Thyristor Surge Protectors
High Voltage Bidirectional TSPD
These Thyristor Surge Protective devices (TSPD) 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.
• High Surge Current Capability: 80 Amps 10 x 1000 µsec, for
Controlled Temperature Environments
• The MMT08B310 is used to help equipment meet various regulatory
requirements including: Bellcore 1089, ITU K.20 & K.21, IEC 950,
UL 1459 & 1950 and FCC Part 68.
• Bidirectional Protection in a Single Device
• Little Change of Voltage Limit with Transient Amplitude or Rate
• Freedom from Wearout Mechanisms Present in Non−Semiconductor
Devices
• Fail−Safe, Shorts When Overstressed, Preventing Continued
Unprotected Operation
• Surface Mount Technology (SMT)
•
