CD214A-B220 ~ B260 Schottky Barrier Rectifier Chip Diode
General Information
The markets of portable communications, computing and video equipment are challenging the semiconductor industry to develop increasingly
smaller electronic components.
Bourns offers Schottky Rectifier Diodes for rectification applications, in compact chip package DO-214AC (SMA) size format, which offer PCB
real estate savings and are considerably smaller than competitive parts. The Schottky Rectifier Diodes offer a forward current of 2 A with a
choice of repetitive peak reverse voltage of 20 V up to 60 V.
Bourns
®
Chip Diodes conform to JEDEC standards, easy to handle on standard pick and place equipment and their flat configuration makes
roll away much more difficult.
