ST’s broad range of automotive-grade clamping diodes and filters meets all automotive standard requirements:
- IEC 61000-4-2 and ISO 10605 for ESD protection
- ISO 7637-3 for electrical disturbances from conduction and coupling
- ISO 16750 for environmental conditions and testing for electrical and electronic equipment
- AEC-Q101 and the most stringent international automotive quality requirements
It addresses all the protection sockets in automotive applications, from infotainment, navigation, communication, audio and video to battery charging systems, smart junction boxes, relays and power-lines, with:
- Transient voltage suppressors (TVS) to protect sensitive automotive circuits against overvoltage surges defined in ISO 7637-3, against electrostatic discharges according to IEC 61000-4-2 and ISO 10605
- EMI and common-mode filters (EMIF and ECMF series) to avoid electromagnetic coupling and radiation on high-speed buses in addition to protecting them from electrostatic discharges
Providing versatile ESD protection solutions for CAN, LIN and Flexray bus, ST’s automotive-grade ESDCAN protection devices combine the best trade-off on line capacitance, package dimension and quality of protection in a single range of devices.
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.
