These dual bidirectional thyristor devices protect central office, access and customer premise equipment against overvoltages on the telecom line. The TISP3xxxT3BJ is available in a wide range of voltages and has an 80 A 10/1000 current rating. These protectors have been specified mindful of the following standards and recommendations: GR-1089-CORE, TIA/EIA-IS-968, UL 60950, EN 60950, IEC 60950, ITU-T K.20, K.21 and K.45. The TISP3350T3BJ meets the FCC Part 68 "B" ringer voltage requirement (VDRM = 275 V). Housed in a 3-pin modified SMB (DO-214AA) package, the TISP3xxxT3BJ range is space efficient solution for protection designs of 80 A or less which use multiple SMBs.
