General Purpose ESD Protection - AQxxC-1FTG Series AQxxC-1FTG Series 5W Bidirectional TVS Diode RoHS Pb GREEN Description The bidirectional AQxxC-1FTG 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-1FTG series can safely absorb repetitive ESD strikes of ±3 kv (contact and air discharge as defined in IEC 1--) without any performance degradation. Additionally, the AQ5C can safely conduct a 3A / surge event as defined in IEC 1--5 nd Edition. 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) for the 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.
