## BOURNS ~~Ee~~ **CDNBS08-SRDAxx-4 Series - Steering Diode/TVS Array Combo** 

## ~~**General Information**~~ 

The markets of portable communications, computing and video equipment are challenging the semiconductor industry to develop increasingly smaller electronic components. 

Bourns offers Steering Diode/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.
