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 breakoverâtriggered crowbar
protectors. Turnâoff occurs when the surge current falls below the
holding current value.
Secondary protection applications for electronic telecom equipment
at customer premises.
⢠High Surge Current Capability: 50 Amps 10 x 1000 μsec; for
Controlled Temperature Environments in the SMA package
⢠The MMT05A230T3 Series is used to help equipment meet various
regulatory requirements including: Telcordia 1089, ITU K.20 &
K.21, IEC 950 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 NonâSemiconductor
Devices
⢠FailâSafe, Shorts When Overstressed, Preventing Continued
Unprotected Operation
⢠Surface Mount Technology (SMT)
⢠Indicates UL Registered â File #E210057
⢠PbâFree Packages are 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.
