Bourns offers Transient Voltage Suppressor Array diodes for EFT and ESD
protection applications, in compact chip package SOT23-6 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) and IEC 61000-4-4 (EFT)
requirements.
