Breakdown starts at 48.5 V minimum, and clamping is guaranteed at 70.1 V maximum across the full peak pulse current. Tape & Reel packaging is standard for the SMC footprint.","metaTitle":"1.5SMC51CAH TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC51CAH bidirectional Zener TVS, 1500W peak pulse, 70.1V clamping, AEC-Q101 automotive grade.
