Designed to protect ADSL, ADSL2, ADSL2+, VDSL, and VDSL2 ports in modems or telephone exchanges, the TISP4CO15L1N, TISP4CO20L1N, and TISP4C025L1N surge protectors exhibit a low capacitance of 9 pF. The 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. Placed between the xDSL line driver IC and transformer, the components will clamp and switch into a low-impedance state, diverting the energy transferred by the xDSL coupling transformer. The TISP4 surge protectors cost $0.20 each/1,000,000. BOURNS INC., Riverside, CA. (951) 784-3100.
