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 powe
r
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
• 10 x 1000 μs 50A surge rating
• Helps equipment comply with TIA-968,
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
