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
High Surge Current Capability: 50 A 10 x 1000 msec, for Controlled
Temperature Environments
The MMT05B350T3 is used to help equipment meet various
regulatory requirements including: Bellcore 1089, ITU K.20 and
K.21, IEC 950, UL 1459 and 1950 and FCC Part 68
Bidirectional Protection in a Single Device

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
1. Allow cooling before testing second polarity.
2. Measured under pulse conditions to reduce heating.
