2017 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 02/23/17 TVS Diode Arrays (SPA Diodes) Intra-Building - Robust Lightning Protection The diagram show below is typical for indoor network line and equipment applications. The TVS Diode Array device combination is rated up to 100A, per the GR-1089 standard. BROADBAND NETWORK PORT PROTECTION The following are examples of the implementation of ESD and lightning suppression for Ethernet ports (RJ-45 connectors). Note that the diagrams shown below represent 10Mbps and 100Mbps applications -- For 1Gbps applications, the circuit protection should be double of what is shown. For additional design examples, guidance and application assistance, please contact Littelfuse.
