ESD protection for in-vehicle bus lines are qualified to AEC-Q101
8 March 2023 
The PESD2CANFD36XX-QA devices are offered in a variety of packages and capacitance classes for commercial vehicle applications. The six AEC-Q101-qualified ESD protection devices protect bus lines in automotive in-vehicle networks , for example LIN, CAN, CAN-FD, FlexRay and SENT, from damage caused by ESD and other transients. The increase in data rates increase and electrification within vehicles means that the need for ESD protection is becoming ever more critical, says the company.
Lorries, trucks and commercial vehicles typically use 24V board nets, larger than the battery voltage found in cars and smaller vehicles. ESD protection devices with operating voltages typically above 32V are required to safeguard sensitive signal lines in 24V board nets. The ESD devices have been designed to have a maximum reverse standoff voltage of 36V and up to 22kV ESD protection. They also have a low clamping voltage of 48V VCL at IPP of 1.0A for robust in-vehicle networks.
The devices are available in SOT23 and SOT323 packages and three low capacitance classes (4.3, 6.0 and 10pF) for smooth communication between interfaces without impacting signal integrity.
