TVS Diode Arrays (SPA(R) Diodes) Lightning Surge Protection - SLVU2.8-4 Series SLVU2.8-4 Series 2.8V 40A TVS Array RoHS Pb GREEN Description The SLVU2.8-4 was designed to protect low voltage, CMOS devices from ESD and lightning induced transients. There is a compensating diode in series with each low voltage TVS to present a low loading capacitance to the line being protected. These robust structures can safely absorb repetitive ESD strikes at 30kV (contact discharge) per IEC 61000-4-2 standard and each structure can safely dissipate up to 40A (IEC 61000-4-5 2nd edition, tP=8/20s) with very low clamping voltages. Features * EFT, IEC 61000-4-4, 40A (5/50ns) * SOIC-8 (JEDEC MO-012) pin configuration allows for simple flow-through layout * Lightning, IEC 61000-4-5 2nd edition, 40A (8/20s) * RoHS Compliant and Lead Free * Low capacitance of 2pF per line * Moisture Sensitivity Level (MSL-1) * ESD, IEC 61000-4-2, 30kV contact, 30kV air Pinout 4 3 2 1 * Low leakage current of 1A (MAX) at 2.8V 5 6 7 8 Applications Functional Block Diagram Pin 1.3 Pin 6.8 * 10/100/1000 Ethernet * Analog Inputs * WAN/LAN Equipment * Base Stations * Switching Systems * Desktops, Servers, and Notebooks Application Example Pin 2.4 Pin 5.7 Ethernet PHY Tx+ TxRx+ Rx- RJ-45 Connector J1 Additional Information SLVU2.8-4 Device is shown as transparent for actual footprint Resources Samples J8 Case GND (c) 2017 Littelfuse, Inc.
