Advance Information
Thyristor Surge Suppressors
High Voltage Bidirectional TVS Devices
These transient voltage suppression (TVS) devices prevent overvoltage
damage to sensitive circuits by lightning, induction and power line crossings.
They are breakover–triggered crowbar protectors. Turn–off occurs when the
surge current falls below the holding current value.
Applications include current loop lines in telephony and control systems,
central office stations, repeaters, building and residence entrance terminals and
electronic telecom equipment.
• High Surge Current Capability
• Bidirectional Protection in a Single Device
• Little Change of Voltage Limit with Transient Amplitude or Rate
• Freedom from Wearout Mechanisms Present in Non–Semiconductor De-
vices
• Fail–Safe. Shorts When Overstressed, Preventing Continued Unprotected
Operation.
