TISP4xxxH3BJ Overview

This TISP® device series protects central office, access and customer premise equipment against overvoltages on the telecom line. The TISP4xxxH3BJ is available in a wide range of voltages and has a high current capability, allowing minimal series resistance to be used. These protectors have been specified mindful of the following standards and recommendations: GR-1089-CORE, FCC Part 68, UL1950, EN 60950, IEC 60950, ITU-T K.20, K.21 and K.45. The TISP4350H3BJ meets the FCC Part 68 “B” ringer voltage requirement and survives the Type A and B impulse tests. These devices are housed in a surface mount SMB (DO-214AA) package.
