Preferred Device
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.
Secondary protection applications for electronic telecom equipment
at customer premises.
Features
• Outstanding High Surge Current Capability: 100 A 10x1000 msec
Guaranteed at the extended temp range of −20°C to 65°C
• The MMT10B230T3 Series 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)
• Complies with GR1089 Second Level Surge Spec at 500 A
2x10 msec Waveforms
• Indicates UL Registered − File #E210057
• Pb−Free Packages are Available
BIDIRECTIONAL TSPD
100 AMP SURGE
265 thru 365 VOLTS
