SLVU2.8-8 EPD TVS Diode Array For ESD and Latch-Up Protection PRELIMINARY PROTECTION PRODUCTS Features Description The SLV series of transient voltage suppressors are 600 Watts peak pulse power (tp = 8/20s) 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 (tp = 5/50ns) lightning and other induced voltage surges. IEC 61000-4-5 (Lightning) 24A (tp = 8/20s) Protects four line pairs (eight 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- High peak pulse current (30A, 8/20s) avalanche diode processes. The SLVU2.8-8 features Low leakage current integrated low capacitance compensation diodes that Low operating and clamping voltages reduce the maximum capacitance to 8pF per line. Solid-state EPD TVS process technology This, combined with low leakage current, means signal integrity is preserved in high-speed applications such Mechanical Characteristics as 10/100 Ethernet. JEDEC SO-8 package The SLVU2.8-8 is in an SO-8 package and may be used Molding compound flammability rating: UL 94V-0 to protect four high-speed line pairs. The layout of the Marking : Part number, date code, logo device minimizes trace inductance and reduces voltage Packaging : Tape and Reel per EIA 481 overshoot associated with ESD events. The low clamping voltage of the SLVU2.8-8 minimizes the Applications stress on the protected IC. 10/100 Ethernet The SLV series TVS diodes will meet the surge require- WAN/LAN Equipment ments of IEC 61000-4-2 (ESD), IEC61000-4-5 (Light- Switching Systems ning), and ETSI ETS 300 386.
