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.
