It protects a 102V nominal rail: the reverse standoff voltage is 102V, breakdown occurs at 114V minimum, and clamping maxes at 165V when the 9.1A peak pulse current (10/1000µs waveform) flows. That 165V clamp keeps downstream silicon within its avalanche rating during a surge. ## DO-214AB SMC — surface-mount, standard footprint Packaged in DO-214AB (SMC) with a supplier device package designation of DO-214AB (SMCJ). The surface-mount footprint matches the industry-standard SMC pad layout used across 1500W TVS families, making it a drop-in for existing PCB layouts designed for this power class. Operating junction temperature spans -65°C to 150°C, covering industrial enclosures and automotive under-hood environments where ambient heat plus self-heating from repetitive surges must stay within the die's thermal budget.","metaTitle":"1.5SMC120A-E3/57T Vishay TVS, 1500W, 102V, DO-214AB","metaDescription":"Active Vishay 1.5SMC120A-E3/57T Zener TVS diode, 1500W peak pulse, 102V reverse standoff, DO-214AB.
