The 1500 W peak pulse rating at 10/1000 µs waveform means the device can absorb a 9.1 A pulse for 1 ms — sufficient for industrial surge environments per IEC 61000-4-5 if the source impedance is high enough to limit current. The cathode band identifies the unidirectional orientation; the anode is the tab end. Standard SMC pad geometry with a 0.080-inch wide copper land per terminal is adequate for the 1500 W pulse energy. The base product number is 1.5SMC120, and the -M3/57T suffix denotes the Tape & Reel packaging option for automated assembly.","metaTitle":"1.5SMC120A-M3/57T Vishay TVS, 102V standoff, 1500W","metaDescription":"Active Vishay 1.5SMC120A-M3/57T Zener TVS, 1500W peak pulse, 102V standoff, DO-214AB.
