SM712-02HTG - SM712 Series

  1. Littelfuse SM712 Series TVS Diode Array (SPA® Diodes) 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. It 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 8/20μs surge current (IEC-61000-4-5) with very low clamping voltages.

Features:


  • Robust surge and enhanced ESD protection: ESD, IEC61000-4-2: ±30kV (contact); EFT, IEC61000-4-2: 50A; Lightning, IEC61000-4-5: 19A; Peak pulse power: 600W
  • Asymmetrical standoff voltage matches RS-485 transceiver profile
  • Low dynamic resistance (0.5Ω TYP) offers superb clamping performance
  • Minimal capacitive loading of 75pF (MAX)
  • AEC-Q101 qualified

Applications:


  • RS-485
  • Fieldbus
  • Modbus
  • Profibus
  • DMX512
  • Security Systems
  • Automated Teller Machines (ATMs)
  • Automation Equipment
  • Communication Equipment
