Low Capacitance TVS for High-Speed Telecommunication Systems PROTECTION PRODUCTS Description The LC01-6 transient voltage suppressor is designed to protect components which are connected to high speed telecommunication lines from voltage surges caused by lightning, electrostatic discharge (ESD), and electrical fast transients (EFT). TVS diodes are ideal for use as board level protection of sensitive semiconductor components. The LC01-6 is designed for metallic mode, secondary line side protection in digital line card applications. It features solid-state silicon-avalanche technology for unmatched transient protection without device degradation. The LC01-6 combines TVS diodes with low capacitance compensation diodes to provide an integrated, low capacitance protection solution. Additional features include sub-nanosecond response time, a low operating voltage of 6 volts, and low clamping voltage. The LC01-6 is suitable for use on T1/E1 and xDSL interfaces in equipment such as base stations, routers, and channel service units. The LC01-6 meets the longhaul (outer-building) transient immunity requirements of Bellcore 1089, FCC Part 68 (Type A and B surges), and IEC 61000-4-5.

The device is designed to protect one line pair in differential (Line-to-Line) mode. Pins 18 are connected to line 1 and pins 9-16 are connected to line 2 as shown. All pins should be connected for best results. T1/E1 Linecard Protection A typical long-haul T1/E1 linecard protection circuit is shown below. The LC01-6 is connected between Tip & Ring on the transmit and receive line pairs. It provides protection to metallic (line-to-line) lightning surges per Bellcore 1089 and FCC Part 68. Depending on the application, a high voltage crowbar device (not shown) such as a gas discharge tube (GDT) or TVS Thyristor may be used to suppress common mode (line-toground) sur.
