Automotive ESD protection devices for CAN & LIN bus

esdcan

The ESDCAN series improves the quality of protection of the high-speed CAN and LIN transceivers without affecting the capacitance budget and reduces PCB size by 400% compared to conventional solutions.

The increased use of electronics in cars deeply modifies the E/E architecture with high-density boards concentrating tens of high-speed CAN or CAN-FD links, requiring highly integrated protection solutions. ST offers a wide range of AEC-Q101 CAN protection devices for passenger cars (12 V batteries) or commercial vehicles (24 V batteries) covering fault-tolerant CAN, CAN-FD, LIN and even FlexRay communication protocols.

Key features

  • Dual-line ESD and EOS protection
  • Bidirectional devices
  • Maximum pulse current: 5.5 A (8/20 μs)
  • Stand-off voltage: from 24 V up to 36 V
  • Low leakage current: 100 nA (max.)
  • Compliant with:
    • ISO 7637-3a and 3b
    • ISO 10605 / IEC 61000-4-2: up to 30 kV air and contact
    • ISO 16750-2
    • AEC-Q101

Benefits

  • ESD and EOS plug-and-play protection solutions for CAN transceivers already approved by various car makers
  • Enables high-density PCBs thanks to tiny, compact packages (SOT323-3L, QFN-3L, and DFN1110)
  • Design and layout flexibility with wide range of products with low capacitance
  • Covers most mission profiles with reliability tests performed at maximum TJ =175°C for CAN-FD, Flexray and various voltages to fit car and truck requirements.
