TVS Diode Array (SPA Diodes) Lightning Surge Protection- SP4021 Series RoHS GREEN Pb SP4021 Series 2.5pF, 25A Discrete TVS Diode Description The SP4021 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=8/20s) 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.
