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)

•

Indicates UL Registered − File #E210057

• Pb−Free Package is Available

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.
