The SP4021-01FTG-C components integrate 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 25A per IEC 61000-4-5 (tp=8/20μs) without performance 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 Ethernet and other high speed data interfaces. IEC 61000-4-2 ESD protection: ±30kV by contact and ±30 kV through air IEC 61000-4-4 EFT protection: 40 A (5/50 ns) Lightning, 25 A (8/20 as defined in IEC 61000-4-5 2nd edition) Low capacitance of 2.5pF (@ VR=0V) Low leakage current Unidirectional and Bidirectional configuration Small SOD323 package fits 0805 footprints Moisture Sensitivity Level (MSL-1) AEC-Q101 Qualified Lead-free, halogen-free, and RoHS compliant
