Lightning Surge Protection- SP4023 Series

Description

Applications

The SP4023 Series integrates low capacitance steering

diodes with one or two avalanche diodes for unidirectional

or bidirectional protection, respectively, to protect

against ESD and lightning induced surge events. These

components can safely absorb up to 12A per IEC 61000-4-5

2nd Edition (t

and a minimum ±30kV ESD per IEC 61000-4-2 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.

Features

• ESD, IEC 61000-4-2,

±30kV contact, ±30kV air
