TVS Diode Arrays (SPA® Diodes) Lightning Surge Protection- SP4021 Series SP4021 Series 2.5pF, 25A Discrete TVS Diode RoHS Pb GREEN The SP4021 devices 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 devices can safely absorb up to 25A per IEC61000-4-5 (tp=8/20μs) without performance degradation and a minimum ±30kV ESD per IEC61000-4-2 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.
