SiBar Thyristor Surge Protectors

TVBxxxNSC-L Series

Raychem Circuit Protection's SiBar thyristor surge

protection devices are designed to help protect sensitive

telecommunication equipment from the hazards caused

by lightning, power contact, and power induction. These

devices have a high electrical surge capability to help

protect against transient faults and a high off-state

impedance, rendering them virtually transparent during

normal system operation.

SiBar thyristor surge protectors are designed to assist

telecommunication and computer telephony equipment

in meeting the applicable requirements and industry

specifications.

Benefits:

• Helps provide protection for sensitive telecom

electronic equipment

• Low leakage current

• Low power dissipation

• Fast, reliable operation

• No wear-out mechanisms

• Helps designers meet worldwide telecom standards

• Helps reduce warranty and service costs

• Easy installation

• Helps improve power efficiency of equipment

Applications:

• Modems

• Set top boxes

• Fax machines

• POS systems

• Phones, answering machines • Analog and digital linecards (xDSL, T1/E1...)

• PBX systems

• Other customer premise and central office network equipment requiring protection

Features:

• RoHS compliant

• Bidirectional crowbar transient voltage protection

• Voltage range: 58V – 320V with improved

Vdrm/Vbo range

• High off-state impedance

• Low on-state voltage

• High surge capability

• Short-circuit failure mode

• Surface-mount technology

• DO-214AA SMB package

• 10 x 1000 μs 100A surge rating

• Helps equipment comply with TIA-968,

Telcordia GR-1089, IEC61000-4-5, ITU K.20/21/45
