To ensure correct operation throughout a vehicle's lifetime in harsh environments, automotive applications must be protected against damaging voltage transients like lightning and electrostatic discharges (ESD) in compliance with ISO standards.
Applications
Why should you use ESD protection in automotive applications?
If there is no protection, ICs generally rated according to Human Body Model (HBM) or Charged Device Model (CDM) standards for their ESD capability, cannot survive the high currents and voltages specified in ISO standards.
For instance, when a circuit becomes damaged, warning lamps will appear in the dashboard and the driver will feel unsafe and will have a bad image of the vehicle’s quality. So, you need reliable and efficient protection against rated automotive surges.
Types of automotive ESD protection
ST's automotive data line ESD protection devices include transient voltage suppressors (TVS) and application-specific discrete devices that provide system level protection against ESD surges according to standard IEC 61000-4-2. ESD protection devices are manufactured using automotive-grade processes and qualified to AEC-Q101 standards. As such, they can address all automotive applications and domains including advanced driver-assistance systems (ADAS), vehicle-to-everything (V2X), CAN-FD, SerDes (serializer/deserializer), and Ethernet Base-T standards to name just a few. Moreover, ST offers innovative, miniature wettable flank DFN packages to ease Automatic Optical Inspection (AOI).
