TPN3021

Tripolar overvoltage protection for network interfaces

Features

■ Triple crowbar protection

■ Low capacitance

■ Low holding current: I_H= 30 mA minimum

■ Surge current:

– I_PP= 200 A, 2/10 µs

– I_PP= 30 A, 10/1000 µs

Main applications

Dedicated to data line protection, this device

provides a tripolar protection function. It ensures

the same protection capability with the same

breakdown voltage in both common and

differential modes.

SO-8

Description

Schematic diagram

The TPN3021 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.

Rx+ / Tx+

Benefits

Trisil technology is not subject to ageing and

provides a fail safe mode in short circuit for a

better protection. They are used to help

equipment to meet main standards such as

UL1950, IEC950 / CSA C22.2 and UL1459. They

have UL94 V0 ap-proved resin. SO8 package is

JEDEC registered.

GND

Rx- / Tx-

Trisils comply with the following standards GR-

1089 Core, ITU-T-K20/K21, VDE0433, VDE0878,

IEC61000-4-2.
