Littelfuse SR05
The SR05 consists of four, low capacitance steering diodes and a low voltage TVS diode that provide protection against ESD and lightning surge events. Each channel or I/O pin can safely absorb up to 25A (tp=8/20μs) and repetitive ESD strikes above the maximum level (Level 4) specified in the IEC 61000-4-2 international standard without performance degradation. The low loading capacitance makes it ideal for protecting high-speed telecommunication data lines.DESCRIPTION
