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.
