The DIODES™ D2V8F4U8MR of transient voltage suppressors are designed to protect low voltage. This has been specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), and FET (electrical fast transients).


  • Protects Two Line Pairs (Four Lines)
  • Low Capacitance < 3pF for High-Speed Interfaces
  • Low Operating and Clamping Voltages
  • IEC 61000-4-2, Level 4 (ESD), <= ±15kV (Air); <= ±8kV (Contact)
  • IEC 61000-4-5, Level 2 (Lightning), 24A (8/20µs)
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
  • Halogen and Antimony Free. “Green” Device (Note 3)
