LITTELFUSE SP2502L

TVS Diode Arrays (SPA™ Family of Products)
Lightning Surge Protection - SP2502L Series
SP2502L Series 3.3V 75A Diode Array
RoHS
Pb GREEN
The SP2502L provides overvoltage protection for
applications such as 10/100/1000 Base-T Ethernet and T3/
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.

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 as Telcordia’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 the TeleLink fuse provides
overcurrent protection for the long term 50/60 Hz power
fault events.
