 100 V.
