CAN bus ESD protection diode

ElectroStatic Discharge (ESD) protection diode in a very small SOT323 (SC-70 ) Surface-Mounted Device (SMD) plastic package designed to protect two automotive Controller Area Network (CAN) bus lines from the damage caused by ESD and other transients.


  • One very small SOT323 package to protect two CAN bus lines
  • Low clamping voltage VCL = 35 V at IPP = 1 A
  • Typical diode capacitance matching ΔCd/Cd = 0.1 %
  • ESD protection up to 23 kV; IEC 61000-4-2, level 4
  • IEC 61000-4-5 (surge); IPPM = 3 A at tp = 8/20 μs
  • AEC-Q101 qualified

Target applications

  • CAN bus protection
  • Automotive applications
