Thyristor Surge Protector
ON Semiconductor Corp

Product Description 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.
Outstanding High Surge Current Capability: 100 Amps 10x1000 msec Guaranteed at the extended temp range of 20C to 65C The MMT10B230T3 Series is used to help equipment meet variousregulatory 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-SemiconductorDevices. Fail-Safe, Shorts When Overstressed, Preventing ContinuedUnprotected Operation. Surface Mount Technology (SMT) Complies with GR1089 Second Level Surge Spec at 500 Amps2x10 msec Waveforms Indicates UL Registered - File #E210057 Device Marking: MMT10B230T3: RPDF; MMT10B260T3:RPDG; MMT10B310T3: RPDJ, and Date Code Pb-Free Packages are Available
