TVS Diode Arrays (SPA Diodes) Lightning Surge Protection- AQ4024 Series RoHS Pb GREEN AQ4024 Series 1.3pF, 7A Discrete TVS Diode Description The AQ4024 series integrates low capacitance steering diodes with one or two avalanche breakdown diodes for unidirectional or bidirectional protection, respectively, to protect against ESD and lightning induced surge events. These components can safely absorb up to 7A per IEC nd 61000-4-5 2 edition (t =8/20s) without performance p degradation and a minimum 30kV ESD per IEC 61000- 4-2 International Standard. The low loading capacitance and high surge capability make it ideal for protecting telecommunication ports such as xDSL and other high voltage, high speed legacy interfaces.
