Description
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.
