Preferred Devices
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: 80 Amps 10 x 1000 msec, for
Controlled Temperature Environments
The MMT08B350T3 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

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
1. Allow cooling before testing second polarity.
2. Measured under pulse conditions to reduce heating.
