Automotive ESD protection

To ensure correct operation throughout a vehicle's lifetime in harsh environments, disturbances encountered in automotive applications must be modelized in compliance with ISO standards.

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 and the car breaks down, in the best case, the car stops; in the worst case the car will not stop if the issue affects the braking system. So, you need a reliable and efficient protection against rated automotive surges.

Compliant with ISO 10605 specifications, ST's automotive dataline ESD protection devices include transient voltage suppressors (TVS) or application-specific discrete devices that provide system level protection against ESD surges according to standard IEC 61000-4-2.

ESD protection ICs are manufactured using automotive-grade processes and qualified to AEC-Q101 standards for automotive interfaces for many applications including advanced driver-assistance systems (ADAS), vehicle-to-everything (V2X), Global Navigation Satellite System (GNSS), SerDes (serializer/deserializer), and Ethernet Base-T standards to name just a few. Moreover, ST offers innovative, flexible wettable flank package solutions for enhanced layout options.
