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 fl at confi guration 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.
