DESCRIPTION

The SMxx 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).
