Features ■ RoHS compliant* ■ Surface Mount SMA package ■ Standoff Voltage: 5.0 to 495 volts ■ Power Dissipation: 400 watts ■ UL Recognized Applications ■ IEC 61000-4-2 ESD (Min. Level 4) ■ IEC 61000-4-4 EFT ■ IEC 61000-4-5 Surge SMAJ Transient Voltage Suppressor Diode 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 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.
