TVS Solutions For Network Systems TRANSIENT VOLTAGE SUPPRESSION Networking The following depicts a typical WAN configuration consisting of centralized servers, workstations, hubs and inter-building connections. This configuration is susceptible to damage caused by ESD, EFT and secondary lightning threats. Protection from the above threats, lies in individual discrete protection for I/O ports at all equipment levels. Protection can also be provided at the system interconnecting ports. The protection schemes outlined are recommended for low insertion loss, high signal integrity and low noise/crosstalk with increasing bandwidth. TYPICAL WAN/LAN Transient Voltage Suppression (TVS) devices provide protection at board-level ports from the effects of Electrostatic Discharge (ESD) as defined by IEC 61000-4-2. TVS also provides lightning and AC power fault protection meeting standard requirements such as IEC 61000-4-4, 4-5 and Bellcore GR1089. Solutions for Voice, Video & Data APPLICATION NOTES The following circuits represent several applications for TVS protection from threats of ESD, EFT and secondary lightning.
