No power line protection feature is built in; this is a standalone transient clamp, not a filtered suppressor.","metaTitle":"Vishay 1.5SMC13CAHE3/9AT TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC13CAHE3/9AT bidirectional TVS diode, 1500W peak pulse power, 11.1V standoff, AEC-Q101 automotive grade.
