Description

Dedicated devices for ISDN interface and high speed data telecom line protection. Equivalent to a triple Trisil™ with low capacitance.

Features

■ Bidirectional triple crowbar protection

■ Peak pulse current: IPP = 30 A , 10/1000 µs

■ Breakdown voltage:

– 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
