General Purpose ESD Protection - SM712
SM712 Series 600W Asymmetrical TVS Diode Array
RoHS Pb GREEN
Description
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 IEC61000-4-2 international
standard without performance degradation and safely
dissipate up to 19A of 8/20us induced surge current (IEC-
61000-4-5) with very low clamping voltages.
