The UAD8C05L01 includes back -to-back TVS 
diodes fabricated in a proprietary silicon 
avalanche technology to provide protection for
electronic equipment that may experience 
destructive electrostatic
discharge (ESD). These robust diodes can safely 
absorb repetitive ESD strikes up to the maximum 
level specified in the IEC61000 -4-2 international 
standard without performance degradation.
The back-to-back configuration provides 
symmetrical ESD protection for data lines when AC 
signals are present.
