Lightning Surge Protection- SP4022 Series

Description

Applications

The SP4022 series integrates low capacitance steering

diodes with one or two avalanche breakdown diodes for

unidirectional or bidirectional protection, respectively, to

protect against ESD and lightning induced surge events.

These devices can safely absorb up to 15A per IEC

degradation and a minimum ±30kV ESD per IEC61000-

4-2 International Standard. The low loading capacitance

and high surge capability make it ideal for protecting

telecommunication ports such as xDSL and other high

voltage, high speed legacy interfaces.
