Surface-mount, supplied on tape and reel — pick-and-place compatible for high-volume assembly with the reflow profile matched to the SnAgCu solder paste window.","metaTitle":"1.5SMC91CAHE3/57T, Vishay TVS Zener, 1.5 kW 125 V clamping","metaDescription":"Active AEC-Q101 qualified TVS Zener, 1.5 kW peak pulse, 125 V clamping, 77.8 V standoff, DO-214AB SMC.
