CD0402-TxxC – TVS Diode Array Series
General Information
The markets of portable communications, computing and video equipment are
challenging the semiconductor industry to develop increasingly smaller electronic
components.
Bourns offers Transient Voltage Suppressor Array diodes for surge and ESD
protection applications, in 0402 chip package size format. The Transient Voltage
Supressor Array series offers a choice of voltage types ranging from 3 V to 36 V in a
bidirectional configuration. Bourns
®
Chip Diodes conform to JEDEC standards, are
easy to handle on standard pick and place equipment and their flat configuration
minimizes roll away.
The Bourns
®
device will meet IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC
61000-4-5 (Surge) requirements.
