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. Pinout Features 1 8 2 7 • Clamping speed of nanoseconds • Lightning protection, IEC61000-4-5, 75A (8/20µs) • SOIC-8 surface mount package (JEDEC MS-012) • Low clamping voltage 3 6 • Low insertion loss, loglinear capacitance 4 5 • Combined longitudinal and metallic protection • UL 94V-0 epoxy molding • RoHS compliant SOIC-8 (Top View) Note: Pinout diagrams above shown as device footprint on circuit board. Functional Block Diagram Line in Pin 1 and 8 Applications Line out • T1/E1 Line cards • T3/E3 and DS3 Interfaces • 10/100/1000 BaseT Ethernet • STS-1 Interfaces Application Example Pin 2, 3, 6, and 7 1 8 2 7 3 6 TeleLink (0461 1.25) to chipset (Ethernet PHY, T3/E3 PHY, etc.) 5 4 Line out Line in SP2502L 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 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. ©2012 Littelfuse, Inc.
