加利福尼亚州河滨，2009年1月27日电子组件的领先制造商和供应商Bourns，Inc。今天宣布，旨在保护ADSL，ADSL2，ADSL2+，VDSL和VDSL2端口的新型低电容浪涌保护器家族，以模量或电话交换为单位。Designated the TISP4C015L1N, TISP4C020L1N and TISP4C025L1N, Bourns’ new family of surge protectors have a small footprint and are designed to reduce line failure and help to increase xDSL line reach to customers with a low capacitance of 9 picofarads (pF) and a feed-through package that is designed to provide the lowest possible protection voltage. This new family of Thyristor Surge Protection Devices (TSPD) is based on Bourns industry-leading TISP® overvoltage protection technology that follows in the company's history of providing leading-edge and cost effective solutions and recommendations.
Bourns技术营销经理Koenraad Rutgers说：“ Bourns的新型TISP电涌保护器家族是调制解调器或电话交换端口的理想解决方案。“我们已经根据我们的产品性能从OEM客户那里获得了设计胜利，该产品提供了帮助减少线路故障并最大化XDSL线路触及的解决方案。”
As the VDSL market continues to grow with more than 100 million lines installed in 2008 alone, Bourns’ new family of surge protector products is designed to protect xDSL line-driver interfaces at both ends of the line from overvoltages from AC power system or lightning-flash disturbances. These symmetrical protectors are two-terminal thyristor-crowbar devices and 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, this protector will clamp and switch into a low-impedance state, safely diverting the energy transferred by the xDSL coupling transformer. The low capacitance design makes these devices an optimal choice for designs from ADSL all the way up to 30 MHz VDSL2. The alternative to TISP surge protectors had previously been simple steering diodes which allow energy to reach the protected line drivers, potentially resulting in line damage.
