Its 145V reverse standoff voltage means it sits across a 120V or 130V nominal rail and stays out of the way until a surge pushes the line above 162V breakdown, then it clamps hard.","metaTitle":"Vishay 1.5KE170AHE3/51 TVS Diode, 1500W, DO-201AA Axial","metaDescription":"Obsolete Vishay 1.5KE170AHE3/51 TransZorb TVS diode, 1500W peak pulse, 145V standoff, AEC-Q101.
