Thyristor surge protectors

Bourns recently expanded its TISP thyristor surge protector product line to include new low-capacitance models that allow high data rates up to VDSL2 applications. The new TISP4P015L1N, TISP4P020L1N, TISP4P025L1N and TISP4P035L1N address a range of popular chipset voltages.
These new thyristor surge protectors are designed with a new, lower-capacitance process as a circuit protection solution for ADSL, ADSL2, ADSL2+, VDSL and VDSL2 applications from over-voltages caused by lightning and AC line disturbances. Low capacitance reduces distortion and minimises the effect of using circuit protection in sensitive equipment. The new devices can also be used for T1/E1 driver protection, in customer premise and central office locations and in any transformer-coupled interface which leaves the building.
The new TISP devices are symmetrical, two-terminal thyristor-crowbar devices that can be deployed to protect from line to ground or between the differential driver conductor pair. When placed between the xDSL line driver IC and the transformer, the devices will clamp and switch into an ultra-low impedance state, safely diverting the energy and protecting sensitive equipment from dangerous over-voltage or line disturbance threats that can result in system failure.
