SMAJ-Q Transient Voltage Suppressor Diode Series
General Information
Additional Information
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 220 V.
Typical fast response times are less than 1.0 picosecond from 0 V to 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.
