Automotive dataline ESD protection

ST's automotive dataline ESD protection devices are monolithic transient voltage suppressors or application-specific discrete devices that guard against surges defined in ISO 7637-2 and against ESD according to IEC 61000-4-2 and ISO 10605. They protect components connected to data and transmission lines in applications such as automotive infotainment, navigation, communication and audio and video systems.

They offer:

  • Standard CANbus, LINbus, and FLEXray automotive interfaces
  • Flexibility in packaging and integration options
  • ST’s advanced expertise in ESD protection for communication systems such as audio/visual and infotainment applications

Produced using automotive-grade processes and qualified to AEC-Q101, they are identified with the Y extension in the part number for the automotive version of the given protection device.

Low-capacitance, robust ESD protection for automotive CAN bus lines

The ESDCAN02-2BWY and ESDCAN03-2BWY devices are designed to protect automotive communication buses such as CAN, CAN-FD, LIN, FlexRay, MOST, SENT… AEC-Q101 qualified, they feature up to 30 kV robustness (ISO 10605) and a low line capacitance (< 5 pF). The capacitance matching between lines does not exceed a best in class 0.1 pF for skew reduction and compliance with the fastest interface standards. Both these devices – key for design and time-to-market optimization – are housed in a SOT323-3L package, allowing a 46% PCB space as well as cost savings versus SOT23 package solutions available on the market.
