- TPI80N: 80 V - TPI120N: 120 V - Available in SO-8 package - Low dynamic breakover voltage: - TPI8011N: 120 V - TPI12011N: 170 V ## **Benefits** - Low capacitance from lines to ground, allowing high speed transmission without signal attenuation - Good capacitance balance between lines to ensure longitudinal balance - Fixed breakdown voltage in both common and differential modes - The same surge current capability in both common and differential modes - A particular attention has been given to the internal wire bonding. The “4-point” configuration ensures a reliable protection, eliminating overvoltages introduced by the parasitic inductances of the wiring (LdI/dt), especially for very fast transient overvoltages ## **Complies with following standards** - CCITT K17-K20 - 10/700 µs, 1.5 kV - 5/310 µs, 38 A - VDE 0433 - 10/700 µs, 2 kV - 5/310 µs, 50 A - VDE 0878 - 1.2/50 µs, 1.5 kV - 1/20 µs, 40 A - IEC 61000-4-2 level 4 - 0.5/700 µs, 1.5 kV - 0.2/310 µs, 38 A ## **Description** Dedicated devices for **ISDN** interface and high speed data telecom line protection. Equivalent to a triple Trisil™ with low capacitance. ## **Figure 1. Functional diagram** **==> picture [152 x 111] intentionally omitted <==** **----- Start of picture text -----**

This component uses an intemal structure resulting in symetrical characteristics with a good balanced behaviour. Its topology ensures the same breakdown voltage level for positive and negative surges in differential and common mode. 5/9 **Ordering information scheme** **TPI** ## **Figure 9.
