CDNBS08-SR721

Manufacturer Part Number
CDNBS08-SR721
Description
Steering Diode Arrays
Manufacturer
Bourns, Inc.
Datasheet
The CDNBS08-SR721 device provides ESD, EFT and Surge protection
for external ports meeting IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT)
and IEC 61000-4-5 (Surge) requirements.
The Steering Diode array provides up to 6 lines of protection using the
“rail to rail” clamping technique with low leakage current and low
capacitance per line. The device is available in a JEDEC SO-8 package
and is intended to be mounted directly onto an FR4 printed circuit
board.
