SM712-02HTG Product Details

Littelfuse SM712-02HTG Series TVS Diode Array is a 600W Asymmetrical TVS diode array 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 SM712-02HTG can absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard without performance degradation and safely disspate up to 19A of 8/20us induced surge current (IEC-61000-4-5) with very low clamping voltages.Learn More about Littelfuse TVS Diode Arrays SPA




  • 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
