JKSEMI 5-2R90

Gas discharge tubes are primarily used for overvoltage protection of telephone exchange main distribution frames and subscriber terminal equipment. Compared to conventional GDTs, they provide a higher level of protection, and their fast, precise breakdown voltage makes them suitable for MDF (Main Distribution Frame) modules, high-speed data telecom applications (e.g., ADSL, VDSL), and surge protection on power lines. They offer two forms of protection: combined with varistors to guard against the bulk of sustained voltage pulse spikes, and protection against transient overvoltages transmitted through telephone networks and control networks.
