TISP3070T3
Description
These dual bidirectional thyristor devices protect central office, access and customer premise equipment against overvoltages on the tele line. The TISP3xxx T3BJ 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 remendations: 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 TISP3xxx T3BJ range is space efficient solution for protection designs of 80 A or less which use multiple SMBs.
These devices allow signal voltages, without clipping, up to the maximum off-state voltage value, VDRM, see Figure 1. Voltages above VDRM are limited and will not exceed the breakover voltage, V(BO), level. If sufficient current flows due to the overvoltage, the device switches into a low-voltage on-state...
