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.

SOT23 packaged automotive dataline ESD protection devices

The SOT23 package, that is so widely used for many device types in the automotive electronics industry, is now used to house ST's range of automotive dataline ESD protection devices, thus simplifying the PCB assembly process. The package is supplied in 3-, 5- and 6-lead versions to house the 2-, 4- and 5-line protection devices. AEC-Q101-qualified, with PPAP available upon request, ST’s SOT23 automotive-grade products all comply with ISO 7637-2.
