The wide range means derating the 1500W peak pulse at elevated ambient follows the standard power-temperature curve. ## Bidirectional — single device for AC or floating rails No power line protection feature is built in; this is a transient suppressor, not a crowbar or filter.","metaTitle":"1.5KE180CA-E3/51 Vishay TransZorb® TVS, 1500W, Bidirectional","metaDescription":"Vishay 1.5KE180CA-E3/51 TransZorb® bidirectional TVS diode, 1500W peak pulse, 154V standoff, DO-201AA axial.
