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
