MMT05B230T3, MMT05B260T3, MMT05B310T3 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 The MMT05B230T3 Series 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 Device Marking: MMT05B230T3: RPBF; MMT05B260T3: RPBG; MMT05B310T3: RPBJ, and Date Code MAXIMUM RATINGS (TJ = 25°C unless otherwise noted) Rating Off−State Voltage − Maximum MMT05B230T3 MMT05B260T3 MMT05B310T3 Maximum Pulse Surge Short Circuit Current Non−Repetitive Double Exponential Decay Waveform (Notes 1. and 2.)
