SiBar Thyristor Surge Protectors
TVAxxxNSA-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:
Features:
• RoHS compliant
• 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
• Bidirectional crowbar transient voltage protection
• Voltage range: 170V – 275V with improved
Vdrm/Vbo range
• 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
• Fax machines
• Phones, answering machines
• PBX systems
• Set top boxes
• POS systems
• Analog and digital linecards (xDSL, T1/E1...)
• Other customer premise and central office network equipment requiring protection
