Diode for CAN Bus and Automotive Circuit Protection

Protek introduced a new circuit protection diode to shield CAN Bus and other automotive subsystem designs from electrostatic discharge and other electrical fast transient damage. The ESD protection level is rated at > 25 kilovolts. The PESD2402 is designed to protect two signal data lines from impairment arising from ESD and other applied transients. The diode operates at 24V with a low capacitance rating per line and is available in a SOT23 package configuration. The device is compliant to IEC 61000-4-2 and IEC 61000-4-4 circuit protection requirements which can protect downstream circuitry.


  • Compatible with IEC 61000-4-2 (ESD): Air ±15kV, Contact ±8kV
  • Compatible with IEC61000-4-4 (EFT)
  • 100 Watts Peak Pulse Power per Line(tp = 8/20µs)
  • Two Lines of Protection
  • ESD Protection > 25 kilovolts
  • Low Clamping Voltage
  • Low Capacitance
  • Low Leakage Current
  • RoHS Compliant
  • Reach Compliant
