  2017/09/06    High Energy Multi-line EOS Protection Arrays LCDA03 thru LCDA24

The LCDA03 thru LCDA24 series of devices is a family of bi-directional, high energy, multi-line EoS (electrical over-stress) arrays available in the industry standard SO-8 package outline.  The LCDA series of devices can simultaneously protect two high speed data lines of varying polarity from ESD or other forms of EoS.  The devices are available with working voltage ratings that reflect the most commonly used design values of 3.3, 5.0, 12.0, 15.0 and 24.0 volts. The LCDA devices have a much lower idle current (efficiency) than MLVs, have a much tighter clamping ratio (VC/VRWM) for more precise protection and have no inherent “wear-out” mechanism as do MLVs that are subjected to multiple surge events.

 

Features

 High peak pulse power capability of 300W (8x20μs)

 Protects two high speed I/O lines of varying polarity

 Very low capacitance (5pF max) enables use on high speed data lines

 Bidirectional protection

 Broad range of working voltages (3.3V to 24V)

 Low idle / standby current (typically <1μA) for energy efficiency

 Tight clamping ratio (VC/VRWM) typically less than 2 for precise protection

 

Applications

I/O ports and data lines

User interface: switches, buttons, keypads

Integrated Circuit (IC) Vbus power rail

Power and accessory ports
