Littelfuse introduced a series of AEC-Q101-qualified TVS Diode Arrays optimized to protect sensitive telecommunication ports against electrostatic discharge (ESD) and lightning-induced surge events. 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.

“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 minimizes signal distortion, reduces voltage overshoot, and allows for a simpler printed circuit design.”

SP4208 Series TVS Diode Arrays are available in SOD323 packaging in tape and reel format in quantities of 3,000. Sample requests may be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
