SLVU2.8-4 EPD TVS Diode Array For ESD and Latch-Up Protection PRELIMINARY PROTECTION PRODUCTS Features Description The SLV series of transient voltage suppressors are 400 Watts peak pulse power (t = 8/20s) p designed to protect low voltage, state-of-the-art CMOS Transient protection for high speed data lines to semiconductors from transients caused by electro- IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) static discharge (ESD), cable discharge events (CDE), IEC 61000-4-4 (EFT) 40A (5/50ns) lightning and other induced voltage surges. IEC 61000-4-5 (Lightning) 24A (8/20s) Protects two line pairs (four lines) The devices are constructed using Semtechs propri- etary EPD process technology. The EPD process pro- Comprehensive pin out for easy board layout vides low standoff voltages with significant reductions Low capacitance in leakage currents and capacitance over silicon- Low leakage current avalanche diode processes. The SLVU2.8-4 features Low operating and clamping voltages integrated low capacitance compensation diodes that Solid-state EPD TVS process technology reduce the typical capacitance to 5pF per line. This, combined with low leakage current, means signal Mechanical Characteristics integrity is preserved in high-speed applications such JEDEC SO-8 package as 10/100 Ethernet. Molding compound flammability rating: UL 94V-0 The SLVU2.8-4 is in an SO-8 package and may be used Marking : Part number, date code, logo to protect two high-speed line pairs. The flow-thru Packaging : Tape and Reel design minimizes trace inductance and reduces voltage overshoot associated with ESD events. The low Applications clamping voltage of the SLVU2.8-4 minimizes the 10/100 Ethernet stress on the protected IC.
