STMicroelectronics has introduced lightning protection IC for telecom equipment in a compact SO-8 package. The SSRP105B1 dual asymmetric transient voltage suppressor helps telecom equipment withstand damage caused by lightning surges and power-cross situations, as specified in various recommendations and standards. In particular, it is claimed to be able to withstand Ipp currents of 50A 5/310 µs and 35A 10/1000 µs, exceeding the levels required by ITU-T K20/21 and GR1089.
Using solid-state relays instead of the usual mechanical ring relays on line cards changes the topology and characteristics of the required protection circuitry. The SSRP105B1 has asymmetric protection characteristics tailored to these requirements.
Features include the ability to handle asymmetric voltages between line and ground of +105 V to -180 V. The IC can also withstand a symmetric voltage between line and line ranging from +180 V to -180 V. The holding current capabilities are an IH+ of 100 mA, and IH- of 150 mA. Other applications include SLICs with integrated ring generators and general PBX circuitry.
