The S23LC series is a family of high energy, low capacitance EOS protectors packaged in the industry standard SOT-23 outline. The most prevalent voltage types (3.3, 5, 12, 15 and 24V) used in logic level and IC power rail circuitry are available making them ideal for EOS protection of VBus and user interface applications. The devices have a high peak power capability of 300W (8x20μs) and a tight clamping ratio (VC/VRWM typical < 2). The combination of high peak power capability, precise clamping and low idle current make these devices far superior to MOV / MLV type protectors in data line, power rail and user interface applications.
Features
• High peak power capability of 300W (8x20μs)

• Broad range of working voltages (3.3V to 24V)
• Low idle / standby current for energy efficiency (< 1μA for 12 thru 24V devices)
• Tight clamping ratio (typically<2) for precise protection
• Industry standard SOT-23 package
Applications
• RS-232 and RS-422 data lines
• User interface
