ESDSR05AP
Description
The ESDSR05AP 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 5A (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 capacitance of the steering diode allows
the designer to protect high speed data applications .
