SiBar Thyristor Surge Protectors

TVBxxxRSC-L Series

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.

Applications:

• Central Office Equipment

• Set top boxes

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

• POS systems

• Phones, answering machines

• Fax Machines

• PBX systems

Benefits:

• Helps provide protection for sensitive telecom

electronic equipment

• Low capacitance

• 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

Features:

• RoHS compliant available on all parts

• Bidirectional crowbar transient voltage protection

• Broad voltage range 6V – 400V

• Low capactiance 20pF-45pF @ 50V

• 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,
