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.

2 Typical fast response times are less than picoseconds for unidirectional devices and less than 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.
