Bourns offers Transient Voltage Suppressor Array combination diodes for surge and ESD
protection applications in an eight 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 will meet IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC
61000-4-5 (Surge) requirements.
