LCDA05 through LCDA24 Low Capacitance TVS Diode Array For High-Speed Data Interfaces PROTECTION PRODUCTS Features Description The LCDA series of TVS arrays are designed to protect Transient protection for high-speed data lines to sensitive electronics from damage or latch-up due to IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) ESD and other voltage-induced transient events. Each IEC 61000-4-4 (EFT) 40A (5/50ns) device will protect two high-speed lines. They are IEC 61000-4-5 (lightning) (8/20s)* available with operating voltages of 5V, 12V, 15V and Protects two I/O lines 24V. They are bidirectional devices and may be used on Low capacitance for high-speed data lines lines where the signal polarities are above and below Working voltages: 5V, 12V, 15V and 24V ground. Low leakage current TVS diodes are solid-state devices designed specifically Low operating and clamping voltages for transient suppression. They offer desirable charac- Solid-state silicon avalanche technology teristics for board level protection including fast re- sponse time, low operating and clamping voltage and Mechanical Characteristics no device degradation. The LCDA series devices JEDEC SO-8 package feature low capacitance compensation diodes in series Molding compound flammability rating: UL 94V-0 with standard TVS diodes to provide an integrated, low Marking : Part Number, Date Code capacitance solution for use on high-speed interfaces. Packaging : Tape and Reel per EIA 481 The LCDA series devices may be used to meet the immunity requirements of IEC 61000-4-2, level 4.
