*
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 diodes for surge and
ESD protection applications in an eight lead narrow body SOIC package size format.
TheTransient Voltage Suppressor Array series offer a choice of voltage types ranging
from 3 V to 36 V in unidirectional and bidirectional configurations. 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.
