1 TVS Diode Arrays (SPA Diodes) Lightning Surge Protection- AQ4020 SP4020 Series AQ4020 Series 2.5pF, 30A Discrete TVS Diode RoHS Pb GREEN Description The AQ4020 components integrate low capacitance steering diodes with one or two zener diodes for unidirectional or bidirectional protection, respectively, to protect against ESD and lightning induced surge events. These components can safely absorb up to 30A per IEC nd edition (t p =8/20μs) without performance degradation and a minimum ±30kV ESD per IEC International Standard. The low loading capacitance and high surge capability make it ideal for protecting telecommunication ports such as Ethernet and other high speed data interfaces. Pinout Features Pin 1 ESD, IEC , ±30kV contact, ±30kV air EFT, IEC , 40A (5/50ns) Unidirectional and bidirectional configuration Small SOD323 package fits 0805 footprints Lightning, IEC nd edition, 30A (t P =8/20μs) Low capacitance of 2.5pF (@ V R =0V) Low leakage current of 0.1μA at 3.3V AEC-Q101 Qualified Moisture Sensitivity Level(MSL -1) Halogen free, lead free and RoHS compliant Pin 2 Functional Block Diagram Applications /100/1000 Ethernet Instrumentation T1/E1/T3/E3 Medical Equipment USB 1.1/2.0 CAN Bus protection Power Ports Automotive applications Computers and Peripherals 2 2 Unidirectional Bidirectional AQ FTG SP FTG AQ FTG-C SP FTG-C 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.
