The part is a single-channel, unidirectional suppressor in a DO-201AA (DO-27) axial-lead package, through-hole mounted.","metaTitle":"Vishay 1.5KE480-E3/73 TransZorb TVS, 1.5kW, 686V Clamp","metaDescription":"Obsolete Vishay 1.5KE480-E3/73 TransZorb Zener TVS diode, 1.5kW peak pulse, 389V standoff, 686V clamp.
