LT3021

Tripolar Overvoltage Protection for Network Interfaces

General Description

The LT3021 is a low capacitance transient

surge arrestor designed for protection of high debit

rate communication network. Its low capacitance

avoids distorsion of the signal as it has been

designed for T1/E1 and Ethernet networks.

Applications

Dedicated to dataline protection, this device

provides a tripolar protection function. It ensure the

same

protection

capability

with

the

same

breakdown

voltage

in

both

common

and

differential modes.

Features

Tripolar crowbar protection

Low capacitance

Repetitive peak pulse current:

Ipp=30A (10/1000μs)

Low holding current: IH=30mA

Revision:B

SO-8
