It clamps transients at 658V maximum from a 408V reverse standoff level, with a minimum breakdown voltage of 456V. The single unidirectional channel handles 2.28A peak pulse current under the 10/1000µs waveform, which is the standard telecom surge shape — the same waveform used for IEC 61000-4-5 surge testing. AEC-Q101 qualification means this part passed the automotive stress tests: temperature cycling, high-temperature reverse bias, and pre-conditioning for surface-mount reflow. Sourced to order through independent distribution channels.","metaTitle":"1.5SMC480AHM3_A/H Vishay TVS, 1500W, 658V Clamp, DO-214AB","metaDescription":"Vishay 1.5SMC480AHM3_A/H Zener TVS diode, 1500W peak pulse, 408V standoff, 658V clamp.
