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.
