Vbus ESD 防护
DC buses and voltage buses on data links are found virtually everywhere in electronics based sub-systems. These buses are often vulnerable discharge point and path for ESD entry into an electronics system. To safeguard these interfaces and provide adequate protection against overvoltage threats, Semtech has several platforms of industry leading transient voltage suppressors. The low-clamping voltage and small form factors makes these TVS solutions ideal for safeguard DC lines and data line voltage buses.

在现代电信和工业自动化系统中，设备经常需要部署在恶劣环境中，因此容易遭受电压瞬变的冲击，这些瞬变可能源于电机切换、电源线路波动、间接雷击、静电积聚或人为操作等因素Electrostatic Discharge (ESD）） events. These transients pose significant risks, ranging from data corruption to catastrophic system failures, leading to costly downtime and repairs. As industrial and telecom systems become increasingly interconnected, safeguarding sensitive electronics from ESD and other transient voltage events is crucial. Transient Voltage Suppression (TVS) diodes provide a robust first line of defense by rapidly diverting excess energy to ground, as illustrated in Figure 1, with sub-nanosecond response times to clamp voltage spikes and protect critical components.

The automobile industry, a hotbed of innovation since the first motor vehicles hit the roads, has significantly evolved in recent years. This evolution, particularly in automotive Ethernet, is crucial for the industry's progress. Today's cars boasta plethora of features, including autonomous and semi-autonomous driving capabilities, automatic emergency braking, lane departure warning, Omni-View systems (surround-view system, Bird's eye system, etc.) thateliminateblind spots, and a highly interactive and intuitive infotainment system. These innovations rely on a network of advanced cameras and sensors like radar, lidar, or image sensors to collect comprehensive information about the vehicle's physical environment. This data is then seamlessly conveyed to the driver through the dashboard display, alleviating their workload across various driving scenarios.
