Littelfuse integrates rail-to-rail diodes with an additional Zener diode built in to help protect I/O pins from ESD and high surge events. Very low loading capacitance makes it ideal for protecting high-speed signals in Ethernet and Firewire type of applications. This robust device can safely absorb 10 A surge current per IEC 61000-4-5 (t_P=8/20 μs) without performance degradation and a minimum ±30 kV ESD per IEC 61000-4-2. Their very low loading capacitance also makes them ideal for protecting high-speed signal pins.
