LCDA24C-1 Low Capacitance TVS Array PRELIMINARY PROTECTION PRODUCTSPROTECTION PRODUCTS Features Description The LCDA24C-1 is a low capacitance transient voltage Transient protection to high-speed data lines suppressor (TVS) diode array. It is designed to protect IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) sensitive CMOS ICs from the damaging effects of ESD IEC 61000-4-4 (EFT) 40A (5/50ns) and lightning. Each device will protect one line in IEC 61000-4-5 (Lightning) 0.5kV, 10A (8/20s) common (line-to-ground) mode or one line pair in Configuration optimized for easy board layout metallic (Line-to-line) mode. They are low capacitance Protects one line pair (< 15pF) making them suitable for use on high-speed Low capacitance (<10pF) for high-speed interfaces telecom and datacom interfaces without signal degra- Low clamping voltage dation.
