Lightning Surge Protection - SP2502L Series

RoHS

GREEN

SP2502L Series 3.3V 75A Diode Array

Description

The SP2502L provides overvoltage protection for

applications such as 10/100/1000 Base-T Ethernet andT3/

E3 interfaces. This device has a low capacitance of only

5pF making it suitable for PHY side Ethernet protection

and the capability to protect against both longitudinal and

differential transients. Furthermore, the SP2502L is rated

up to 100A (tp=2/10µs) making it suitable for line side

protection as well against lightning transients as deﬁned

by GR-1089 (intra-building), ITU, YD/T, etc. The application

schematic provides the connection information for a PHY

side protection scheme of a single differential pair.

Pin 4 and 5

The schematic shows protection for a single differential

pair as part of a larger high-speed data interface such as

Ethernet. The SP2502L provides both metallic (differential)

and longitudinal (common mode) protection from lightning

induced surge events as speciﬁed by regulatory standards

such asTelcordia’s GR-1089 CORE and ITU K.20 and 21.

Life Support Note:

Not Intended for Use in Life Support or Life Saving Applications

The products shown herein are not designed for use in life sustaining or life saving

applications unless otherwise expressly indicated.

The SP2502L protects against both positive and negative

induced surge events while theTeleLink fuse provides

overcurrent protection for the long term 50/60 Hz power

fault events.
