The ESDCAN02-2BWY and ESDCAN03-2BWY are automotive-grade dual-line Transil devices that leverage ST’s leadership in transient protection devices and its understanding of the automotive market. The unique combination of parameters, including an ultra-low capacitance of 3.5pF and 24V minimum stand-off voltage, has produced the world’s first CAN protection devices to comply with all major interfaces, including CAN-FD, LIN, FlexRay, MOST and SENT. The low capacitance enables a reduction in BOM and design simplification for high bit-rates.
The ESDCAN02-2BWY features a minimum breakdown voltage of 28V, which meets automotive reverse battery requirements. The ESDCAN03-2BWY’s very low maximum clamping voltage of 35V is claimed to be 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. Both devices are supplied in an ultra-compact SOT323-3L package which helps minimise PCB area.
The devices are available for $0.078 in 100 unit quantities.
