Thyristor Surge Protectors
ON Semiconductor Corp

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.
High Surge Current Capability: 50 Amps 10 x 1000 sec; Controlled Temperature Environments in the SMA package Meets Telecom Standards The MMT05A230T3 Series is used to help equipment meet variousregulatory 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 Non-Semiconductor Devices Fail-Safe, Shorts When Overstressed, Preventing Continued Unprotected Operation. Surface Mount Technology (SMT) Device Marking: MMT05A230T3: TBD; MMT05A260T3: TBD; MMT05A310T3: TBD
