For a pin-compatible replacement within the same 1.5SMC family, a parametric cross-reference against the 456V breakdown and 658V clamping limits is the practical path — the DO-214AB footprint stays constant across the series. ## Clamping performance and the 1500W rating For a 400V nominal bus with a 10% tolerance, the 408V standoff provides margin against steady-state overvoltage without nuisance triggering. ## Automotive qualification and temperature grade AEC-Q101 qualified — the automotive discrete semiconductor stress test suite covering temperature cycling, high-temperature reverse bias, and ESD robustness. Unidirectional Zener type with a single protection channel — correct for DC rail clamping where the transient polarity is known.","metaTitle":"1.5SMC480AHE3_A/H TVS Diode, 1500W, 408V, DO-214AB","metaDescription":"Obsolete Vishay 1.5SMC480AHE3_A/H Zener TVS, 1500W peak pulse, 408V standoff, AEC-Q101 qualified.
