TPI

Tripolar protection for ISDN interfaces

Features

■ Bidirectional triple crowbar protection

■ Peak pulse current:

= 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 (Ld

/dt),

especially for very fast transient overvoltages

Application circuit - S interface protection A R or PTC TPIxx GND R or PTC B A R or PTC TPIxx GND R or PTC B 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.
