Description

The 8011NVS is a dedicated device for ISDN interface and high-speed data telecom line protection. It is equivalent to a triple Trisil™ with low capacitance.

Specifications and 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

Application Scenarios

The 8011NVS is ideal for use in high-speed data telecom lines and ISDN interfaces where low capacitance and fast signal transmission is required. It is also helpful in ensuring longitudinal balance and providing reliable protection against overvoltages introduced by the parasitic inductances of the wiring for very fast transient overvoltages.

Comparison

• Low capacitance from lines to ground
• Good capacitance balance between lines
• Fixed breakdown voltage in both common and differential modes
• Same surge current capability in both common and differential modes
• Reliable protection
