GND GND GND TVS Diode Array (SPA Diodes) Lightning Surge Protection - SP2574NUTG RoHS Pb GREEN SP2574NUTG 2.5V 40A Diode Array Description The SP2574NUTG is a low-capacitance, TVS Diode Array designed to provide protection against ESD (electrostatic discharge), CDE (cable discharge events), EFT (electrical fast transients), and lightning induced surges for high- speed, differential data lines. Its packaged in a DFN package (3.0 x 2.0mm) and each component can protect up 4 channels or 2 differential pairs, up to 40A (IEC 61000-4-5) and up to 30kV ESD (IEC 61000-4-2). The flow-through design minimizes signal distortion, reduces voltage overshoot, and provides a simplified PCB design. The SP2574NUTG with its low capacitance and low clamping voltage makes it ideal for high-speed data interfaces such as 1GbE applications found in notebooks, switches, etc. Pinout Features Top View Bottom View ESD, IEC 61000-4-2, DFN-10 package is 30kV contact, 30kV air optimized for high-speed 1 2 3 4 5 10 9 8 7 6 data line routing EFT, IEC 61000-4-4, 40A (5/50ns) Provides protection for two differential data pairs Lightning, 40A (8/20s as (4 channels) up to 40A defined in IEC 61000-4-5 2nd Edition) Low operating and clamping voltage Low capacitance of 1 2 3 4 5 10 9 8 7 6 3.8pF 0V (TYP) per I/O AEC-Q101 qualified NOTE: PIN3, PIN8 are same potential with GND Low leakage current of 0.1A (TYP) at 2.5V Functional Block Diagram Applications 10/100/1000 Ethernet LVDS Interfaces LINE1 IN (Pin 1) LINE1 OUT (Pin 10) WAN/LAN Equipment Integrated Magnetics Desktops, Servers and Smart TV LINE2 IN (Pin 2) LINE2 OUT (Pin 9) Notebooks Application Example RJ -45 Connector Ethernet PHY GND GND TP0+ TP0- TP1+ LINE3 IN (Pin 4) LINE3 OUT (Pin 7) TP1- TP2+ TP2- LINE4 OUT (Pin 6) LINE4 IN (Pin 5) TP3+ TP3- SP2574N 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. 2019 Littelfuse, Inc.
