DESCRIPTION
The SDxx Series is designed for applications requiring transient overvoltage protection capability.
They are intended for use in voltage and ESD sensitive equipment such as computers, printers,
business machines, communication systems, medical equipment and other applications. These devices
are ideal for situations where board space is at a premium.
This series has been specifically designed to protect sensitive components which are connected to
power
、
data and transmission lines from overvoltage caused by ESD(electrostatic discharge), CDE
(Cable Discharge Events),and EFT (electrical fast transients).
Features
350 Watts Peak Pulse Power per
