General Purpose ESD Protection - SM712

RoHS

GREEN

SM712 Series 600W Asymmetrical TVS Diode Array

Description

The SM712TVS 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 (IEC-

61000-4-5 2nd edition) with very low clamping voltages.
