CDNBS08-T03~T36C – TVS Diode Array Series
General Information
The markets of portable communications, computing and video equipment are
challenging the semiconductor industry to develop increasingly smaller electronic
components.
Bourns offers Transient Voltage Suppressor Array diodes for surge and ESD
protection applications, in 8 lead narrow body SOIC package size format. The
Transient 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.
