The reverse standoff voltage is 43.6 V, so this part protects a 43.6 V rail by breaking down at 48.5 V min and clamping the surge before it reaches downstream silicon. ## AEC-Q101 — the automotive qualification that governs the screening AEC-Q101 Grade means this TVS passed the automotive discrete semiconductor stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness. For a 24 V truck or 48 V mild-hybrid bus, the 43.6 V standoff sits well below the nominal rail, so the diode stays transparent until a load-dump or inductive kick transient arrives.","metaTitle":"1.5SMC51CAHR7G TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC51CAHR7G Zener TVS, 1500W peak pulse, 43.6V standoff, AEC-Q101 automotive grade.
