NOTES: 1. For voltage values at lower temperatures derate at 0.13 %/°C.
            2. Initially, the TISP43xxMM must be in thermal equilibrium with T_J = 25 °C.
            3. The surge may be repeated after the TISP43xxMM returns to its initial conditions.
           4. EIA/JESD51-2 environment and EIA/JESD51-3 PCB with standard footprint dimensions connected with 5 A rated printed wiring  track widths. Derate current values at -0.61 %/°C for ambient temperatures above 25 °C.


Description

These devices TISP4350MMBJ are designed to limit overvoltages on the telephone line. Overvoltages are normally caused by a.c. power system or lightning flash disturbances which are induced or conducted on to the telephone line. A single device TISP4350MMBJ provides 2-point protection and is typically used for the protection of 2-wire telecommunication equipment (e.g. between the Ring and Tip wires for telephones and modems). Combinations of devices can be used for multi-point protection (e.g. 3-point protection between Ring, Tip and Ground).
