Bourns TISP4CO15L1NBased on TISP overvoltage protection technology, Bourns’ TISP4CO15L1N, TISP4CO20L1N and TISP4C025L1N thyristor surge protector devices (TSPDs) provide protection for ADSL, ADSL2, ADSL2+, VDSL, and VDSL2 ports in modems or telephone exchanges. The feed-through-packaged devices are designed to reduce line failure and help increase xDSL line reach to customers with a capacitance of 9 pF. The 2-terminal thyristor-crowbar devices can be used to protect between conductors, or a pair of devices can be deployed to protect from line to ground. When placed between the xDSL line driver IC and the transformer, they will clamp and switch into a low-impedance state and divert the energy transferred by the xDSL coupling transformer. Pricing is $0.20 in 1,000,000 quantities through distribution.
