SiBar Thyristor Surge Protectors
TVBxxxSC-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: 170V – 300V 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
