ESD protection for automotive CAN-FD (CAN Flexible Data Rate)

CAN-FD ESD protection solutions for Automotive applications

TAs data payload in vehicles increases, high-speed data transmission becomes essential and new protocols find their way into in-vehicle networks. The CAN protocol is famous but limited to 1Mbit/s whereas CAN-FD (Flexible Data) covers speeds up to 5 Mbit/s. 2 Mbit/s is the typical implementation limit suitable for many applications that do not require higher data rates.
