ST's automotive dataline ESD protection ICs are transient voltage suppressors or application-specific discrete devices that provide system level protection against surge pulses as defined in ISO 7637-2 and ESD surges according to IEC 61000-4-2 and ISO 10605.

ST's automotive dataline ESD protection ICs are manufactured using automotive-grade processes and qualified to AEC-Q101 for standard CANbus, LINbus, and FLEXray automotive interfaces.

Moreover, ST offers innovative, flexible package solutions for enhanced layout options.

Recognized worldwide for its leading-edge technology, ST's large portfolio of protection devices have passed all certifications, meeting or exceeding international protection standards for electrical hazards on electronics boards found in the demanding automotive, computer, consumer, industrial and telecom markets.

To help you find the best solution for your application, ST provides online ESD design tools such as the TVS smart selector.

ESD protection for CAN, CAN-FD and LIN interfaces

After a first generation housed in an SOT23-3L package, ST is now offering new devices that ensure robust ESD protection for automotive CAN bus lines in the SOT323-3L package – 40% smaller – with a line capacitance of 3.5 pF (vs 30 pF), and a voltage range from 24 to 37 V. All ST’s ESDCAN devices work up to 175 °C and sustain up to 30 kV ISO 10605 as well as ISO 7637 surges. The series extension includes 36 V (VRM) products – ESDCAN05-2BWY and ESDCAN06-2BWY – that are compatible with 24 V systems used in trucks.

In addition, ST offers ESDLIN devices designed and intended to protect automotive LIN bus lines against electrostatic discharge (ESD) and transient voltages.
