PROTECTION PRODUCTS PRELIMINARY 1 www.semtech.com PROTECTION PRODUCTS LCDA12C-1 and LCDA15C-1 Low Capacitance TVS Diode Array Description Features Circuit Diagram Schematic & PIN Configuration Revision 01/15/03 The LCDAxxC-1 is a low capacitance transient voltage suppressor (TVS) diode array. It is designed to protect sensitive CMOS ICs from the damaging effects of ESD and lightning. Each device will protect one line in common (line-to-ground) mode or one line pair in metallic (Line-to-line) mode. They are low capacitance (< 15pF) making them suitable for use on high-speed telecom and datacom interfaces without signal degra- dation. The configuration of the LCDAxxC-1 has been optimized for easy layout on high density boards. The small SOT-143 package minimizes required board space. These devices will handle up to 20 Amps for an 8/20µs lightning impulse. The low inductance con- struction minimizes voltage overshoot during high current surges. The LCDAxxC-1 may be used to protect ADSL inter- faces, multi-protocol serial transceivers, portable electronics, and wireless systems.
