General Information
Agency Recognition
The markets of portable communications, computing and video
equipment are challenging the semiconductor industry to develop
increasingly smaller electronic components.
Description
UL
File Number: E153537
Bourns offers Transient Voltage Suppressor Diodes for surge and
ESD protection applications, in compact chip package DO-214AC
(SMA) size format. The Transient Voltage Suppressor series offers a choice of Working Peak Reverse Voltage from 5 V up to 495 V and
Breakdown Voltage up to 550 V. Typical fast response times are less than 1.0 picoseconds for unidirectional devices and less than 5.0
picoseconds for bidirectional devices from 0 V to Minimum Breakdown Voltage.
Bourns® Chip Diodes conform to JEDEC standards, are easy to handle with standard pick and place equipment and the flat configuration
minimizes roll away.
