Breakdown occurs at 25.7 V minimum, and clamping is specified at 37.5 V maximum — the rail sees no more than 37.5 V during the surge event. ## Package and temperature grade The wide temperature span covers both cold-start conditions in outdoor equipment and the self-heating from repetitive surge events within the pulse derating curve.","metaTitle":"1.5SMC27CA-M3/9AT Vishay TVS, 1500W, 23.1V Standoff","metaDescription":"Vishay 1.5SMC27CA-M3/9AT bidirectional Zener TVS, 1500W peak pulse, 23.1V standoff, DO-214AB.
