USB ESD Protection
USB4 and USB 3.2 are quickly emerging as key data buses across a wide host of electronics equipment whereas USB 2.0 interfaces are prevalent across consumer, industrial, telecom, and communications equipment. These high-speed data ports are extremely vulnerable and sensitive to damage and latch-up from electrostatic discharge (ESD), electrical fast transients and cable discharge threats. Semtech provides industry leading, low-clamping voltage ESD protection solutions to safeguard USB ports from ESD and overvoltage transient threats.

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.

物联网的应用和 ESD 防护的重要性
物联网 (IoT) 是一个由嵌入传感器、软件和其他技术的物理设备组成的网络，用于通过互联网与其他设备和系统连接和交换数据。它与云服务器或网关共享数据以进行分析并采取相应的操作（图 1）。物联网的一大应用领域是农业。灌溉水量和时间是根据物联网传感器决定的，这些传感器收集土壤水分含量、养分、肥料用量和天气信息，帮助农户做出明智的决策，防止资源浪费。物联网在制造和工业自动化领域的应用也变得非常流行，从工厂车间、百货商店、跟踪机器性能、测量产品质量、资产跟踪到实时定位系统，不一而足。在智能家居自动化领域中，基于物联网的系统使我们的房屋更安全、更易于维护。
键盘 ESD 防护的重要性
自计算机问世以来，键盘一直是人类和机器之间沟通的主要渠道。多年来，许多技术和界面都发生了变化，但键盘在形式和功能上几乎没有变化。最近，我买了一款高档的无线键盘。最初，它通过蓝牙与计算机通信，没有任何问题。然而，大约一个月后，它突然不能用了。打开内部电路时，我惊讶地发现按键没有静电放电 (ESD) 防护。任何电子设备的键盘、侧键或按钮都容易受到 ESD 的影响，因为用户经常与它们互动。在键盘/小键盘/侧键中添加 ESD 防护装置，可以避免键盘故障等灾难性情况。我们来大致探讨一下 ESD 以及如何保护电子设备免受其影响。
