Overview
MMT05A230T3, MMT05A260T3, MMT05A310T3 Preferred Devices Thyristor Surge Protectors High Voltage Bidirectional TSPD http://onsemi.
com 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 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 Non−Semiconductor Devices • Fail−Safe, Shorts When Overstressed, Preventing Continued www.
