This window protects downstream electronics from load-dump and inductive spikes without nuisance triggering on normal bus ripple. ## AEC-Q101 qualification and temperature range Qualified to AEC-Q101, this part is rated for automotive stress tests including temperature cycling, high-temperature reverse bias, and ESD robustness. No power line protection feature is implemented — this is a dedicated transient clamp, not a rail-to-rail steering array.","metaTitle":"1.5SMC440AHE3_AIH Vishay TVS, 1500W, 376V Standoff, AEC-Q101","metaDescription":"Vishay 1.5SMC440AHE3_AIH Zener TVS diode, 1500W peak pulse power, 376V reverse standoff, AEC-Q101 automotive grade.
