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:
⢠Helps provide protection for sensitive telecom
electronic equipment
⢠Low leakage current
