Unidirectional TVS Diodes

Description

The SDxxC Series is designed for applications requiring transient over voltage 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,

date and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE(Cable

Discharge Events), and EFT (electrical fast transients).
