For a 12 V nominal rail that can spike to 35 V during a load-dump event, this TVS holds the line below the 40 V abs-max rating of most automotive-grade buck converters and linear regulators. The 9.4 V standoff voltage means it does not leak appreciably at the normal 12 V operating level. Listed as Active on the manufacturer's lifecycle record.","metaTitle":"1.5SMC11CAHE3/9AT Vishay TVS, 1.5kW, DO-214AB","metaDescription":"Vishay 1.5SMC11CAHE3/9AT bidirectional TVS diode, 1500W peak pulse power, 10.5V min breakdown, AEC-Q101 qualified.
