CD1408-R1200~R11000 – Surface Mount Rectifier 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 Rectifier Diodes for rectification applications, in compact
chip package 1408 size format (compatible with SOD87, SOD123 formats), which
offers PCB real estate savings and are considerably smaller than most competitive
parts. The Glass Passivated Rectifier Diodes offer a forward current of 1 A with a
choice of repetitive peak reverse voltage of 200 V up to 1000 V.
Bourns
®
Chip Diodes conform to JEDEC standards, are easy to handle on standard
pick and place equipment and their flat configuration minimizes roll away.
