SR05 Series TVS Diodes Array - High Speed

SR05 Series TVS Diodes Array - High Speed

Littelfuse, Inc. has introduced the SR05 series TVS diode array - SPA diodes, designed to protect telecommunication and industrial equipment against electrostatic discharge (ESD) and lightning-induced surge events. Each channel or I/O pin can safely absorb up to 25 A and repeated ESD strikes without performance degradation. Modern chipsets are highly susceptible to damage because of their extremely-thin oxide layers and shallow transistor junctions. SR05 series devices’ extremely-low dynamic resistance and clamping voltage levels ensure their ability to protect today’s small geometry chipsets from damaging transients. With very low capacitance from each I/O to ground, these devices provide robust protection maintaining signal integrity, preventing data loss during transmission.

Typical applications of SR05 series TVS diode arrays include protecting high-speed interfaces such as T1/E1/T3/E3 lines, Ethernet 10BaseT lines, WAN/LAN equipment, ISDN S/T interfaces, video lines, microcontroller inputs, USB1.1 ports, and more. SPA Family of TVS Diode Arrays
