  • TVS protection Diodes

    A bidirectional TVS diode can protect the CAN transceiver bus pins for short overvoltage events. TVS diodes offer the most effective protection against ESD, burst EFT, and surge transients because of short response times of a few picoseconds and power ratings up to several kilowatts.

  • Common mode choke

    Common-mode chokes are used in automotive CAN networks to enhance electromagnetic compatibility (EMC) by filtering out high-frequency noise from the ECU through the CAN transceiver. They also improve the transceiver's immunity to electromagnetic disturbances on the bus.

  • Split termination resistor

    The split termination uses two resistors equal to half the cable’s characteristic impedance (typically 60Ω each) with a capacitor between the common-mode point and ground. While it uses more components, it creates a low-pass filter for common-mode noise, improving electromagnetic emissions. The RC components form an RC low-pass filter with a specific corner frequency.
