TVS diode arrays protect sensitive telecom ports from ESD and lightning-induced surges

Littelfuse has introduced a series of AEC-Q101-qualified TVS Diode Arrays optimised to protect sensitive telecommunication ports against ESD and lightning-induced surge events. The 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 safely absorb up to 30A of surge current and a minimum of ±30kV ESD without performance degradation. Their low loading capacitance (3pF) and high surge capability make them ideal for protecting telecommunication ports such as Ethernet and other high-speed data interfaces. “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.”
