Automotive protection devices

ST’s automotive-grade protection device series meets all standard needs for automotive including:

  • ESD protection
  • Load-dump protection
  • Power-rail transient voltage suppressor (TVS) protection

As such, ST’s TVS clamping diodes, or Transil™, are designed to protect sensitive automotive circuits against overvoltage surges defined in ISO 7637-2 and against electrostatic discharges according to IEC 61000-4-2 and ISO 10605.

The broad range of devices addresses all the protection sockets in automotive applications, from infotainment, navigation, communication, audio and video to battery charging systems, smart junction boxes, and relay and power-line protection.

Standard automotive bus interfaces are supported to meet applications requiring CANbus, LINbus, and FLEXray.

ESDCAN01-2BLY keeps clamping voltage below 35 V

ST’s new ESD protection diode, the ESDCAN01-2BLY, is designed for circuit protection of automotive Controller Area Network (CAN) bus lines. It provides ESD circuit protection of up to 30 kV (ISO 10605) and overvoltage protection against other automotive electrical surges such as ISO 7637-3 pulse 3a/3b. Rated at 24 V stand-off voltage, it maintains the maximum clamping voltage below 35 V when subjected to ISO 7637-3 pulse 3a/3b. Housed in the SOT-23 package, it features a 230-watt peak pulse power even at 120 °C for protection in tough environments. Get to know more about the ESDCAN01-2BLY features and capabilities in its e-presentation.
