The SM712 TVS Diode Array is designed to protect RS-485
applications with asymmetrical working voltages (-7V to
12V) from damage due to electrostatic discharge (ESD),
electrical fast transients (EFT), and lightning induced surges.
The SM712 can absorb repetitive ESD strikes above the
maximum level specified in the IEC 61000-4-2 international
standard without performance degradation and safely
dissipate up to 19A of 8/20us induced surge current (IEC61000-4-5 2nd edition) with very low clamping voltages.
