1 / 6 page © Semiconductor Components Industries, LLC, 2004 March, 2004 − Rev. 4 1 Publication Order Number: MMT05A230T3/D MMT05A230T3, MMT05A260T3, MMT05A310T3 Preferred Devices 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 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 Unprotected Operation • Surface Mount Technology (SMT) • Indicates UL Registered − File #E210057 • Device Marking: MMT05A230T3: PBF; MMT05A260T3: PBG; MMT05A310T3: PBJ MAXIMUM RATINGS (TJ = 25°C unless otherwise noted) Rating Symbol Value Unit Off−State Voltage − Maximum MMT05A230T3 MMT05A260T3 MMT05A310T3 VDM "170 "200 "270 Volts Maximum Pulse Surge Short Circuit Current Non−Repetitive Double Exponential Decay Waveform (Notes 1 and 2) 8 x 20 µsec 10 x 160 µsec 10 x 560 µsec 10 x 1000 µsec IPPS1 IPPS2 IPPS3 IPPS4 "150 "100 "70 "50 A(pk) Maximum Non−Repetitive Rate of Change of On−State Current Double Exponential Waveform, IPK = 50 A, PW = 15 ms di/dt "100 A/ µs 1. Allow cooling before testing second polarity. 2. Measured under pulse conditions to reduce heating. BIDIRECTIONAL TSPD 50 AMP SURGE 265 thru 365 VOLTS Preferred devices are recommended choices for future use and best overall value.
