Littelfuse SM712 600W Asymmetrical TVS Diode Array
Littelfuse SM712 600W Asymmetrical TVS Diode Array is designed to protect RS-485 applications with asymmetrical working voltages (-7V to 12V) from damage due to electrostatic discharge (ESD), lightning-induced surges, and electrical fast transients (EFT). The SM712 absorbs repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standards without performance degradation. It safely dissipates up to 19A of 8/20us induced surge current (IEC-61000-4-5) with very low clamping voltages. Littelfuse SM712 600W Asymmetrical TVS Diode Array is AEC-Q101 qualified, lead free, and RoHS compliant.
