Designed to replace multilayer varistors (MLVs) in portable applications where low operating voltage is vital, DIODES™ D3V3L1B2WS offers superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. D3V3L1B2WS is designed to protect sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD), lightning, electrical fast transients (EFT), and cable discharge events (CDE).


  • Provides ESD Protection per IEC 61000-4-2 Standard:
    • Air ±26kV, Contact ±26kV
  • 1 Channel of ESD Protection
  • Protects One Power or I/O Line
  • Peak Pulse Power: PPP = 90W at tp = 8/20μs
