We are interested in protecting the communication data lines (CAN / RS485 communication lines) connected to an Automotive grade industrial connector. The pins connecting this connector are driven by a 3.3V typical operating condition.
1. What are the critical criteria for protecting my device from ESD?
2. How Important is the capacitance of the TVS diode/ESD?
3. Should we select a TVS diode depending on its Rated Working Peak Voltage and clamping voltage?
4. ESD contact level - (air and contact)
5. What is the role of Peak Impulse Current on selecting a ESD/ TVS diode?
6. Criteria for ESD on a power line ?
