Littelfuse SP712 640W Asymmetrical TVS Diode Array

Littelfuse SP712 TVS Diode Array is designed to protect RS-485 applications with asymmetrical working voltages (-7V to 12V). The 640W diode offers protection from damage due to electrostatic discharge (ESD), electrical fast transients (EFT), and lightning-induced surges. The diode can absorb repetitive ESD strikes above the maximum level specified in the IEC 61000-4-2 international standard without performance degradation. The Littelfuse SP712 TVS Diode Array can safely dissipate up to 20A of 8/20μs induced surge current (IEC 61000-4-5) with very low clamping voltages and is AEC-Q101 qualified.
