SiBar Thyristor Surge Protectors

TVAxxxSA-L Series

SiBar thyristor surge protection devices 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 assist designers to meet

telecommunication and computer telephony equipment

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

• Assists designers to meet worldwide telecom

standards

• Helps reduce warranty and service costs

• Easy installation

• Helps improve power efficiency of equipment

Features:

• RoHS compliant

• Bidirectional crowbar transient voltage protection

• Voltage range: 170V – 270V

• High off-state impedance

• Low on-state voltage

• High surge capability

• Short-circuit failure mode

• Surface-mount technology

• DO-214AC SMA package

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

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
