Overview
Features ■ Surface Mount SMC package ■ Standoff Voltage: 12 to 58 volts ■ Power Dissipation: 3000 watts ■ RoHS compliant* ■ AEC-Q101 compliant** Applications ■ Protection of power buses ■ Protection of I/O interfaces ■ Overvoltage transient protection ■ Entertainment applications ■ Comfort applications ■ Telecom, computer, industrial and consumer electronics applications SMLJ-Q Transient Voltage Suppressor Diode Series General Information Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection applications, in compact chip package DO-214AB (SMC) size format.
The Transient Voltage Suppressor series offers a choice of Working Peak Reverse Voltage from 12 V up to 58 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.
