Bourns Adds New Ultra-Low Capacitance Thyristor Surge Protectors
Bourns, Inc. announced that the company has expanded its TISP® thyristor surge protector product line to include new ultra-low capacitance models that allow higher data rates to deliver improved VDSL2 performance while providing protection. The new Bourns® Models 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 an optimal circuit protection solution for ADSL, ADSL2, ADSL2+, VDSL and VDSL2 applications from overvoltages caused by lightning and ac line disturbances. Low capacitance reduces distortion and minimizes 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.
Bourns 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 overvoltage or line disturbance threats that can result in system failure.
"These new models offer significant competitive advantages for our customers," said Beverley McKnight, Product Line Manager for Bourns’ TISP products. "These new protectors feature differential capacitance, typically less than 3pF, which makes them our lowest capacitance device. They enable reliable overvoltage protection that meets the faster data rates required by a broad range of VDSL2 applications. Bourns designed these new TISP® products to help our customers deliver high reliability and low cost solutions for their faster data rate products."
As a pricing reference, the new models are priced from $0.30 at 10,000 pieces.
