TVS Diode Arrays (SPA Diodes) Lightning Surge Protection - SP3051 Series RoHS Pb GREEN SP3051 Series 6V 20A Diode Array Description The SP3051 integrates low capacitance rail-to-rail diodes with an additional zener diode to protect each I/O pin against ESD and high surge events. This robust component can safely absorb 20A of current per IEC 61000-4-5 (t =8/20s) without performance degradation P nd and a minimum 30kV ESD rating per IEC 61000-4-2 2 edition. Their very low off-state capacitance is compatible with high speed circuits. Features ESD, IEC 61000-4-2, L ow off-state capacitance 30kV contact, 30kV air of 3.8pF (TYP) per I/O EFT, IEC 61000-4-4, 40A Low leakage current of Pinout (5/50ns) 0.5A (MAX) at 5V Lightning, 20A (8/20s as Small SOT23-6 (JEDEC I/O 4 defined in IEC 61000-4-5 MO-178AB) packaging I/O 1 nd 2 edition) GND V CC Applications LCD/PDP TVs Firewire I/O 2 I/O 3 Monitors Set Top Boxes Notebooks Flat Panel Displays Functional Block Diagram 10/100/1000 Ethernet Portable Medical RJ45 10/100 Ethernet Differential Protection Unused 6 5 4 TX + Application Examples Unused TX + 10/100 TX - USB Dual Port Protection V Ethernet BUS 6 1 V PHY R T BUS 2 5 D + 3 4 USB TX - R T RX + D - Port SP3051-04HTG V BUS RX - USB RX + GND C SP3051-04HTG T C Unused T Controller Unused V 75 75 75 BU75S RX - V BUS VCC R T D + USB VCC R T Port GND D - GND C T C T 10/100/1000 Ethernet Protection RJ45 1 2 3 Unused TX + Unused TX + 10/100/1000 TX - Ethernet PHY 6 1 5 2 TX - 4 3 RX + RX - SP3051-04HTG RX + Unused Unused RX - VCC VCC Life Support Note: Not Intended for Use in Life Support or Life Saving Applications GND The products shown herein are not designed for use in life sustaining or life saving *NOTE: 1000Mbps Ethernet, or 1GbE, will require 8 channels of protection (4 differential applications unless otherwise expressly indicated. pair) so the solution above should be replicated for the additional 2 differential pair. 2019 Littelfuse, Inc. 1 Specifications are subject to change without notice.
