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
