ESD PROTECTION FOR CAN BUS SYSTEMS

Program Description:

Controller Area Network (CAN) bus systems are widely used in automotive, industrial, and automation applications, offering robust communication in harsh environments. However, these systems are vulnerable to electrostatic discharge (ESD) events, which can cause transient disturbances, degrade signal integrity, and even lead to permanent damage of transceivers. This seminar will explore how to effectively protect CAN bus lines against ESD events using dedicated protection diodes, focusing on practical design considerations, component selection, and PCB layout best practices. Key Topics Covered: • Understanding ESD Threats in CAN networks – real-world sources and failure mechanisms • Control Area network – Standards and Applications • Selection Criteria – how to choose the right ESD protection diode based on voltage, capacitance, clamping performance, and package size • Layout Guidelines – routing and grounding tips for maximum protection efficiency • Case Studies – examples of ESD protection for CAN, LIN, and related automotive buses
