In-Vehicle Network (CAN / LIN / FlexRay) protection

The car is an extremely interconnected system, with over 100 ECUs all attempting to communicate with other systems in the car. To handle relatively low-data rate automotive specific traffic, three dedicated bus systems are used - CAN, LIN and FlexRay. Offering increased system robustness, our IVN bus line protection solutions are well suited to automotive bus protection without impeding signal integrity in this electrically noisy environment.

Design considerations

  • High ESD robustness up to 30 kV and high surge currents up to 3.5 A (8/20µs)
  • Excellent ESD clamping behavior
  • Operate at a low capacitance avoiding any unwanted circuit disturbances
  • Asymmetrical internal diode configuration, ensures optimized electromagnetic immunity
