Level 4) n Surface Mount SMA package n IEC 61000-4-4 EFT n Standoff Voltage: 5.0 to 495 volts n IEC 61000-4-5 Surge n Power Dissipation: 400 watts n UL Recognized SMAJ Transient Voltage Suppressor Diode Series General Information Agency Recognition The markets of portable communications, computing and video Description equipment are challenging the semiconductor industry to develop increasingly smaller electronic components. 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.
