LCDA12C-1 Datasheet | SEMTECH

Description The LCDAxx C-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 mon (line-to-ground) mode or one line pair in metallic (Line-to-line) mode. They are low capacitance (< 15p F) making them suitable for use on high-speed tele and data interfaces without signal degradation. The configuration of the LCDAxx C-1 has been optimized for easy layout on high density boards. The small SOT143 package minimizes required board space. These devices will handle up to 20 Amps for an 8/20µs lightning impulse. The low inductance construction minimizes voltage overshoot during high current surges. The LCDAxx C-1 may be used to protect ADSL interfaces, multi-protocol serial transceivers, portable electronics, and wireless systems.
