| PL IA Features Applications NT Lead free device (RoHS compliant*) Protects up to 4 I/O ports Unidirectional configuration ESD protection Low capacitance 3 pF Ethernet - 10/100/1000 Base T Personal digital assistant Handheld electronics Cellular phones Video cards *R oH S CO M CDNBS08-SLVU2.8-4 - Low Capacitance TVS Array 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 Array combination diodes for surge and ESD protection applications in an 8 Lead Narrow Body SOIC package size format. Bourns Chip Diodes conform to JEDEC standards, are easy to handle on standard pick and place equipment and their flat configuration minimizes roll away. The Bourns device(R) will meet IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC 61000-4-5 (Surge) requirements. 1 2 3 4 8 7 6 5 Electrical Characteristics (@ TA = 25 C Unless Otherwise Noted) Parameter Peak Pulse Current (tp = 8/20 s) Peak Pulse Power (tp = 8/20 s)1 Working Voltage Breakdown Voltage @ 1 mA Leakage Current @ VWM Capacitance @ 0 V, 1 MHz Snapback Voltage @ IPP = 2 A @ IPP = 5 A Clamping Voltage @ IPP = 24 A @ IPP = 30 A Note: 1.
