CDNBS16-SR720 – Steering Diode Arrays
General Information
The CDNBS16-SR720 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 14 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-16 package
and is intended to be mounted directly onto an FR4 printed circuit
board.
