CAN ESD protection devices compliant with CAN-FD, LIN, FlexRay, MOST, and SENT

STMicroelectronics has introduced two new devices for protection of CAN (Controller Area Network) bus lines against electrostatic discharges and other transients and market-unique compliance with all key automotive interfaces. ST says it has produced the world’s first CAN protection devices to comply with all major interfaces, including CAN-FD, LIN, FlexRay, MOST, and SENT.

The ESDCAN02-2BWY and ESDCAN03-2BWY are automotive-grade dual-line Transil devices feature ultra-low capacitance of 3.5pF and 24V minimum stand-off voltage.

Key technical features of the new devices include:
Low capacitance (3.5 pF, max), leading to a BOM reduction and design simplification for high bit-rates.
An SOT323 package, smaller than all existing solutions, that helps minimize PCB area.
The ESDCAN02-2BWY with 28V minimum VBR meets automotive reverse battery requirements.
The ESDCAN03-2BWY’s very low VCL of 35V max is the best clamping voltage on the market.
Both devices are ISO10605-compliant, managing ESD surges up to the maximum ±30kV covered by the standard, ensuring robustness in the application.

Housed in an ultra-compact SOT323-3L package, the new devices are available in volume at a price of US$0.078 in quantities of 100 units.
