Low capacitance unidirectional ESD protection diodes

Low capacitance unidirectional double ElectroStatic Discharge (ESD) protection diodes in a very small Surface-Mounted Device (SMD) plastic package designed to protect up to two signal lines from the damage caused by ESD and other transients.


  • Unidirectional ESD protection of up to two lines
  • ESD protection up to 30 kV
  • Low diode capacitance: Cd = 34 pF
  • IEC 61000-4-2; level 4 (ESD)
  • Max. peak pulse power: PPP = 70 W
  • IEC 61000-4-5 (surge); IPP = 6.5 A
  • Low clamping voltage: VCL = 13 V
  • AEC-Q101 qualified
  • Ultra low leakage current

Target applications

  • Audio and video equipment
  • Communication systems
  • Computers and peripherals
  • Portable electronics
  • Cellular handsets and accessories
  • Subscriber Identity Module (SIM) card protection
