General Purpose ESD Protection - AQxxC-1FTG SD-C Series Series AQxxC-1FTG Series RoHS Pb GREEN Description The bidirectional AQxxC series is designed to replace multilayer varistors (MLVs) in electronic equipment for low speed and DC applications. It will protect any sensitive equipment from damage due to electrostatic discharge (ESD) and other transient events. The AQxxC series can safely absorb repetitive ESD strikes at ±3kV (contact discharge, IEC 1--) without performance degradation and safely dissipate 3A (AQ5C) of /μs induced surge current (IEC 1--5) with very low clamping voltages. Pinout and Functional Block Diagram 1 Features ESD, IEC 1--, ±3kV contact, ±3kV air EFT, IEC 1--, A (5/5ns) Lightning, 3A (/ as defined in IEC 1--5 nd edition) AQ5C Low clamping voltage PPAP capable Low leakage current Small SOD33 package fits 5 footprints AEC-Q11 qualified Moisture Sensitivity Level(MSL -1) Halogen free, lead free and RoHS compliant Applications Switches / Buttons Test Equipment / Instrumentation Point-of-Sale Terminals Medical Equipment Notebooks / Desktops / Servers Computer Peripherals CAN Bus protection Automotive applications Life Support Note: Not Intended for Use in Life Support or Life Saving Applications The products shown herein are not designed for use in life sustaining or life saving applications unless otherwise expressly indicated.
