MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MMT10V275/D Advance Information MMT10V275* MMT10V400* *Motorola preferred devices Thyristor Surge Suppressors High Voltage Bidirectional TVS Devices These transient voltage suppression (TVS) devices 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. Applications include current loop lines in telephony and control systems, central office stations, repeaters, building and residence entrance terminals and electronic telecom equipment. High Surge Current Capability 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.
