The SMxxOC 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).
