LCDA15C-8 Semtech

LCDA12C-8 and LCDA15C-8 Low Capacitance TVS Diode Array For Multi-mode Transceiver Protection PROTECTION PRODUCTS Features Description The LCDAxxC-8 has been specifically designed to Transient protection for high-speed data lines to protect sensitive components which are connected to IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) data and transmission lines from over voltages caused IEC 61000-4-4 (EFT) 40A (5/50ns) by electrostatic discharge (ESD), electrical fast tran- IEC 61000-4-5 (Lightning) 0.5kV, 12A (8/20s) sients (EFT), and lightning. Protects eight I/O lines The low capacitance array configuration of the Low capacitance for high-speed interfaces LCDAxxC-8 allows the user to protect eight high-speed High surge capability data or I/O lines. They may be used on systems Low clamping voltage operating from 5 to 15 Volts. The high surge capability Solid-state silicon avalanche technology (500W, tp=8/20s) makes the LCDAxxC-8 suitable for telecommunications systems operating in harsh tran- Mechanical Characteristics sient environments. The low inductance construction JEDEC SO-16 package minimizes voltage overshoot during high current Molding compound flammability rating: UL 94V-0 surges. Marking : Part number, date code, logo The features of the LCDAxxC-8 are ideal for protecting Packaging : Tape and Reel per EIA 481 multi-protocol transceivers in WAN applications such as Frame Relay systems, routers, and switches.
