Optimised to protect sensitive telecommunication ports against electrostatic discharge (ESD) and lightning-induced surge events, Littelfuse has introduced a series of AEC-Q101-qualified TVS diode arrays. SP4208 series TVS Diode Arrays (SPA Diodes) integrate low capacitance steering diodes with either one avalanche breakdown diode (for unidirectional protection) or two (for bidirectional protection).
They can safely absorb up to 30A of surge current and a minimum of ±30kV ESD without performance degradation. Their low loading capacitance (3.0pF) and high surge capability make them well-suited for protecting telecommunication ports such as Ethernet and other high-speed data interfaces.
Typical applications for SP4208 series TVS diode arrays include:
“The SP4208 series TVS diode arrays combine a standoff voltage of 8V with a low dynamic resistance, which supports those implementations of G.Fast that run at higher voltages,” said Tim Micun Business Development Manager, TVS diode arrays (SPA Diodes) at Littelfuse. “Their ‘flow-through’ design minimises signal distortion, reduces voltage overshoot, and allows for a simpler printed circuit design.”
SP4208 series TVS diode arrays offer these benefits:
